All of the simple machines were invented because people wanted to make work easier and to take less time to do the work. People needed to meet their everyday needs for food, shelter, and clothing. They used what was available to them such as trees, rocks, and bones. They also used their bodies. They used these to make simple tools.
The inventing of the lever, screw, inclined plane, the wheel and axle, wedge, and pulley made life easier. After these were created, people were able to do things quicker with less effort. More people were able to do work that they had not been able to before. They were able to get more done in less time than before.
The creation of the simple machines then led to combining them to make more complex machines. This then led to even more inventions that we use today. This is important because simple machines changed our lives and are still changing our lives today. Every day we use simple machines and other machines that are made up of one or more simple machines. We use simple machines to do daily chores and enjoyable things, such as eating.
