Product Details

Students safely discover the essential components of an electric circuit as they build their very own audio conductivity testers. Once the testers are assembled, students use the inquiry method to determine the conductivity of common solids and liquids. The audible sound emitted when the circuit is complete gives immediate and unmistakable results. Students also explore relative resistance as the volume and pitch of the buzzer varies with conductivity. At the end of the lab, testers may be disassembled, ready to be built again by the next class. Kit includes complete instructions with reproducible student handouts, valuable Teacher Notes with suggestions for common conductors and insulators for testing, and enough reusable materials to make eight conductivity testers. A 9-V battery is required for each tester, but not included.
