National Standards for Grades 7-10

Students explore wavelength, frequency and amplitude while immersed in hands-on experimentation. As students build their own old fashioned Crystal Radios, they explore the effects of coil design, building materials, and antennae number and length, on maximizing tuning and signal strength. Then students upgrade their crystal radio into a transistor radio. Ideal for hands on learners, as intuition plays a role in developing antenna design solutions, iterative testing, and making modifications for improvements. Great for introducing guided inquiry-based learning. 

This kit contains a complete instructor’s manual with reproducible stepwise student protocols. Allow three 45-minute lab periods for building.
