     There have been many great inventions  that changed the way we live.  The first great invention was

one that is still very important today - the wheel. This invention made it easier to carry heavy things and

to travel long distances.

     In the early 1800s the world started to change.  There was little unknown land in the world. People

began to work to make life better.

     In the 19th century, many great inventions were made. Among them were the cameras and the light

bulbs. There were more great inventions  in the early  20th  century,   such as  the  helicopters in 1907,

movies with sound in 1910 and jet planes in the 1930s. This was also a time when a new material was

first made. Nylon came out in 1935. It changed the kind of clothes people wear.

     By this time most people have had a very good life. Man has a desire to explore more.  The world

was known to man but the stars were not. Man began looking for ways to go into space. Russia made

the first step. Since then other countries, including the United States and China,  have made their steps

into space.

     In 1969 man took his biggest step. An American first walked on the moon.  This  is certainly just a

beginning. New inventions will some day allow us to do things we have never dreamed of.
