Solids! Liquids! Gases!

Play with different solids, liquids, and gases. Discover how changes in temperature affect states of matter as you freeze soda, pop popcorn, melt gold, and more! Answer the burning question, “Does it melt?!”
States of Matter is No. 11 in Tinybop’s award-winning Explorer’s Library, a series of apps designed to introduce kids to big ideas. Other Explorer’s Library apps include The Human Body, Plants, Simple Machines, The Earth, Weather, Homes, Skyscrapers, Space, Mammals, and Coral Reef.
