Peter is one of those special people who is a finisher. Dissatisfied with the resources available to him in his trainee year, Peter set about creating his own resources. Not only that, he shared them through his web site, sciencedoctor.school.blog. His one problem with all this #sharingiscaring? The endless requests for the answers. If you use the resources and there are no answers, then please send them to him. Thomas says he will put a link to Peter's site on the resources aggregator we host, https://resources.physicsteachingpodcast.com. Peter also suggests ways of spending Jonathan Shaw's £50,000 on Physics equipment - his ideal would be to spend £10,000 on one big ticket item. Thomas is skeptical, Robin delighted. Finally, Peter's Practical in Memoriam is a beautiful way of making one of the less inspiring practicals (density) more appealing.
Friend of the podcast Dave Farmer returns to talk about a subject to strike fear into any physics teacher's heart: uncertainty! We peel away some layers of complexity to reveal... more layers of complexity! Having worked with a lot of exam boards' A-level specs over the last few years, Dave recommends reading the mark schemes and looking for examples of what your particular exam board recommends. Whether we are talking scale resolution, combining uncertainties or ascertaining the gradient of a graph with error bars, we couldn't agree on any of them. But don't despair, there's a lot of uncertainty about uncertainty, so just work out what your exam board require and after that, let your students develop their ideas. We also emphasise that all of these methods are estimations and approximations: rigorous statistical consideration of uncertainty is a scientific career in itself, so inevitably A-level is just going to scratch the surface. Finally we celebrate a physics teaching hero: take a bow Dr Peter Edmunds the Science Doctor who has shared an immense catalogue of resource for physics at all stages. Stuck for some resources? You'll find something on Peter's excellent site - link below. Why not fill your boots and then buy Pete a coffee?
The "new normal" has once again shrunk the globe, as Thomas and Robin reach out to Alberta, Canada to talk to the inspirational Laura Pankratz of the Perimeter Institute. Just as well we talked to her when we did because apparently we've discovered a black hole next door...
