Episode description
This episode is all about lava! Our guest Genna Chiaro walks us through different types of lava flows, the kinds of rock they form, and how the stories of ancient people often reveal the scientific truths of the land in interesting ways. Plus, we break down our song "The Aa Aa Pahoehoe Lava Rock Walk" one instrument at a time.
We also introduce the Dr. Evil test for magma! (It's simple, Scott, really it is.)
Onward!!!
