The Telephone

The Telephone

Alexander Bell built a telephone in 1876. He had to learn a lot of science to do it.

Here are some telephones from long ago. Do these early phones look like your phone? Phones use electricity to send calls. Some calls are sent through wires. Some calls are sent through the air.

Using the phone is a great way to talk to friends and family. Who do you like to talk to on the phone?

Using a phone is a big help if there is trouble or danger. For example, if you saw someone get hurt, you or a grown-up would dial 9-1-1.

The people who answer the phone at 9-1-1 will send help. Use your head. Tell them what the problem is. Do not hang up because they need to find out where you are.
