What is Density?

Curated and Reviewed by Lesson Planet

Density: the reason a giant pumpkin will float, but a tiny cranberry won't. Lesson begins with a demonstration of two of the same-sized cubes having different densities. Then pupils take eight cubes, each of the same size, and have to find their mass and density. They use this knowledge to guess what molecule each is made from.
