Sixty Symbols
I've just discovered this set of videos entitled sixty symbols from Nottingham University. I've seen their series on the periodic table but hadn't seen the physics series before. They don't contain any special effects or simulations just experts talking about physics. I don't think students would find them particularly engaging but they are great for reinforcing our own ideas before going into class. I've started linked some of the relevant ones to the Scheme of work pages. Here is one on charge, I want one of those Van der Graaf generators for kids. I have found them for sale on eBay, they are called "Fly stick Van der Graaf levitation wands".
