In this lesson, students are introduced to communications engineers as people who enable long-range communication. In the lesson demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon using a slinky. Finally, Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering.

Students investigate how sound travels through string and air. First, they analyze the sound waves with a paper cup attached to a string. Then, they combine the string and cup with a partner to model a string telephone. Finally, they are given a design challenge to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the invention of the telephone has had on society.
