Modeling Elastic Rebound: The Earthquake Machine Lite

Description

In this activity students explore a mechanical model of a fault to teach how energy is stored elastically in rocks and released suddenly as an earthquake.

Audience

Grades 5 to 12

Time

45 to 50 Minutes

Objective

  1. Define earthquakes and model their occurrence using the earthquake machine.
  2. Describe the role of inquiry in the process of science.
  3. Give examples of why models are important in science
  4. Develop necessary understanding of the Earthquake Machine to allow future exploration.
