In this fun activity you are going to make a video explaining a physical concept e.g. Work. This is a group activity. If you want to record real examples you will need a camera. If you don"t have one then you will have to make a screen cast.Videos should be about 1 minute long and can include live action, animations, simulations, drawings, you name it.Don"t worry if you can"t do things fast enough, you can speed things...
