- What's Old is New Again, Right? The classics all made appearances. Fruit batteries, and kitchen sponges teeming with bacteria. "Green" cleaners, iron in breakfast cereal, and tooth-dissolving cola. And, of course, what would a Science Fair be without a baking soda volcano?
[Sadly, a fellow judge clued me in to a site that helps students, even those who start the night before, to quickly assemble a project, 'data' and 'writeup' included. Sigh.]
- TV Infiltration: Scientific 'reality shows' and crime scenes both figured prominently. Future forensic teams examined simulated blood spills with luminol, tested decomposition rates of flesh in various soils, and dusted for fingerprints. The Mythbusters might have enjoyed this fair; urban legends on display included fruit spoilage, fridge doors, car engines, memory tricks, and clothing stains.
- Back When I Was Your Age...Amazing to see how "high-tech" projects have trickled down into lower age groups. I watched third-graders isolating DNA, middle schoolers playing with Green Fluorescent Protein (GFP), and young adults - who couldn't yet drive cars - genetically engineering algae!
- Funny Titles: Double entendres and in-jokes won the day. On notice: a windmill project ("Who Broke Wind?"), a microbe digester ("Poop Power"), and a chromatography project ("Solvent Battles!").
All in all, it was a great experience, and I recommend all readers volunteer when the opportunity arises!
