Electroscopes are a simple instrument that kids can use to give evidence for static charges. Kids can build their own... once built they can last for years. They have both a qualitative and a quantitive aspect. Electroscopes are a great way to begin to understand induction which is one of the more challenging concepts involved with electrostatics.
• The closer a charged item is to an object, the greater the force it exerts.
• Static charges can cause objects to move.
• Items can be charged at a distance.
