Lesson 4: Seismic Waves
Investigating Seismic Waves
Materials / Preparation
Groups of two for computer investigations
If a computer lab is not available, the teacher can print out the information about waves in step #3 and the instructions for step #4 and then use an LCD projector for step #5.
You should visit and familiarize yourself with all the websites mentioned in this lesson before students use them; the animations can take a few seconds to load. The Earthquakes Laboratory website gives basic information and animations on each of the waves. The Savage Earth animation collection shows different types of faults and how seismic waves travel through the earth. You may want to have your students explore this site as an extension when studying the differences among waves.
