Hi, After several years using TES this is my first post and I am hoping to create a place where we can share simple and effective ideas for teaching Physics. Mainly short demos or pratical ideas that help students visualise what is going on, often with more complex concepts, particularly at KS4 and 5. I find so many teachers have such brilliant ideas that they have devloped over the years but sharing them all, even with in a department, can be time conusming and is often not seen as a priority.I am hoping this will help other Physics teachers as well as myself. Even if you don't think your idea is new or exciting, but is a favourite activity never fails to enagage pupils or help their understanding please post it up here. It is bound to be new to somebody. So to start it off... Induction. Attracting a diet coke can with a charged rod Centre of mass: creating balancing birds andbalancing coke cans on their edge. Lenzes Law: magnet falling through a copper tube and repelling rings Electric motor: Create a large model of a motor out of card, label field lines etc and use the LHR to help pupils see the need for the split ring.
