Although scientists do not fully understand the mechanism behind lightning, they think it is created when particles collide with other particles, causing them to generate and build up large amounts of static charges. The same basic process that creates lightning also occurs on a much smaller scale when you get a shock after shuffling across a carpet and touching a doorknob. What is giving you a shock is static electricity. In this set of activities, students will generate static electricity by rubbing or “charging” a balloon.
Science Friday is looking to work with educators like you to create stellar STEM activities. Applications for the 2019 program are open!
