Set 2 Includes 3 Kits, The Weather Station Kit, The Solids, Liquids, and Gases Kit, and The Volcanoes Kit. With the Weather Station, Young Scientists learn about the weather by making a wind vane to study wind direction, a thermometer to study temperature, a barometer to study change in air pressure, and a rain gauge to measure rainfall. Young Scientists become meteorologists by making their own weather station. Phases of Matter, Young Scientists study the three phases of matter by mixing solids and liquids to create gas, a bouncy ball, and goop. These fun experiments will excite any budding scientist. Volcano, Young Scientists learn about the properties of volcanoes by building a simple volcano and mixing the proper chemicals to make it erupt. This will be an experiment that Young Scientists will want to repeat again and again.
