Students discover the differences between P- and S-waves using a slinky. They see that when displacement occurs along a fault, the built up strain of energy is released in the form of seismic waves.

Ninth graders are introduced to the components of compressional and transverse. They practice answering speed problems involving different mediums that waves travel trhough and then review the wave PowerPoint. They then visit physics...

Students explore the Earth's movements by completing worksheets. In this plate tectonics lesson, students define such natural disasters as volcanoes, earthquakes, tsunamis and mudslides and discuss their connections to plate tectonics....
