Exploratorium: Science Snacks: Charge and Carry
This site from The Exploratorium Museum is a full description of a short activity. An electrophorus plate and a Leyden jar are made. The electrophorus is charged by induction. Its charge is transferred to the Leyden jar by conduction...
Concord Consortium
Concord Consortium: Spring and Mass Model
An interactive tool where students can explore how a spring behaves, and how changing the elasticity, mass, push/pull force, and friction affect its motion or period. As the spring moves, its motion is shown on a distance-time graph.
