Think About It
This morning, did you wake up and brush your teeth in the dark? Many of you may wake up when your parents turn on the light in your bedroom.
Turning on the light is as easy as flipping a switch. Many of us do not even realize how valuable light is until we no longer have it!
Have you ever been at school or at home when the power went out and you had no electricity? What did your parents or teachers do to make sure you could see?
A long time ago, people did not have electricity. They had to use other methods to see. Most often, while working on schoolwork or writing a letter, a gas lantern or candle was needed to see what you were doing. This could be dangerous if you accidentally left the candle burning too long or if it tipped over. Today we are going to learn about a man named Thomas Edison. He improved the light bulb so that we can easily have light in our homes and schools today.
