Men need things from the earth. They take sand from the top of the ground. They pry up big rocks. They dig deep to find metals like gold and copper and iron.

Sand is used to make concrete and glass. Rocks are cut into blocks for buildings. Metals from the ground become bridges, and railroads, and money.

Scientists look in the earth to find things that men can use. You can study the earth like a scientist by doing the experiments in this book.
