Part of Unit: Force, Work, Rate, Power, Energy, and Resistance
Lesson Plan Overview / Details
In this lesson students will build a speaker coil. When they hold the coil in their teeth and plug it into a sound source, they will hear the music in their head through bone conduction. Students will then draw a diagram of a speaker with an explaination to demonstrate their new found knowledge.
