In this activity students discover that earthquakes are among Earth's most spectacular natural phenomena and that in understanding what causes earthquakes we can use earthquake or seismic waves to learn about Earth's interior. Students also learn the other aspects of seismology (the study of earthquakes), which are important parts of any Earth Science program. Students will also learn more about how ... Full description.

This activity uses food to demonstrate plate tectonic motions. Students construct a model using different snacks, which represent various parts of the Earth. For example, frosting represents the asthenosphere, fruit rollups are the Earth's plates, and graham crackers are meant to be the Earth's crust. Students learn how tectonic plates (lithosphere) ride atop the slow flowing asthenosphere layer, ... Full description.

This teacher's guide and activity uses a paper model to teach students about sea-floor spreading and the evolution of oceanic crust. It includes background information for teachers about plate boundaries, ocean floor features, and Earth's magnetic field, as well as procedures, materials needed, and discussion questions.
