Density of Rocks

Given a variety of rocks, junior geologists calculate densities and correlate them to Earth's layers. As a simulation of continental crust, they experiment with how materials of differing density float in water. Finally, they compare the heating and cooling of solids and liquids and deduct from the results that oceans and lakes buffer nearby land temperatures. These four fabulous activities are useful for introducing learners to characteristics of Earth's solid crust.
