We look at examples of static electricity; the meaning of static electricity; revisiting magnetism; electromagnetic forces behind static electricity using the example of rubbing hair with a balloon; we observe how hair is attracted to the balloon. We explain the effects of friction and how negative electrical charges migrate to the balloon leaving the girl’s hair with excess of positive charges.
How amber is fossilized tree resin; how the ancient Greek philosopher Thalus of Miletes was the first recorded person to observe static electricity in action in 600BC; how he used amber in an ancient static electricity experiment; the meaning of the ‘triboelectric’ series; what the triboelectric series tells us; which materials have a tendency to become positively or negatively charged.
In this science article we look at two different simulations which enhance students’ understanding of static electricity; one of the simulations explains how and why balloons stick to a wall and the other one explains how and why after walking across acarpet and touching a metal door handle you can get an electric shock; links to other websites with other static electricity experiments are suggested.
Examples of static electricity; the science behind static electricity ; simplified look at the structure of atoms including negatively charged electrons and positively charged protons ; the special role that electrons fulfilll in generating static electricity; positive and negative electrical charges; generating static electricity using a balloon; a van de Graaff generator; suggestions science experiments.
