Demonstrating Physics: Electrostatics
In this programme, from Teachers TV, David Richardson from the Institute of Physics continues with more physics experiments for the staff at St. James Catholic High School in London.
Head of biology Wendy Butler has always been afraid of using the Van de Graaff Generator. David shows her how to use it dramatically and safely. We then see her demonstrate it to her Year Eleven group.
David also shows some other striking experiments, including using a microwave oven to light a light bulb. David explains why this happens but is it the kind of demonstration that should be shown to students? Other demonstrations look at air pressure, convection currents, gravity, floating and sinking.
