Matter

From a flickering candle to an erupting volcano, this guide shows how everything around us fits into the four basic states of matter. It walks readers through the science of how heat and pressure can change solids into liquids, liquids into gases, and even into plasma, using familiar examples like birthday cakes and lava flows. Designed for middle graders, the book presents concepts clearly, helping kids understand that they themselves are made of the same matter that changes all around them.
