What is the World Made Of?: All About Solids, Liquids, and Gases

"What is the World Made Of?: All About Solids, Liquids, and Gases" is a Let's Read-and-
Find-Out Science Stage 2 picture book by Kathleen Weidner Zoehfeld.

This picture book describes the three types of matter, solids, liquids, and gases.

"Walls and blocks and socks are SOLIDS. Milk and lemonade and water are LIQUIDS. The air you breathe is a GAS. Some solids are hard and some are soft. But all solids hold their shape unless you do something to change them. A wooden block is hard. You can push it and pull it and squeeze it -- it will always stay squared. If your baby brother pounds it with his toy truck, it may chip or break. But then the broken pieces will hold their shape."

One other example that is used to describe the three states of matter is water. You can easily follow along with the descriptions in the book by experimenting with freezing and boiling water to watch the changes.

"Can you imagine a world where your toys melt when it gets too hot? Where the walls of your house turn into hazy gas, and animals just walk in and out as they please? A place where, on cold days, you have to swim through the air, and where everything you'd like to drink is hard as a block? What a crazy world it would be!"
