Study Static Electricity with Electroscopes—Investigate Induction

Supporting document included
This is an additional download that supports the video.
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.

Answer Keys and Teacher Notes are there to address most questions and issues that might arise in this study—you shouldn’t have to do outside research unless you want to. 

Concepts Addressed
• 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.

Materials Needed
DIY electroscope (glass jar, paperclips, holepunch, scissors, index card, charging rod and cloth)

Answer Key
Extensive teacher notes address the many questions that come up. You shouldn’t have to do outside research on this topic unless you want to.
