Product Information

It's often difficult for young students to distinguish between weight, mass, and volume. This innovative demonstration concretely reveals the differences in these units of measure. Developed by Dave Willey, this soft mass kit allows students to fill bags of equal masses but of different material, and observe how each differs. Kit includes kilogram of marbles, kidney beans, and copper shot as well as two sets of bags in 1 kilogram, 1 pound, and 100 gram sizes, and instructions.
