Your junior scientist will love The Young Scientists SeriesSet 2. This set is a collection of 3 kits: Kit 4Weather; Kit 5Solids, Liquids and Gases, and Kit 6Volcanoes. These kits make science fun. Your child can mix solids and liquids to create gas, a bouncy ball and goop; make a weather station with a barometer, wind vane, rain gauge, and thermometer, watch raisins dance and feel real pumice. The journey continues with building a volcano and finishing this set with an eruption that your child will want to repeat again and again.
