With this kit, kids will learn about plate tectonics by erupting two types of volcanoes to imitate how lava hardens into rock and volcanic mountains grow. Kids can even build a working seismograph to see for themselves how scientists measure earthquake forces. The kit comes with a 32-page book that guides kids through erupting two volcano models, playing a volcano quiz game, assembling a plate tectonics puzzle, constructing a globe, examining real volcanic rocks, and building and using a seismograph.
