SCIENCE PROJECTS ON THE TELEPHONE
FOR SCHOOL CHILDREN

Are you thinking about a science project on the telephone? First, you should have some basic understanding on how a telephone works. Second, Alexander Graham Bell performed a number of experiments before his famous "Liquid Transmitter" telephone. One such experiment is the "Tuning Fork" experiment which you can perform with several simple components. You can then move on to building your own "Liquid Transmitter" with a few supplies from a Sears store or your local hardware store.
