Students learn about the structure of the earth and how an earthquake happens. In one activity, students make a model of the earth including all of its layers. In a teacher-led demonstration, students learn about continental drift. In...

Students work in small groups to use a physical model, the earthquake machine, to examine the occurrence of earthquakes and the inputs and outputs of fault systems.

Students examine images of faults and folds, then experiment with two models to collect evidence to determine how the structures formed.

Animation of the single-block "Earthquake Machine" model shows how "Forces, Faults, and Friction" interact. [0:16]

In this activity, students are introduced to faults. They will learn about different kinds of faults and understand their relationship to earthquakes. The students will build cardboard models of the three different types of faults as...

Students are introduced to our planet's structure and its dynamic system of natural forces through an examination of the natural hazards of earthquakes, volcanoes, landslides, tsunamis, floods and tornados, as well as avalanches, fires,...
