Modeling Convection Currents
Students learn about the flow of energy and the forces that are thought to drive the movement of Earth’s lithospheric plates. They use a model to discover the conditions necessary for convection to take place, and relate their findings to the flow of energy and resulting movement of matter in Earth’s interior. Students also use a model to learn about the role of gravity in plate motion. This activity provides a formal assessment opportunity for Performance Expectation MS-ESS2-3.
