Energy is the ability to do work. Energy allows movement in
our surroundings. Without energy nothing would move. All living things need
energy. Plants need energy to grow and reproduce. Computers and televisions also
need energy to operate. People depend on energy to cook food, heat homes, light
streets, and run machines.
Energy is all around us. The sunlight, moving wind and moving
water have energy. Energy can change from one form to another. Without energy
plants cannot grow, animals cannot move and machines do not work.
Energy makes changes; it does things for us. It moves cars
along the road and boats over the water. It bakes a cake in the oven and keeps
ice frozen in the freezer. It plays our favorite songs on the radio and lights
our homes. Energy makes our bodies grow and allows our minds to think.
