Hello, I took EE at University.. working on my master's right now (advanced control for electric power steering system). Kind of wanted to always teach, and here in Ontario, teachers are paid fairly well. Plus I can teach math / senior math as well as physics. Anyway, looking at the Ontario curriculum, it's different in what I was taught, in that more experiments/ demos are to be carried out to demonstrate concepts. I've already talked to one of the local school's physics teachers to see how he runs things. I'd certainly like to use a dc motor to illustrate the electrical and magnetic concepts, as I work with those quite frequently in my research. I figure the famous Newtonian prism (also the Pink Floyd logo) would be great for backing up Snell's Laws, colour, etc. Anyone else on these forums teach physics (either at high school or 1st year University level) have any tips, or suggestions for experiments that are great for student's understanding basic physics concepts? With my background, I can think of hundreds of experiments for mechanics, energy/power, electricity and magnetism, sound, waves, and light. However, I'd like to hear your guys suggestions, especially, on experiments/demos/videos to demonstrate the basics of relativity and quantum mechanics, as they are covered in 1 of the 5 units Thanks, Medieval.
