This 3-in-1 hands-on set lets students explore the world of earth science, becoming a meteorologist, chemist, and volcanologist in one set. Students mix solids and liquids to create gas, a bouncy ball, and goop. Then they can make a weather station with a barometer, wind vane, rain gauge, and thermometer. Or they can watch raisins dance and feel real pumice. Finally, they can build a volcano and finish this set with an eruption that young scientists will want to do over and over.
