Publisher's Synopsis
How does flipping a switch on the wall make the lights come on? Where does the clean water that flows out of the faucet come from? What is used to keep a home warm? Travel beyond the walls and under the floors of a house to find out more about the electricity, water, and natural gas that make your home work and find out how you can do your part to save energy and preserve these resources. The inner workings of a home are laid out for kids in fun, retro illustrations jam-packed with the technology behind everyday life.
