This video segment shows how scientists collaborate to collect and chemically analyze samples of molten lava as part of their quest to learn more about how volcanoes work. Working at Kilauea volcano, scientists collect samples of lava before it has a chance to cool so they can study the chemical properties it had when it was deep within Earth's interior. The samples are sent to a laboratory where other scientists determine their chemical compositions. Questions such as whether two volcanoes share a common magma source can be answered through such analyses. The segment is five minutes forty-seven seconds in length. A background essay and list of discussion questions are also provided.
