"How matter behaves depends on its state. Whether something is a solid, liquid, or gas can change how it may respond to outside forces, including temperature. This topic might seem complicated to some, but in this book, the states of matter are explained through fun, relatable examples and diagrams to reinforce science curriculum content. Hands-on experiments featuring equipment readers can find around the house allow them to apply their knowledge to the topic right away. Straightforward explanations of key concepts and terms will serve them well as they answer quiz questions and riddles throughout the book and in the classroom."
