More About Lights
Long ago, people used fire for light. They would make a fire to see at night. Then, they made lamps with oil. Now, we have electric lights that are bright and safe.
In our lives, we use lights every day. We turn on lights in our homes, schools, and cars. Lights help us read, play, and do our work. Without light, it would be hard to see.
In the future, lights will get even better. We might have lights that change colors by themselves. There are also lights that save energy and help the Earth!
