This is the worksheet I use with Bill Nye’s Earth’s Crust DVD. It is a little more in depth than the questions that come with the video, and it gives students something to focus on as they are watching, rather than waiting for the end to try to recall information. As with most of Bill Nye’s DVDs, if you are pressed for time, you can skip the music video at the end. In those, he usually reviews some basic idea, but rarely is new material presented. Between the video, pausing to fill in this worksheet, working with a partner and group after the video, and going over the answers, this is enough to fill an entire class.
In addition to the worksheet, an answer key is also included, so someone not familiar with the material could also lead this activity. If you need additional material, there is also an activity listed separately that covers the bit about how geologists use seismographic records from around the world to support the theory that the Earth’s core is solid.
Feel better soon.
P.S. I rephrased the question about the evidence seismologists used to determine that the Earth's core is solid. It is more complicated than Bill Nye describes. Vibrations can travel through solids, but they are diffracted and reflected, and vibrations travel at different speeds through different densities. The reality is that vibrations are felt across from an earthquake but not at the same strength and intensity expected.
