All living things need water to survive. But what is water made of and how can it be a liquid, a solid, and a gas? In this book, young students will carry out fun and innovative experiments to learn all about this essential substance. Why does water seem to disappear when it's warmed by sunshine? How does water appear from nowhere on the sides of a cold soda can? And how do rain and snow get up into the sky? From understanding water molecules to discovering evaporation and condensation, budding young scientists will love messing around with water as they ask questions, make observations, gather evidence, test theories, and record their conclusions.
