Static Charge
Static charge (electrons, in this case) can be physically transferred from one object to another through friction. Students will use rubber, glass, fur and silk to create positive and negative charges, and investigate how these charges cause forces. An electroscope will be used to demonstrate charging by conduction and induction.
