Demonstrate the inverse relationship between density and volume.

• Set of 5 metal cubes includes: Copper, Aluminum, Zinc, Iron, and Brass
• Each cube weighs 20 g

Equal mass density sets provide an interesting counterpoint to traditional equal volume sets. Students must consider that objects with the same amount of matter may occupy different volumes depending on their density. This equal mass set also makes a convenient comparison of other intensive physical properties, such as specific heat.
