Brrrrrraaaaa! The alarm clock awakens you. Do you leap out of bed already in high gear, or do you bury your head under the pillow and return to sleep? No matter what you do, you’re using energy.
Scientists define energy as the ability to get work done, whether you’re breathing, giving a party, building a pyramid, or even taking a nap. But where is energy? You can’t touch it, but you can certainly see and hear its results.
There is energy in the sounds and images your television produces, in the fuel that powers the vehicles that deliver you to different destinations, and in the electricity that runs the gadgets and machines you use. There is energy in wind, in waves, in sunlight, and in streams and rivers. There is definitely energy in you—and in every other living thing, whether animal or vegetable. There is even energy in a slingshot when you stretch the elastic strap to its limit and then release it.
So what exactly is this thing called energy, and where does it come from? Sit back, relax, and conserve your own energy, as Kids Discover answers these questions and more about the fascinating world of energy.
