Density Experiments & Lesson Materials

Density

Our density sets are perfect for graphing activities. Density Cubes are extra large (25 mm) cubes of 6 different metals: aluminum, brass, copper, iron, lead, and zinc. We have 1-liter bottles and the perfect ballast nuts and plastic pipets for making terrific Cartesian divers every time. Real Japanese 1 Yen coins are made from aluminum and can be made to float on the surface of a cup of water. We have super dense wood that sinks in water. Powered by baking powder, the Diving Submarine dives and surfaces just like a real submarine.
