Demonstrating Physics: Forces
In this programme, from Teachers TV, David Richardson from the Institute of Physics demonstrate his physics experiments on forces and air pressure. Alongside these demonstrations, we see a teacher testing the experiments out with his Year Seven students. The demonstrations include: • How air pressure can keep water in an upturned beaker. • Ketchup sachets and test tubes acting as Cartesian divers. • The effect of air pressure on marshmallows. • Forces and gravity. • Helium-filled soap bubbles to illustrate floating and sinking.
