Product Information Physics teacher Ralph Fudge has developed a unique tool to illustrate the simplicity of loudspeakers and how they convert electrical signals into motion and then sound. Ralph has also used the kit to teach electromagnetism, the interaction of magnetic fields, and the mechanical amplification of sound. The kit Includes everything needed for students (working individually or in groups of up to 5) to assemble 5 cup loudspeakers. Also included in each kit are student activities, a student worksheet, background information, and assembly instructions. Recommended for grades 7-12 but can be used to demonstrate principles to younger grades as well. Radio not included. We suggest our radio (45272-01).  Tell a Friend about this item
