Science projects for kids

Answer 1

A good one for air pressure in physics is to do an experiment circus where they are in pairs and go around the classroom trying out up to 5 different experiments. One is filling a coke can a third full of water, then heating until steam rises from the can and then using a clamp turn it upside down and into a basin of cold water. Watch the can be crushed by the difference in pressure. Another is filling a plastic cup full of water and placing a piece of card on top then turn the cup upside down and the card will stick. Then, you could try and pull apart two hemispheres in a vacuum.
