According to the U.S. Energy Information Administration, energy basically comes in two forms—potential or kinetic. Potential energy is stored energy and the energy of position. Examples of potential energy are chemical, gravitational, mechanical, and nuclear. Kinetic energy is motion. Examples of kinetic energy are electrical, heat, light, motion, and sound. Perhaps the easiest way to introduce these concepts to fifth graders is by using motion to demonstrate the difference between the two forms of energy. Use one or more of these ideas to get the kids in your class excited about science and have fun at the same time.
