Density Experiments & Lesson Materials

Density

Our density sets are perfect for graphing activities. Students try to identify each of 12 different samples by determining their density with the Density Identification Set. 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.
