This collection looks at inventors and inventions that changed our lives: the telegraph, photophone, animation, sewing machine, ice cream cone, nuclear fission, flight, and others. It includes Thomas Edison's journals and failed inventions, and Alexander Graham Bell's notebook entry describing the first successful experiment with the telephone (March 10, 1876). George Westinghouse, James Smithson, Benjamin Banneker, and Samuel Morse are among others profiled. (less)

Sound Curricular Unit

Sound Curricular Unit

Students learn the connections between the science of sound waves and engineering ... (more)

Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel through different mediums, and are enhanced or mitigated in designed sound environments. Students are introduced to audio engineers who use their expert scientific knowledge to manipulate sound for the production of music and film. They learn how the invention of the telephone pioneered communications engineering, leading to today's long-range communication industry and its worldwide impact. Students analyze materials for their sound properties used in acoustic design, learning about the varied environments created by acoustical engineers. Hands-on activities include modeling the placement of microphones to create a specific musical image, modeling and analyzing a string telephone, and using what they've learned about sound waves and materials to model a room to serve as a controlled sound environment.

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. (less)

In this activity, students investigate how sound travels through both 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 scenario to redesign the string telephone for distance. They think about their model as it compares a modern telephone and the impact the telephone has had on society. (less)
