When planets begin to melt, the materials in them begin to separate from one another. The heaviest materials, such as metallic iron, sink to form cores. Low-density magmas rise, forming crusts. This process is called differentiation. In this activity, students will simulate differentiation using pennies, sand, water and toothpicks.
