Alexander Graham Bell was interested in sound because his mother and wife were deaf. He became a teacher for deaf students in Boston. He invented the telephone in 1876, with the help of his assistant Thomas Watson. The first words he said on the telephone were, “Mr Watson, come here. I want to see you.”

A Dutch eyeglass maker called Lippershey invented the first telescope. But Galileo used the telescope to look at the sky first. He saw the mountains and craters on the moon, as well as the Milky Way. He also discovered the sun had sunspots and Jupiter had moons.

The Chinese Han Dynasty invented the compass to find directions first, but the Song Dynasty developed it during the 11th century. People started to use it in Europe in the 13th century.

Many centuries ago people in Egypt made a kind of paper from the papyrus plant. This is where the word paper comes from. The people of Greece and Rome learned to do this too.  The Romans wrote on animal skin or wood. But the paper we know was first invented in ancient China. They used different plants to make paper.  The oldest existing paper with writing on it was found in a watchtower in the Great Wall of China.
