Build a crystal radio to experiment with wavelength and frequency!

What happens when you change a radio’s coil design or building materials? How does antenna length affect how a radio receives frequencies? These are the types of questions students will answer through hands-on projects. Students design and test their radios, making adjustments along the way to improve reception. After developing a simplistic crystal radio, they learn how to transform it into a transistor radio. Teacher’s manual includes building suggestions and ideas, as well as reproducible student worksheets. Class Kit is best for up 24 students and features enough material for 6 radios. Build one radio using the Activity Kit, ideal for small group learning. Complete content lists available in kit manuals. Recommended for Middle School and up.
