Games Learning Society conference 2014: a debrief. Although, in short, it was pretty cool.

logo

So, I’ve just returned from the Games Learning Society 2014 conference, held in Madison Wisconsin, and I’m all abuzz with new and grand ideas! Essentially, I went in as someone new to the #gaming #learning #academia field (or a “noob” as the vernacular goes). And although their website only provides a peripheral description of what the conference is about (with only the briefest of blurbs on the GLS’ about page), this particular conference was highly recommended by Barry Joseph, a friend and colleague with whom I’ve been working with on the AMNH Pterosaur Phylo deck. As well, Barry is a highly respected member of the games and learning community, which is to say that if I accidentally refer to him as a “Yoda” in the field, I mean it only in the most positive of ways.

Anyway, a few months back, I literally asked Barry to pass on a recommendation to the following query:

“If I only go to one gaming conference to get my feet wet in this type of community, what would that most excellent conference be?”

And so here we are. Fatigued mentally and physically from last week’s intense learning and networking, but also most definitely inspired to contribute more to the community. This is actually part of the challenge: so many interesting discussions and ideas surfaced with this interdisciplinary crowd, that I’m a bit befuddled on how to proceed and what to focus on next. My work plate is already very full, nutritious and rich, so navigating new opportunities is a little intimidating to say the least. Which is why, I’m going to write this post to organize my thoughts, but doing so, I hope readers will also get a taste of the wonderful community as well as the general vibe (academic or not) of this conference, so as to consider why they might like to attend in future years. Anyway, with this in mind and in no particular order…

- – -

one Firstly, I have to give kudos to Edge Quintanilla, Margaret Chmiel and Barry who graciously allowed me to play in their sandbox (as in metaphorically an accepted panel presentation/discussion – “Advancing STEM Learning with Games in Civic and Cultural Institutions: A Play, Critique, and Discussion Session“).

The workshop was both engaging for me (and I think the attendants), but I’m hopeful that maybe in the future the four of us can work on something together. I say this because I kind of think the four of us would make a good “SuperFriends” team, since Barry is from New York’s American Museum of Natural History (let’s say he’s “Superman”), Margaret is from the Smithsonian (let’s say she’s “Wonder Woman”), and Edge is from Chicago’s Field Museum (let’s say he gets to be “Batman”). What you’ll notice is that they inadvertently represent a trifecta of three of the most iconic (natural history) museums in North America. Maybe, I can act as that connecting, comedic, valued, but occasionally mocked (I’m o.k. with this) 4th wheel – or in other words, maybe I get to be one of the Wonder Twins. O.k. that came out wrong, but you get the point.

one I should point out that my official gateway to the gaming scene is via the Phylo Trading Card Game project. This (in case you didn’t know) is an open source biodiversity game project that is essentially attempting to crowdsource a flexible trading card platform that allows for games to be designed around real organisms (indeed, the brilliant but surreal crowdsourcing efforts to date were inspired by knowledge that children know way more about Pokemon than they do about real creatures). It was cool to see such positive reaction to the project, both in commentary, but maybe more importantly in the many people who “got it” right away and started discussing possible “other” uses of the platform.

This ranged from folks like Ariel Marcy who has developed a card game about evolutionary clade sorting (see this successful Kickstarter); to Owen Gottlieb who is thinking about card games that reflect on historical, as well a religious culture, content (I love that). As well, I had a chance to chat with Tom Toynton, and found out that he also has a biodiversity related trading card game that sounds awesomely in tune with some of the mandates of the Phylo project.

A quick chat with Scott Price from BrainPOP was also pretty interesting. Here, he mentioned liking the idea of adapting and improving upon an open trading card platform (such as Phylo) so that it may be more widely used by teachers and students. This was quite intriguing especially given BrainPop’s presence in the educational market. The one nuance that would need navigating, however, is to ensure that the Phylo brand and game mechanic remain open, even if used by commercial vendors. To that end, the Phylo project is currently in the process of determining the right legal framework to allow “for profit” entities to utilize Phylo resources (branding, game mechanics, use of cards, etc) in a way that protects the open philosophy of community driven resources, whilst providing an option for others to commercialize and copyright their own “edits.” In general, I’m hopeful this will add another layer of flexibility in the project, so that more resources can be created in both non-commercial and commercial contexts (p.s. if there are any intellectual property lawyer types that want to help with this, then do let me know).

Finally, at the conference I referenced the fact that Phylo’s DIY card making process would be greatly simplified over this summer (to the point where ideally a 7 year old can do it), with the intent that this would make it a lot easier for things like classroom decks to be created by teachers and their students (you can see examples here, here, here, and here). This proved really popular with the many teachers I chatted with. For those interested, the plan is that when this functionality is released (and note that you can do this right now – it’s just a bit complicated), we’ll likely beta test how it goes by only releasing 100 or so “teacher” accounts.

gls1402

one Still related to the Phylo project, one of most interesting conversations I had, revolved around the possible use of ARIS. This is basically an open source mobile app platform designed to allow educators to tie in GPS and QR code functions into tour or game like immersion experiences.

In Phylo’s case, the discussion was around whether such a platform might be amenable to addressing one of the central criticisms of the Phylo card game – that is, if you want to educate and/or advocate for biodiversity concepts, wouldn’t it be better to simply make people go outside, and not stay indoors playing a card game? Now, there’s all sorts of discussion we can have about the validity of this criticism, but I have always thought that an app that somehow entices Phylo players to go “outside” would be a lovely endeavour.

In this respect, there seems to be a lot of potential, ranging from using the cards as a wildlife checklist, using the cards to navigate a physical tour within a defined space (like a park or a museum), or even (if we ratchet up the creativity) a game wholly developed that draws folks into the card world, whilst moving around an outdoor environment with markers, goals, and/or tasks. I was also of mind about seeing how ARIS could connect with the Encyclopedia of Life. Given the deep and scientifically sound meta data collected by EOL, it seemed like there’s a no-brainer in seeing how these two could somehow mix, especially with their similar open source philosophy. More so, since the Phylo project is currently working with EOL on something very cool.

Anyway, it was great chatting with David Gagnon (with whom I not only share a first name, but also apparently and strangely, identical fashion sense) and Chris Holden on this. It sounds like a follow up proper is best done with a bit of funding, but this is something that has great potential and I’m definitely thinking more about this.

gls1403

one I also love that this was a conference where being an advocate for role playing games has an air of heroism to it. And being a former Dungeon’s & Dragon player, and more recently sharing this fine way of playing with my children, it was cool to see how some people were using RPGs as a portal to better learning. In particular, I had a chance to pick two remarkable brains, that being Trent Hergenrader and Kip Glazer. In their case, use of RPGs naturally flowed around deeper practices on narrative, storytelling, and creating richer context around such writing. It sounded really quite wonderful, with Trent using this innovative approach around creative writing world generation (see an example here with Hellwaukee), and Kip incorporating similar practices to get her high school students to not only better understand a work of literature like Beowulf, but to completely and wholly own it.

Anyway, I’m totally inspired to see if I can use a RPG based mechanic in my one undergrad course I teach – this would be ASIC200, a course with 2nd year undergrad students from both the Faculty of Arts and the Faculty of Science, all in together to learn about a few chosen global issues (climate change and genomics for instance). In particular, rather than ascribing learning objectives around writing skills, this would be more about somehow getting students to think, act and perceive the world view of the other (the whole art versus science thing I guess). As the token sciencegeek in the course, I’ll be chatting with Allen Sens (the humanities geek) on whether this might be doable, especially since we’ve been thinking about possibly moving towards a “flipped” class scenario, thereby freeing up a good chunk of class time.

one Kip is also something of a force of nature! We got to speaking about teacher professional development opportunities and from this, we discussed the idea of hosting a teacher hackathon. Here, the goal would be to host a day session with a good number of keen teachers (my facilities can easily accommodate such an event with anywhere between 10 and 90 teachers), and provide a structured but relatively open template where they’ll be charged to explore existing materials, and attempt to come up, or “hack” something better.

Specifically, Kip and I were thinking a session where teachers will come out with a number of fleshed out (and shared) lesson plans/goals/ideas, that could focus on game based learning and mathematics (Kip’s true love). Add to that, the beauty of a hackathons is that it also embody ideals where it’s o.k. if the lesson plans are not perfect or great even. The point is that they represent a viable prototype, and something that can be built upon, more so with this new network of teachers that you’ve just spent intense time with.

Anyway, Kip has already thought through a way to start this in earnest, and the first step involves putting ideas to paper: and why not under the guise of chapter proposal for a book? I’m currently working on seeing if I can bring her out to Vancouver for a visit, so fingers crossed.

no6 In the fall, I’m about to start a research project around children’s impressions of “science” and their impressions of “creativity,” with a mind to explore how they might intersect (or not). This, you can learn more about here, but what was cool was a chance to meet someone working on a research initiative with similar elements. This individual is June Ahn, who has this intriguing project called “Sci-Dentity” where they:

“…are creating an after-school program for inner-city, middle school youth in Washington DC Public Schools (DCPS) where students will create science inspired stories with different media (e.g. graphic novels, short stories etc.) […] A main focus of our research will be to explore how science fiction and other creative narrative projects can be designed and used to help young people imagine the exciting ways that science impacts us as human beings and shape who we are.”

This is especially cool for me, because the research that I’m involved with revolves around a fieldtrip program (the Science Creative Literacy Symposia) which essentially provides an informal educational experience that combines science experimentation with expository creative writing. Anyway, definitely will have to follow up with June to see where we might work together, and possibly even bridge research outcomes, given the potential overlap existing. This is also another example where twitter is proven to be a valuable tool – the whole discussion began via monitoring the #gls14 twitter feed.

no7 The description of the next potential project is purely tangential, in that it involves Pokemon and that this somehow relates to the fact that the Phylo project happens to reference Pokemon as a call to action. In any respect, this was spawned by a great conversation with Christian de Luna, a Pokemon devotee, which revolved around Pokemon’s mechanics emulating evolutionary concepts, and how that might be taken advantage of to, you know, actually look at evolutionary concepts proper. I have to say that this is very enticing to me especially as someone who is a geneticist and very familiar with evolutionary biology. How cool would it be to design something around this angle? Anyway, I’m totally game on as a collaborator (maybe from the content expertise angle, but also as a director of an educational lab where we can discuss elements of seed funding and certainly roll out betas to children of various ages), although I am most intrigue by what this grant proposal might look like, as well as where it would go!

no8 Finally, I have to mention that part of the reason of going to #gls14 was to immerse myself a little in the academic culture of people who research games for learning. And there’s probably no better way of doing this than hanging out with the amazing young researchers who shared their time with me. In this respect, I had a lovely time hanging out with folks like Olivia Stewart, Kelly Tran, Niels Quinten, Lori Ferguson, Christian de Luna, Andrew Jefferson, Jeff Holmes, Joey Huang, and Lien Tran to name a few. Thanks to all who were so generous with their time – definitely do look me up when you’re next in Vancouver.

Anyway… In the end, this whole conference was definitely time well spent, but now for the difficult part. Basically, I’m sold – I do want to dig a little deeper into games research, but the reality is that I can only pursue a few of these great ideas in earnest. This is both in terms of intellectual engagement (collaborative grant proposal anyone?) but also in terms of thinking about possible seed funding support. Regardless, I’m pretty sure the GLS conference is now going to be one of those conferences I try to attend on a yearly (or at least biannual) basis.

The folks over at Urbana-based Electroninks Incorporated just launched a Kickstarter project for a new kind of pen that draws fuctional electronic circuits instantly. Called the Circuit Scribe, the handy little device works like a regular ballpoint pen and releases a non-toxic conductive silver ink that dries instantly.

T-shirt now available in honour of my lab’s Molecular Biology 5 day professional workshop (next one held in Vancouver from Feb 17th to 21st, 2014 – more details here). Note that all revenues go towards my lab’s outreach programming, which can be surveyed here.

Anyway, if you’re a scientist in need of a quick refresher in these techniques, or someone in a parallel field and want to learn more about the various methodologies that keep infiltrating your research discipline, then take a peek and consider signing up (or pass along to a colleague).

Also, if you’ve got a friendly neighbourhood bulletin board nearby, it would be AWESOME if you could put this poster (pdf) up somewhere.

The Earth as if you were watching on the ISS. Timelapsed, gorgeous, inspiring, and obvious that our planet looks very delicate indeed.

So, this past weekend, I watched this video. A few seconds in, I stopped it, turned off the lights, plunked on a pair of headphones, and then expanded the view to full HD mode. Then, under these conditions, I watched it fully.

It’s hard to explain but I found this video very moving. Moving for all sorts of reasons, I suppose. It was beautiful, the Earth was beautiful, but it was also an inspiring glimpse of much needed perspective. The Earth looked so small, especially when backdropped against the cosmos, and for reasons I can’t fully explain, the Earth also seemed so delicate – like it was obvious why we need to take good care of it.

Chalk it up to just another example of an interdisciplinary crossroad. Here we have footage that had a perfunctory scientific and technological basis, and yet some of the “data,” the “observations,” the footage that was collected, when translated by a skilled practitioner, clearly had a power beyond those acts of hypothesis generation and hypothesis support.

This is an interesting dynamic – how beautiful pictures, beautiful sounds, or beautiful words can inform the scientific endeavour, although it’s a dynamic that doesn’t appear to have a lot of research behind it. So maybe it’s worth taking a closer look? Or maybe not? After all, does looking too deeply, working out measurements or concocting algorithms to explain why I feel the way I feel when I watch this video, would this result in a loss of that wonderful perspective, or would it allow us to do it even better?

OMG! A functional Lego microscope! (a.k.a. New things to ask for in your science research grants?)

You know what this means? That’s right: line items on science grants asking for lego funding! (of course, whether such an ask would be successful is another matter entirely).

The gist of some new research directions. On impressions around science and creativity, and the space between them.

This is just a heads up that my lab will be “having a go” at some new research queries. Specifically, one that examines the interspace between impressions of “science” and impressions of “creativity.” In fact, tonight I’m heading to Calgary to meet up with Marie-Claire Shanahan and take a crack at the first draft of the grant proposal. In the meantime, however, you can stay in the loop with our progress at our open research blog. Below is a quick (grant-speak-ish) write up of what we hope to do.

Science is a creative endeavor. This is obvious to many who actively participate in scientific research as they see their work as a continuum of creation, whether it leads to product or discovery. Similarly, the notion that science is creative is also obvious when viewed under the lens of those who study “creativity,” a term that is rich with diverse interpretations but often abridged as “the ability to create work that is both novel and appropriate” (Sternberg and Lubart, 1999). Despite this clear agreement, public perceptions around science, including those perpetuated in classroom settings, almost universally exclude the role of creativity (Braund, 1999). As a result, this detachment leads individuals away from an authentic view of science, which not only creates false impressions, but could also lead to a loss of scientific identity (where one considers “who we think we must be to engage in science”, Calabrese Barton, 1998, p. 379). This, in turn, could culminate in an unintended estrangement.

Under this context, this research will aim to explore notions and impressions of both authentic science and creativity, and the effect of science educational programming that actively promotes their connection. Here, the aim is to build research queries around the activities of a science education lab that: (a) operates within, and therefore has unparalleled access to, a highly regarded multidisciplinary scientific research unit – the Michael Smith Laboratories at the University of British Columbia; and (b) has already shown an inclination towards programming that relies on collaborations between scientific and artistic communities. Given that this programming also extends over a variety of school grade levels (elementary and secondary), takes place in a state of the art genetics research (authentic) space, involves participant numbers in the 1000s, and is malleable towards specific research interests; this collaboration and this research is viewed as an unprecedented opportunity to delineate the effect of the science and creativity disconnect in public perception.

Since, we’ve set this up as an open blog and all, we’d love to hear what people think. Check it out here.

“This is a piece for Delaware Today about young girls losing interest in science,technology, engineering and math related studies. The state’s schools and businesses are hoping to turn all this around. I love it when I come up with a few sketches that I still want to use for something and this was one of those times. A big thanks to AD Kelly Carter!”

The “I’m at a science conference at the product displays, and I want to see how much free stuff I can get” game.

By DAVID NG

The below is a point sheet I occasionally  use for my molecular biology class.  Essentially, if the timing is right, there might be one of those large scientific equipment/product showcases on campus, and if so, it’s always fun to let loose a pack of graduate students hungry for free geek-related swag.  Note that this only works if you happen to have an hour or so, in between lab steps.

It’s quite funny to see this game in action (it has a real Amazing Race vibe to it), because if you get students who are in the zone, you’ll be surprised at how much cool stuff they get.  Especially, since these trade shows seem to get stingier and stingier each year.  Interesting sidebar:  this use to be an annual activity given that UBC’s big scientific trade show consistently fell on our class day.  However, there was this one year where the class haul was simply unreal, incredible, a bit offensive really and funny thing – the trade show dates were changed the following year. Anyway, I’ve always wondered if the move had anything to do with our silly game…

Dr. Oyekanmi Nashiri is a busy individual who exudes enthusiasm, embraces optimism, and covets high expectations. Then again, as the principle organizer of a somewhat curious scientific program, he would have to be all that and more – some would even say that his good intentions place him squarely in the category of certified nutbar. Nash (as he prefers to be called) has spent the better part of his scientific career developing and implementing the West African Biotechnology Workshops, a focused attempt on bringing scientific expertise and potential research collaborations to his homeland, Nigeria. Which is to say, he is intent on bringing the realm of high technology into an otherwise struggling country.

Ironically, I was thrown into this mix by virtue of my reputation as a university instructor, the lure of traveling to an altogether foreign place, and the somewhat naïve notion that this challenge could bring some merit into the developing world. Ironic because part of the appeal stemmed from my being guilty of harboring the same preconceptions about Africa that every other non-African seems to have. That is, the whole romantic ‘Out of Africa’ thing, where the nations that hold the continent together live in natural but primitive splendor.

“Which,” as Nash would often say “is all nonsense.” Nash is an animated speaker – his continuous gestures and movements betray his scientific patience. “You can’t think of Africa as one place, one culture. It is distinction within distinction. Every place is separate and special from the other. We are not going to Africa, David, we are going to Nigeria.” And in retrospect, he couldn’t have been more correct.

Nigeria is a country of unfathomable extremes, the kind that Meryl Streep and Robert Redford would take little comfort in. It has a population of over 100 million individuals crammed into a small wedge of land that is the coastal armpit of West Africa. Its growth rate is such that the population is expected to rise to about 300 million individuals by 2025 – a figure that would mirror that of the United States, except that it would be squished into an area half the size of Alaska. Such numbers also give rise to extreme cultural diversity, which is well exemplified by the more than 250 different ethnic groups, of which three stand out and comprise 65% of the population (Hausa in the Muslim north, Igbo in the agrcultural lands of the south-east, and Yoruba in the urban south-west.). In spite of this dominance, the remaining groups certainly do not want to be ignored. Each has its own language; each has its own way of life; and each has its own fiery brand of pride. In short, Nigeria is as close as it gets to a real cultural melting pot, African or otherwise. Quite simply, it is distinction within distinction within distinction.

It is also not a very nice place to visit. The travel advisories within the Canadian Department of Foreign Affairs and International Trade say it all rather succinctly:

The official language is English. Tourist facilities are limited. Power shortages and low water pressure are common. Telecommunications are unreliable. Those attempting to contact the police may have difficulty getting through. Violence and unrest sparked by tensions between ethnic and religious communities occur in various parts of the country and have resulted in numerous deaths. The military may intervene and curfews may be imposed. Canadians should always maintain a high level of security awareness and inquire about local conditions when travelling in the country.

To be more specific, our final destination was actually Lagos, a crowded and polluted city of some 13 million inhabitants, and a city with the dreadful reputation of having one of the highest crime rates in the world. In fact, the lonely planet guide I picked up heartily recommends it for the “truly masochistic voyager.” And upon reading through several sources of information, it really seemed like it would be wise to avoid, by all counts, practically everything.

To these information nuggets, Nash would quickly rebuttal. “This is all nonsense. Do not worry about such propaganda. Nigeria is the West African superpower. We have one of the most highly educated workforces in the continent …” And then in the middle of the blur that is his hand gesturing, he would pause and smile, “and we are going to win the World Cup.”

Still, as an educator who teaches pupils and the public alike in the nuances of biology, I wasn’t necessarily swayed by his arguments. A country’s soccer prowess holds little weight in teaching scientists the practical and theoretical aspects of molecular genetics (for instance, I have yet to witness an offside penalty in my lab). But things like reliable power and water sources do matter and, as Kate my wife would so ardently point out, it’s also nice to not worry about things like violence and riots.

* * *

The morning I left for Nigeria was a bit of a somber affair in my homestead. I would be away from my wife and my baby daughter for two and a half long weeks, the first time I was to be away from them as a new parent. This wasn’t really how it was supposed to unfold. Originally, this teaching assignment was scheduled to be held in a previous year, where Hannah would be but a twinkle in our eyes or at the very least, safe in a second trimester haven – both situations that wouldn’t have yet revealed the emotional enormity of fatherhood. It was originally to be an adventure. Even Kate had toyed with the possibility of joining me. However, adventure would now take a secondary role to family life and Kate would join me only in spirit and kind words via a bundle of letters – one for each day of my trip. It seemed that she took to heart the warnings about unreliable telecommunications.

Thankfully, I was not traveling alone. I enlisted the help of Dr. Samantha Greunheid, a post-doctorate and colleague at the University of British Columbia. Sam was a specialist in infectious diseases, which seemed to be a good fit given our destination. She was also knee deep in proteomics, a burgeoning research field that looks at proteins (what the DNA genes code for,) and, for lack of a better description, tries to look at all of them in any given circumstance. For instance, Sam was primarily interested in looking at proteins present in her bacteria, and in particular trying to observe differences between samples that were docile, and samples that were actively involved in an infection. In this respect, proteomics is a newer breed of science that relies heavily on high technology, high throughput and almost steamroller-like tendencies, all the while generating massive amounts of data such that mathematicians and statisticians are being courted into the process. This part of her research would be completely novel to the primitive state of Nigerian science. It was to be a compelling and interesting mix. Most important, however, Sam was down to earth and had an easy low maintenance attitude, which I feared was going to be necessary for this trip.

Before we had even departed on our flight, it became clear that our itinerary was a focal point of some intrigue. I remember the conversation we had in Seattle with one of the immigration officers who examined our visas. It began innocently enough:

“Where are you going?”

“Nigeria.”

Then came a short pause. “Nigeria eh? Why are you going there? Are you missionaries?”

“No, actually, we’re university teachers. We’ll be teaching a science course there.”
Another pause. “Well,.. better you than me.” A sidewise glance, “You know, you may as well say goodbye to your luggage now. Those folks down there, they just take whatever they want.”

* * *

How Lagos, and Nigeria in general came into these troubled circumstances is rather neatly if not bluntly explained in the book “The World’s Most Dangerous Places,” a Christmas gift given to me by my not so subtle parents. In it, Robert Young Pelton – who could give the Crocodile Hunter a run for his money for pure bravado – provides descriptions and anecdotes for destinations you would best avoid. My worried mother had actually folded down the pages on Nigeria, such that its 3 out of 4 ‘peril rating’ was immediately evident.

In short, Nigeria had for the better part of its 40 year history been subjected to the whims and follies of various military rules. Which together with its diverse cultural mix and its lucrative oil deposits, exacerbated into an unwieldy recipe for political chaos, ethnic tension, and rampant crime. However, even the casual follower of world politics knows that what makes Nigeria especially infamous, is its almost legendary propensity for corrupt practices. In fact, Nigeria has consistently ranked as one of the worst offenders in various Corruption Perception Indexes, and it would probably surprise no-one if its unclean borders were shown under thesaurus entries next to words like corruption, profiteering, racketeering and venality. In general, the whole messy predicament had turned Nigeria into an economic mess that to this day precariously teeters on the strength and weakness of oil prices. From this viewpoint, it is no wonder why the country has had the reputation it garners.

And yet, Nash would consistently reassure us that things were now different. That the country, and even detestable Lagos had its merits, its civility, and its comforts. That since 1999, the country had been mending albeit slowly with the first elected president residing over democratic government. He would tell us that the time was now ripe for science to return to his troubled homeland.

However, truth be told, I wasn’t sure what or who to believe anymore. Frankly, my mind was now more preoccupied with evaluating the worth of my small science workshop. Nigeria, it seemed, had problems that were much bigger than biotechnology.

* * *

Murtala Mohammed International Airport in Lagos seemed to be as good a place as any to feel out the current truths on Nigeria’s reputation. This place was to be our testing ground, a microcosm of sorts, and would provide us with a visceral sense of things to come. In this respect, the airport would be a focal point of a number of things. First up was the task of transporting scientific supplies from Canada into Nigeria. Part of my responsibilities entailed the delivery of some special chemicals that were not readily available in Nigeria. An innocent enough endeavour as these chemicals included relatively obtuse things like ultra pure varieties of water and salt; as well as some more sophisticated reagents like antibodies, DNA molecules, and even live but attenuated bacteria. A few of the tubes even contained samples of fake data which were a teaching lab’s last resort should the experiments go completely awry. All of which were harmless and worthless of course, given that my work centered round educational goals rather than specific research goals. Unfortunately, all of the reagents needed to be kept cold in order to stay happy, which meant packing everything in copious amounts of dry-ice, a problematic venture given dry ice’s hazardous reputation in the transport business. This nuance caused no end of frustration especially since the reason for it being labeled dangerous wasn’t clear to me or, for that matter, to any of my chemistry colleagues.

Nevertheless, it was imperative that these supplies make it to Nigeria. For advice, I contacted Dr. Terry Pearson, a noted parasitologist at the University of Victoria, whom Nash had invited as the keynote speaker for our workshop. Terry, who specializes in Trepanoma research, the causative agent of sleeping sickness, has long had collaborations with various institutes in Kenya and was the person in my neck of the woods to consult on the ins and outs of transporting scientific goods to Africa. Although, we would later formally meet in Nigeria, he was a veritable wealth of information – a Yoda-like antidote to my ignorance.

“Don’t even bother with a courier.” he would tell me, in a gruff friendly manner that perfectly imbues someone equally at home in a state of the art biochemistry lab and in the safaris of southern Kenya. “They’re too damn expensive, and in my opinion, you’ll never see your package again.” He added, “You can try the air cargo route, but I’ve never had much luck with that myself.”
He then went on to explain that the only way to guarantee getting the materials over to Africa would be to simply bring the icebox to the airport and carry it on the airplane myself. “You’ve got to go to the airline agent and suck up big time, hope that they trust you, and let you bring it on. That’s really the best way to do it. The only way to guarantee that you actually get it to your destination. If you want, you can bring all your fancy credentials – it certainly can’t hurt. But at the end of day, it all depends on whose manning the desk, and whether they like the look of you or not.”

It boggled my mind that my best chance in all of this chaos would be to bring the reagents onto the plane myself. Reagents that included among other things, an assortment of scary sounding chemicals, kilos of dry ice, and (get this) live bacterial samples. I shuddered at the thought of trying to explain to airline staff on the harmlessness of the bacteria in the security intense world of post September 11.

Consequently, I thought it pertinent to also give the airmail route a go using either a courier or cargo service. Terry was not kidding. Although the reagent package itself was no bigger than say a stack of 5 compact discs, the process of transport itself due to flight connections, and navigation through various custom ports, meant that the trip would take a minimum of 4 days. Which translated to an awful lot of dry ice to keep things frosty throughout the whole venture. This now heavy package would subsequently amount to a small fortune in shipping costs – to the tune of about US$450 via a company like Federal Express. or a more reasonable but still expensive US$200 using an air cargo service. Still, it was an alternative worth using, and approximately a week before the workshop, I arranged to send package number one into the unknown.

Package number two was safely bundled in one of those squishy ice bags, and packaged with enough dry ice to last for a 16 hour flight. It also came with a wad of paper, large enough to look like a novella, but which actually contained MSDS or materials and safety data sheets for each and every item in the package, as well as photocopies of every official looking letter of intent. The MSDS sheets were considered to be both advantageous and detrimental in our efforts to board the plane. They were the documents required to state the relative hazard level of each chemical, but in reality they often depicted the most harmless of things as being dangerous themselves – after all, even water has a lethal dose. As I approached the airline desk with Sam, it suddenly dawned on me that my chances of getting the package on board the plane would have increased significantly if I had my baby Hannah as a token gesture of innocence. However, in one of those surreal moments where one’s expectations are flogged and hung, we experienced no problems, no lines of questioning, not even a customary look of concern. Neither Canada nor the United States seemed to care about my icebag and my package number two was therefore on its way.

The actual arrival at the airport in Lagos was our second task, and was also an exercise in tension for both Sam and I. Tense, because according to all accounts, personal and otherwise, the airport was the place for peril and quite simply, it was the one part of the trip that we were most worried about. We were repeatedly warned not to converse with anyone that we didn’t recognize, and to not take any mode of transportation without directions from someone we knew. Taxi drivers were notorious for partnering with any number of robbers and bandits, and it was reputed to be a calculated risk to interact with any stranger at the airport. Definitely not the most tourist friendly location I’ve been to. Basically, we were focused on thoughts of getting through without being detained or being robbed. In other words, we were under the uneasy impression that our lives depended on Nash showing up at the airport to be our personal escort.

Surprisingly, customs at Murtala Mohammed International Airport was brief, and my package number two caused no curiosity. In truth, the airport itself, seemed to be relatively quiet, no doubt a consequence of the armada of severe looking armed guards that manned all the key entrances. I could see through the main doors that the roadway outside was populated by a throng of locals, tidily kept behind a number of security fences. This was presumably to clear the main road of congestion, and possibly the riff raff we were told to avoid. For a fleeting moment, we sensed our folly at believing all of the tall tales, which at this point, seemed to be grossly exaggerated. Everything was going smoothly and everything seemed relatively civil.

However, as soon as we picked up our remaining luggage, we were accosted by two persons – a man and a woman – who aggressively asserted themselves as our escorts, and forcibly directed our cart towards the airport exit. Of course, this scared us out of our wits, as the very thing we had been warned about seemed to be happening before our very eyes. Even with our protestations, our new escorts were adamant on leading us into the outside throng.

Thankfully, before we ended up causing a minor scene, and likely one with the participation of armed guards, Nash appeared from the chaos to save us. It would be an understatement of monumental proportions to say that it was a relief to see him in person. We were suddenly empowered with the one criteria required for travel in Lagos – that is, a friendly face.
Boarding into a van, we soon found out that our two headstrong escorts were indeed official members of our host institution, the University of Lagos. In no small way, the whole incident clearly showed us the destructive power of heresy. Looking back, it’s still hard for me to pinpoint whether our feelings of panic were attributed to information we had been given, or to the situation itself.

As we began to move, I immediately sensed a grimness in Nash’s demeanor. He was not as animated as usual. When confronted he said, “The lab is below my expectations. The Local Organizing Committee has done a very terrible job of this.” I, ever the optimist, bounced back, “Well, at least package number two made it through.” I clutched the ice bag as if it was the most important thing in the world. “How did package number one fare?” I asked.

“It is here.” he replied curtly, “but I cannot get it without paying a customs fee.” When I explained to him that I explicitly made it clear in all the documentation that the materials were not of any worth, he just smiled at me and said, “Welcome to Nigeria.”

* * *

Bribery, or dashing, as it is affectionately called in Nigeria, is a national pastime second only perhaps to soccer. Nash would explain to me that the airport authority controlling our cargo had asked for a flat fee of 30,000 Naira, which was roughly equivalent to US$300. A tidy sum of money that is no less than a small personal fortune in Nigerian standards. Of course, Nash, ever the pragmatic individual, flatly refused to pay. Over the next two weeks, we recieved daily updates on the current amount of dash needed to relinquish the package. On the last day, the bid fell to 5,000 Naira – to which Nash responded, “Send it back to Canada.”

As predicted, our rendezvous at the airport provided a window to Nigerian life in the here and now. Sam and I both agreed that in hindsight, a lot of the apprehension we carried was a consequence of distorted information. What we saw instead, was a nation in transition, going from bad to not-so-bad (albeit slowly), and a culture that was as foreign as any other to the serious traveler.

It was when our van took us through the harrowed and crowded streets of downtown Lagos, that the full brunt of culture shock finally hit. Peering through the windows of our vehicle, we saw a completely different way of life – primitive, at times decrepid, and altogether frightening. The heat of the night seemed to mix well with the incessant dust and ramshackle nature of each and every building we saw. These sights made us instinctively think of home and so our first order of business was to look for an internet cafe. This was to qualm the fears of our loved ones with a friendly and reassuring message of “I’m in Lagos and go figure, I’m safe and sound.” Then a welcome stop for food. I think Nash was trying his best to make us feel comfortable since he took us to a ‘Mr. Biggs’, which was more or less a clone of the MacDonald’s variety, except with burly armed guards. As I ate, I found it decidedly ironic that the first meal I had on this exotic adventure was a hamburger and fries.

Nash then took us to our accommodations. We were staying at the University of Lagos Guest House which was more a hotel than a student residence and was considered luxurious at a cost of about US$40 a night. Although my own room was fairly large, this did little to obscure its general disheveled state. Despite this first impression, I counted my blessings since the room actually had reliable power in the form of a back-up generator, working air conditioning, a toilet (sort of), and a television with 5 channels (curiously, three of which were set to MTV). It even had malarial pest control in the form of staff spraying the room each night with a can of Raid, and it also came with a comforting set of door locks. In any event, it would more than suffice and I gladly dropped off my backpack, and then queried Nash for a good place to stash the contents of my ice bag.

Although we were very tired, Nash said that the best place would be in a scientific freezer, and that we should see the lab facilities immediately. The sense of urgency and the fact that he continued to look sullen was troubling to say the least. Here was the eternal optimist reduced to a stoic figure. I was thinking, “how bad could it be?” We had, after all, been corresponding with the Local Organizing Committee for several months, and according to all the pertinent check lists everything appeared to be sound. Everything should have been ready and waiting, and the only possible shortfalls we had to worry about, were the chemicals and reagents in my package number two.

* * *

The Local Organizing Committee or the L.O.C. for short was a group of scientists, and university representatives who were responsible for providing us the necessary facilities and equipment required for the laboratory workshop. However, it was clear upon first glance of our adopted lab space that the L.O.C. really had no apparent skill in organizing anything. To begin with, our allotted space was not even in the university campus but was instead situated several kilometres away at the Nigerian Institute of Medical Research (N.I.M.R.). Although this distance itself didn’t sound so bad, the additional need to travel by car was very awkward given that the streets of Lagos consistently imbued a state of pandemonium. There was even a colloquial term for the act of driving – a very appropriate “go slow.”

When we approached the iron gates of the N.I.M.R. compound, it was evident that the entire area was caught in the grips of a power outage. In the somber light of our vehicle’s headlights, we drove further into the maze of buildings and stopped in front of a rather unpresuming looking wall. Then following flashlight beams, we were guided like airplanes up a flight of stairs and into a room that looked gutted, disorderly, and plain filthy. “This is our space,” Nash said matter of factly.

In short, the space was horrendous, and dirty to the point that sterility would be pure fiction. In addition, the emergency generator backing our area was ranked somewhere between sub-par and non-existent, which meant that loss of power was a real consideration. However, this concern was soon countered with the realization that we were given next to no equipment to run our experiments anyway.

As we blew off the dust from the one solitary bench in the room, I was drawn to one of three conclusions. One, that Nigerian science had deteriorated to such an extreme that even a campus that boasted a student population of 30,000 students and connections with over 100 other Nigerian Universities, could not muster up enough basic equipment for 12 experimental stations. Two, perhaps Nash had been misleading us all along with respect to his country’s resources. Or three, maybe all of those tall tales were not so tall after all.

The following morning was spent contemplating the Guest House breakfast menu, which basically consisted of eggs and toast, toast and eggs, eggs alone, or toast alone. The poor selection of items mirrored our facility and equipment status. Consequently, our second day in Nigeria would primarily concern itself with sorting these problems out and we would try to do this at the opening ceremony. Here, we would have the opportunity to meet face to face with some of the members of the L.O.C.. and voice our concerns. Unfortunately, it soon became very clear that the L.O.C. were largely indifferent. Instead, most of the members were more interested in garnering attention by using the ceremony as a chance to exhibit their skills in speech making. We did, however, have a few sympathetic ears – individuals who were quite apologetic about the whole situation and tried to explain that the lack of resources was a pressing reflection of the financial hardships within the research community. Not so much that the equipment didn’t exist, but rather that the equipment was such a precious commodity that the distinction between the haves and the have nots was zealously guarded. In Nigeria, the notion of collaboration was swept under rugs, in favour of concealment and selfishness.

In retrospect, this reality was already evident, given our experience with transporting reagents. If securing a small shipment of chemicals had cost me several hundred dollars in transportation and “custom” fees, then what hope was there for the average Nigerian biologist. This was beginning to look less and less like a workshop on molecular techniques, and more and more like a Survivor episode for science geeks.

Fortunately, due to my background as a Boy Scout and an inbred predisposition to being prepared, I had taken every tall tale I heard in Canada to heart and had pretty much prepared for any and all contingencies. So after the opening ceremony, Sam and I immediately went to work assessing the general status of the workshop. To begin with, the sparse supply of equipment necessitated a change in how the students would work together. Nash had originally arranged for enough chemicals so that a class of 24 students could be split into 12 working pairs. However, the equipment that was given to us by the L.O.C. would limit us to only 3 working groups – each with 8 students, which was hardly optimal. Nash was especially angry with this nuance and even went so far as to accuse the L.O.C. of arranging this on purpose so that the excess reagents could be scavenged for personal use.

Even the equipment we did have was suspect at best. For example, the lab was supplied with one centrifuge that worked in a quirky fashion. This machine to the uninitiated is a device that contains a rotor capable of spinning around at high speeds. The net effect of this action is the creation of centrifugal force – the type of force that makes water stay within a swinging bucket. In essence, this machine speeds up the ability to separate constituents within a mixture according to density. For instance, a mixture of sand and water would result in a sand pellet at the bottom of a tube with the fluid on top. Anyhow, our centrifuge worked like a charm except that the lid wouldn’t open unless you turned the machine upside down, which was a really aggravating feature since our separated samples would simply become mixed up again.

We were also in dire need of a Polymerase Chain Reaction machine or P.C.R. machine for short. This device essentially allows an experimenter to amplify DNA molecules such that you can have a billion fold increase of material to work with. In short, this makes it easier to observe and characterize DNA molecules, especially when the initial amount is very small. To the layman, P.C.R. was the token technique described in Jurassic Park. Although, not actually powerful enough to clone dinosaurs, its overall utility is such that this is the machine of choice for a number of key experiments such as DNA fingerprinting, DNA sequencing and any technique devised to look for specific genes. All in all, about a quarter of the procedures in the workshop syllabus would rely on this one piece of machinery. Frustratingly, the L.O.C. had actually provided us with a machine to use, but only after politely telling us that it was broken.

We had heard through the grapevine that the N.I.M.R. compound actually had a brand new P.C.R. machine, and soon found out that the device itself was only a few hundred feet away from our own disordered facilities. This adjacent building turned out to be a newly built structure with the explicit purpose of conducting research on the human immunodeficiency virus, the causative agent of AIDS. Funded by the Bill Gates Foundation, it was exactly the sort of space that our workshop should’ve been offered in that it was clean, it was fully equipped, it had reliable power, and from first sight, it even appeared to be underutilized. I immediately cursed my luck for it being a centre for HIV research since this would imply strict procedural rules that would make it next to impossible to borrow the entire facility itself – HIV is after all a hazardous organism. However, I saw no problem with the use of its PCR machine given that our samples were essentially benign and had no chance of jeopardizing any of the HIV work.

So all in all, pressing on with the workshop presented itself as a formidable task, and it was decided that clear objectives needed to be tackled. I would begin by assessing a general flowchart of how the lab would run, taking into account all of the possible shortfalls along the way. Sam would visit working internet to see if she could find information on ways we could cheat or MacGyver our way through certain procedures – essentially finding procedural tricks that would enable us to perform the experiments without the luxury of certain scientific supplies. And Nash would see about getting us permission and access to the Bill Gates’ PCR apparatus. Taken together, it was clear that we would need some extra time before the lab was ready, so in order to stall, we announced that the first day of the workshop would be limited to a full day of lectures.

* * *

Meeting the students changed everything. In contrast to the wallowing apathy of the organizing committee, these young faces were a breath of fresh air. Although, it was a grueling first day of work where my time was spent rooted in front of a small blackboard, it was enlightening due to the enthusiasm of the young crowd. In light of all the hardships that this country faced, it was evident that the Nigerian youth took its education seriously. This was further espoused by the country’s willingness to grant access to university level education based on free will alone. Despite this positive outlook, it was discouraging to ponder the future of bright individuals who appeared focused, willing to learn, and yet realistic in what outcome this workshop could bring. You also had students who naively embraced the hope that the workshop would literally change their views on science, and unquestionably lead to a better life. And of course, in a society such as this, we were not surprised by personalities who were desperate to leave the country, and simply viewed Sam and I with the ambitious and tenacious intent of a possible ticket out.

I paid careful attention to each of the student’s attributes, because Nash had vested in me the responsibility of selecting the four most promising individuals. These four would then benefit from Nash’s personal attention in mentoring and guidance. I took this decision very seriously because I really felt that being one of the chosen would result in a dramatic improvement in life itself.

All told, the practical sessions ran for two weeks and constituted a flash pan of memories. It was a session like no other, where each day brought a different obstacle to the mix, and like any challenge, there were notable ups and downs. The lab began in an interesting enough fashion with a brief visit from Dr. Emmanuel Denenu – a messenger from the Federal government and an unfortunate scapegoat for the frustration that must greet these students day in and day out. Although he came to discuss the future, opinions about the present took centre stage and the fire in the student’s voices during this confrontation would continue to ring in my ears for the rest of the workshop.

On many occasions, my heart sank as I began to second guess the value of the workshop. Sometimes, it seemed all too silly to be coming to a place such as this, to teach something as absurd as molecular biology. These pangs of doubt were constantly highlighted by the looks of disappointment on the student’s faces whenever it became all too clear that the chemicals and reagents that I lectured about, were simply not feasible in a country with corrupt shipping practices and freezers that were forcibly useless. How could one talk of delicate molecules, when we even had difficulty getting something as benign as chalk! (At one point, Nash would have to purchase some himself since the L.O.C. would refuse to help).

There was also a disturbing sense of innocence and a dangerous level of ignorance about the science in general. The students were often unrealistic in their assessment on what these genetic techniques could accomplish and how fast they could be performed. There were many instances where the idea of genetic modification was nonchalantly chosen as the be all and end all to experimental design. Many of the student presentations we heard would conclude with a simple “I would make this and that better by genetically modifying it.” This eagerness to so readily adopt the use of molecular biology was troubling to say the least. In our own developed society, there is a general theme of caution applied to any scientific endeavour, and it was important that these students understood the possible ramifications and considered the ethical arguments behind the use of such technology.

We spent a fair amount of time deliberating these issues, and it was interesting to hear the musings and opinions of Nigerian students. Suffice to say, opinion was mixed in that whilst all agreed with the general intention of being ethically sound, several suggested that the barrage of ethical polemic was a western luxury – that only for countries as rich as Canada or the United States, which reflected a high degree of stability, was wasting valuable time and money arguing over the pros and cons of a technology acceptable. This was certainly food for thought.

As a whole, teaching conditions remained pretty primitive in that the equipment and facility dilemma never really sorted itself out. Still, we could boast a few tangible victories. For instance, we were able to secure access to the Bill Gates PCR machine, although this achievement took a little maneuvering and involved a fortuitous meeting with the director of the N.I.M.R. facility over coffee, crackers, and (presumably for public relation reasons) several photographs. We were extremely lucky with our power situation, in that it never directly affected our experimental procedures. Rather, the loss of power tended to conveniently coincide with the lecture components of the course – it was almost uncanny. Most astonishly, we managed to tease success from about two thirds of our experiments, an almost unbelievable statistic that hopefully reflected our skills as instructors, our knowledge of the material, and of course, searing blind luck. In truth, we did have to resort to our “fake” data stash, but only once. It’s also safe to assume that there are now 24 Nigerian students who are quietly pondering the identity of this MacGyver fellow that Sam and I kept talking about.

The intangible victories were a little harder to ascertain. Apart from the empirical act of teaching new material, I hope we were able to leave the students with a strong sense of what we thought was wrong with Nigerian science. That is the prevailing acceptance of the harsh but understandable ‘every man for himself’ attitude. For us, this philosophy was painfully evident from the very beginning in the effort required to get any help whatsoever. In our minds, this selfishness was shattering any hope of allowing Nigerian science to flourish. In simple terms, here we had a well educated society that was stifling under limited resources – it simply made more sense to us to foster collaboration, to rely and build on each other strengths, and to share valuable resources.

We also left behind a small legacy of embarrassment. Our negative experience with the Local Organizing Committee and with the University of Lagos, in general, bequeathed a lasting impression on the Federal Ministry of Science and Technology. Dr. Denenu was obviously disappointed with the behaviour of the L.O.C. In the interim, it seemed that more than a few eyebrows were raised during our workshop, and Nash consequently earned the right to formally interact with the government in all future programs. One can only hope that this will lead to better things.

Fittingly, the last day presented itself with two dominant and opposing memories. In an amusing turn of events, Nash and I were presented with a bill for various charges. It was stunning to us that the L.O.C. would have the audacity to ply us for even more money. The bill itself was a mockery with money attributed to items like extringencies, which, to this day, is one of the great mysteries of the workshop. To be perfectly honest, no-one was even sure what the word meant. Nash took care of the bill in his own special way, which is to say that he probably threw it away.

The other memory was that of the students huddled together in a welcoming circle, holding hands and saying a small prayer.

“Thank you lord for your generosity in life, that you hold together our faith in you, and that you provide what you can in our lives. Thank you for the opportunity in allowing us to attend this molecular biology workshop, that we might take what we have learnt to help our people and country in need. That we use it responsibly and with respect to our land. We ask that you guide us in shaping a better future. That you guide us in the spirit of collaboration. That you help us all of us stay true to this aim and to deny the spirit of selfishness. We asked this in the name of the Father, the Son and the Holy Spirit, Amen.”

This is going to sound cliched but the workshop, and I suppose the whole experience itself, made me reflect on my own lot in life. I would be fooling everyone if I didn’t comment that during each day of our laboratory and lecturing sessions, I felt a strong sense of relief and gratitude. Relief in that at the end of it all, I actually had the option of leaving it all behind. Gratitude because through some cosmic roll of the die, I was born in a country where food, shelter, and indeed a decent way of life were readily available. We really take too much for granted.

Today, Nigeria like most of my memories is slowly fading from my mind, in this case buried by the security of my own family and kept alive only in souvenir status by the occasion headlines that skim my consciousness. Where indeed does science fit in a country that is on the one hand dogged by controversy over Amina Lawal, a woman sentenced to lethal stoning by a Sharia judge; whilst on the other hand prepares for the Miss World pageant? Next time I talk to Nash, I’m going to have to ask him. Turns out, Nigeria didn’t win the World Cup that year, but then again I suppose there’s always next time.

Making cloud chambers for elementary school kids (and anyone else who would appreciate epic DIY science).

In about a week from now, my lab’s Science Creative Literacy Symposia fieldtrip will begin a new season in earnest. Here, I’ve got a great mix of science grad students, and creative writing MFA’s coming together to design fieldtrips, all in an attempt to highlight the fact that mixing science with creative writing isn’t such a strange thing after all.

The first session will host a Grade 5/6 class, where kids will explore the basic theme of “invisible things.” To do this, the science experiment that has been lined up involves making a DIY cloud chamber – fully capable of picking up contrails from the activity of sub-atomic particles (I know… so awesome!).

I think this is just about the perfect sort of thing to broach the subject of things that are “invisible,” and as a nice touch, I believe the grad students may go about this fieldtrip without giving the kids a heads up on what they might see (i.e. they’re aiming for that wonderful feeling of surprise and elation with discovering something unexpected – “Whoa! What was that!”).

The methodology, itself, can be found in various places on the net, but this here below is a really nicely done YouTube video on the matter, which we’ve used as the basic template.

Still, like a lot of things on YouTube, there are often details that are missing which may actually be quite important. More so, if the intent is to get a class of 11 year olds to make 12 of these things that have to work in a somewhat reliable and safe fashion.

Anyway, apart from a dark room, here are the basic supplies needed:

- – -

DIYcloudchamber01

- – -

There’s a couple key things that I can point out here. Firstly, the tin foil pie plate is essentially the base that will be made cold (with the dry ice), so as to create a temperature gradient, which in turn is responsible for producing an isopropanol cloud. As such, there’s a few important things it needs:

1. You need isopropanol, which is actually quite easy to get (look for the 99% rubbing alcohol in your local pharmacy). Dry ice on the other hand is sometimes tricky to get (in Canada for instance, there are official rules for its transportation).

2. It needs to be of a colour that allows you to see an isopropanol droplet cloud easily. Most videos seem to suggest something with a black surface, but this isn’t always easy to find, and possibly expensive if you need 12 of them. We’ve tried pie plates that were silver/grey (usually the most common) and red in colour (red was really difficult to observe), but the tin foil variety actually worked really well. This seems partly because it’s able to reflect the incoming flashlight, so that you can control the angle of light (just so) and in a way to best see this cloud.

3. It needs to be deep enough to encase a sufficient enough amount of dry ice, so as to more effectively maintain that cold temperature gradient. Here, we tested plates that were about 1/2 inch deep versus 1 inch deep, and the 1 inch variety worked much better. Presumably, it would also work if you just sat a thin sheet of metal right on top of a dry ice block (we were using pellets).

4. It needs to be of a material that best transfers the coldness of the dry ice to the rest of the chamber. This is why metal is often suggested, but the tin foil was just about perfect here. It’s metal, but it’s also very thin. I noted that the chamber got cold very quickly and reliably.

A second piece of equipment that needs mentioning, is the plastic cup. You can use glass, but the plastic cup works just as beautifully. Don’t forget that it has to be small enough to create a supersaturation situation, and it’s true (as the video suggested), that the smaller it is, the quicker you can see results. If possible, try to get cups without ridges so that there’s no obstructions to the observations.

Anyway, when you put it together, it’ll look a little like this:

- – -

DIYcloudchamber02

- – -

There’s a few key points here as well:

1. Having enough isopropanol in the system seems to be important. In this set up (with a 250ml cup) there seemed to be a big different in what we saw when there was 10ml versus 15ml of isopropanol in the system: in a nutshell, the 15ml generated a lot more visible activity (might be worth trying 20ml on the day of).

2. Concurrently, this also means you need something capable of absorbing a decent about of the alcohol, so that it’s not drippy. The video mentioned using a piece of felt, but a clipping from a “super absorbent auto sponge” worked much better (it was also a lot easier to anchor to the roof of the cup).

3. This part is IMPORTANT. The seal between the cup (after the sponge and isopropanol steps are done) and the tin foil pie plate must be completely airtight. This is why plasticine is such a great idea! As well, you should do this before any of the cooling steps, since the cooling will simply condensate water onto anything and everything, making surfaces wet and difficult to work with. I suggest putting together the cloud chamber in the following order:

(i) Construct cup + sponge + plasticine + isopropanol + tin foil pie plate” contraption. NOTE: add the isopropanol into the cup (directly on the sponge) immediately before sealing the system with plasticine. This minimizes the amount of isopropanol fumes hitting the air. In the same vein, direct handling of isopropanol is best done by an adult, and in our case, we’ll get the kids to do the sealing but will supply them with gloves (partly as a precaution, and partly because kids just like wearing gloves in a science lab) – full safety details can be found here and here (MSDS) (Thanks Dave).

(ii) Move these contraptions to your dark room (if you’re not already in it – we’ll be using a windowless lecture hall for instance).

(iii) Flip the contraptions upside down, so that the empty pie plate is now on top, AND THEN load the dry ice. (Here, of course, you’ll need to flip the whole thing upright again, so that the sponge is back on top with the dry ice at the bottom encased in the upside down pie plate – we’re going to do this with the base of an ice bucket but some sort of cold resistant matt should also work well). NOTE that dry ice should also be handled by an adult as prolonged contact can cause frostbite – see here for MSDS.

(iv) Then turn the lights off, and use your flashlight to shine a beam of light in such a way as to see that droplet cloud (looks a little like a miniature snow storm), and then, well…, then you wait. You should see something within a few minutes, but it definitely helps to be patient here.

Anyway, I’ll report back after we’ve done this, and let you know how it went with the kids. As a heads up, the creative writing portion will involve writing and acting out mini screenplays – I can’t wait!
