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.

Students learn how Newton's Law of Gravitation can be used to determine the mass of the Earth. By calculating mass and volume, they can then determine the Earth's density, and compare that result with the densities of other solar system bodies. Knowledge of Earth's density can also provide information about the planet's interior.
