Machines Introduction Science Project Idea 
During the earliest periods of which we have any record, the earth was receiving just as much energy from the sun as at present. Little use, however, was made of this energy as compared with the present times. As man discovered the use of tools and then machines, civilization advanced. This is now an age of machinery. How man has multiplied his abilities by the use of machines is the project we have for solution.
Before we can understand how machines have enabled man to do much more than he could with his unaided hand, the meaning of several terms which have been used incidentally a number of times must be clearly understood.
