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.
Each Explorer’s Library app teaches kids foundational science. Kids learn by playing, experimenting, observing, asking questions, making guesses, and finding answers. We hope each app inspires conversations between you and your kids and sparks more learning in the world around us.
+Freeze soda, pop popcorn, melt gold, and more!

+Explore phase changes and discover which changes cannot be reversed.
+Explore how molecules move at different temperatures.
+Discover which states of matter take the shape of the container they’re in.
+Discover the melting and freezing points of different objects.
+FREE States of Matter Handbook has technology tips and basic info for teachers and parents.
+Interactive text labels in 30+ languages teach vocabulary.
+Aligns with Next Generation Science Standards (NGSS).
+Fun for the whole family — play and learn together.
+No third-party advertising.
