You’ll be shocked by how well this simple, do-it-yourself electroscope works! Large, aluminum-covered foam ball stores static-electric charge better than most commercial electroscopes. A variety of simple electrostatic demonstrations can be performed showing students how the parts of the electroscope work. Use the PVC rod, test tube and wool fabric provided to produce negatively and positively charged rods to charge the electroscope. Next, use the charged electroscope to test the polarity of different objects’ static-electric charge. Includes enough materials to build one electroscope. Teacher Demonstration Instructions and background information are provided.
Concepts: Static electricity, electron affinity, charge distribution, induction, conduction.
Time Required: 20 minutes
Note: Needle-nose pliers with wire cutters are required and available separately.
