Heat

In the Heat leveled reader, fundamental science facts in chemistry are explained through simply written text and colorful, fun illustrations. Young readers discover that heat is a form of energy. (The terms energy, work, force, and speed are defined). The movement of atoms and molecules creates heat energy, and the faster atoms and molecules move, the more heat is released. (Atoms and molecules are described.) Ice cubes are cold because the water molecules are moving slowly. As the molecules move faster, the water gets warmer and the ice melts. When molecules move even faster, the water becomes steam. The faster molecules move, the more energy they have. Humans and animals need heat energy to stay alive. A pronunciation guide of scientific terms is included. 24 pages filled with engaging, colorful illustrations. Reading Level 1-3, Interest Level 2-5.
