It's been on the back of my mind for the last week or so to work through the science-on-stage booklets to see if they contain a few ideas that might (safely) be repurposed from classroom demonstrations to at-home-challenges.
One example that I think might work is to set students the challenge of replicating the scenario shown here, and to share the result via a photo (maybe using a bit of timber instead of a metre stick)...
Or perhaps a video of what follows when they try this...
Perhaps I'm being over-ambitious, given that the tech-savvy digital natives that I work with can't even persuaded to submit their work in portrait rather than landscape mode, but I'm going to give this a go. I'll report back on how well/not well it goes...
Either way, the science-on-stage booklets contain dozens - or possibly hundreds - of great ideas. All available at http://www.scienceonstage.ie/resources/
