Density of Earth's Layers
In this activity, students measure the densities of samples of granite, basalt, peridotite/dunite, and an iron meteorite, which are used as representatives of the various layers of the Earth (crust, mantle, core). The samples are weighed to determine their mass, and the Archimedes Principle is used to determine volume. From these two properties, they calculate density, compare it to accepted values presented in the discussion, and answer questions about their observations.
