Geothermal Energy - How can we generate power from heat trapped inside the Earth? Field reporter Peggy Knapp flies to the top of a Hawaiian volcano to explore this question. She discovers that underground pools of molten rock can turn water into steam that can generate electrical power. Your students learn why the Earth is hot inside, how volcanoes form, where they are located, and what geothermal energy is and how it can be used.

Concepts: Volcanoes, energy resources, heat transfer, processes that shape the Earth.

Glaciers - How do massive sheets of ice move over the Earth? Host David Heil goes in, over and around an Alaskan glacier to learn how it was formed and moves. He experiences the massive power of a glacier by coolly examining the trail it left behind. Your students learn what glaciers are, how old they are, where you find them, and what you can learn from them.

Concepts: Erosion, processes that shape the Earth, crystal formation, glacial movement, states of matter.
