The above photo series is from a recent 5th grade student's Crystal Radio science project. The student used the https://store.sciencebuddies.org/Elec_p014/COM-0001-KIT/Crystal-Radio-Kit.aspx?from=Blog">Science Buddies Kit for his science experiment but modified the experimental design of the crystal set during construction. After building the set, the student put the radio to the test, testing one of the many variables available for exploration with a crystal radio. The result? The student was one of the top five participants at his middle school science fair. Congratulations!
