Static Electricity STSE Jigsaw SNC1D1 – submitted by Michael Balzer

This lesson is used for students to analyse the design of a technological device that protects other devices by using or controlling static electricity (such as paint sprayers, photocopiers, lightning rods or grounding wires).  I use this lesson near the beginning of the electricity unit in SNC1D1, after introducing static electricity and charging by friction, contact and induction.

Using a Van de Graaff generator – YouTube

From the Institute of Physics and the National STEM Learning Centre and Network (https://www.stem.org.uk/), this video is aimed at teachers and shows how to get the best out of a Van de Graaff generator. In the video, Michael de Podesta explains how the generator works and gives some tips on getting consistently good results when using the apparatus. The video concludes with a simple but effective demonstration of charge.
