Description:

The students can see that I am putting energy into the slinky in two different ways. A quick push down the length of the stretched out slinky demonstrates a pressure wave and a quick flip of the wrist will send a shear wave down the slinky. This allows the students to answer questions about why P waves travel faster than S waves. Also, they can see why P waves can travel through a liquid while S waves cannot. I first do the demonstration as described above then they break up into groups to experiment for themselves. I provide one slinky for every 4 students. We then talk about the liquid outer core of the Earth and how this would effect seismograph readings around the globe. Then I give a quiz to help them focus on what they have learned.
