Earthquake Machine: Demonstration of the 1-Block Model (introduction)

How can you model earthquakes in the classroom?

Mechanical model of the earthquake process using a wood block, sandpaper, and rubber bands to show how "Forces, Faults, and Friction" interact as elastic energy is slowly stored as the rubber back stretches. Then releases an "earthquake when the block overcomes friction. This block-and-sandpaper model can be used to teach the concept of elastic rebound and how energy is stored and released. Earthquakes can provide a useful context for teaching or reviewing many basic physics concepts, such as sliding and static friction, forms of energy and conversion from one form to another, and the elastic properties of different materials.


Keypoints:

  • Block-and-sandpaper model can be used to teach the concept of elastic rebound and how energy is stored and released.
  • The rubber band represents the elastic elements in the Earth
  • Basic physics concepts include sliding and static friction, forms of energy and conversion from one form to another, and the elastic properties of materials.
  • Students can graph the motion and strain

Students collaborate in small groups to investigate how energy is stored elastically in rocks and released suddenly as an earthquake (the earthquake cycle). This activity emphasizes the role of mechanical models in understanding and testing ideas in science.

Lesson Novice

In this activity, students explore of the concept of probability and the distribution of earthquake sizes, and then work to understand how earthquake hazards are described by probabilities. Students then work in small groups to collect and analyze data from a simple physical earthquake model and use online data to investigate and compare the earthquake hazards in California and Missouri.
