Machines are all around us in our daily lives. They help us do a job and can make all kinds of work easier. Machines can also do things for us that we cannot do ourselves. Some machines are very simple. Did you know a pair of scissors is a machine? So is a corkscrew. Other machines, such as spacecraft and planes, are very complicated.The first machines were invented thousands of years ago. Many of these simple machines are still in use today. A lever makes it easier to move loads. A wheel and axle moves things along the ground. A pulley makes lifting easier. These simple machines are part of many complicated machines we use everyday.
