Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

Science fair project which determines whether plants are able to get enough nutrients from different types of garbage.

Science fair project which identifies the most effective insulator that you could use to make a winter coat by comparing how well cloth and cotton trap heat.

The buoyant force of water explains why some objects float in water. But why do some objects sink? Find out in this physics experiment and learn about density.
