Andy Darvill's TES stuff

Average Rating5.00
(based on 5 reviews)

I've been teaching science/physics for quite a while, and written lots of stuff along the way. Much of what I've written is for Nelson Thornes, OUP and SamLearning, but here are some things that are properly mine and I can publish here. Hope you find them useful. At www.darvill.clara.net you'll find some more items, and minisites about gcse radioactivity, energy resources and the electromagnetic spectrum which can occupy a class for a whole lesson and more.

A level physics students will probably have a confused notion of where electrons are - something about orbiting…but only in shells…some of the shells can take 2 electrons, others 8… This is a quick explanation of what the terminology means. A level chemistry students often have this as part of their course, so it’s handy for them to refer to as well.
