This topic is broken into units to help in formulating cohesive, effective lessons. Clicking on each unit title below will display appropriate activities, lesson plans, or labs.

Unit materials are a subset of all possible materials available for this topic, selected especially with the new physics teacher in mind. You may instead browse all materials for this topic here.


Conceptual Physics "Static" Electricity Units

Characteristics of "static" electricity include: 1)The number of of positive and negative electric charges within a material may not be equal, 2)voltage is high and current is low, 3) electrical forces (attraction and repulsion) can reach  across great distances, and 4) electric fields (as opposed to magnetic fields) become very important. (Electric fields are also called "electrostatic fields" or "e-fields." Units are not listed in a prescribed order.

Coulomb's methodical measuring laid the foundation for Coulomb's Law, a fundamental principle of electricity and magnetism.  (Open Website)

Many students have difficulty understanding the interactions that cause an electric force between charges. It helps if they begin their investigation with a very simple 1-D representation of the electric force that one particle exerts on another. The user sets the amount of charge so that the particles can either attract or repel; then vector arrows appear to show the amount of force on each particle. One particle can be moved left or right along the line to see the effect of distance on the force. With one click, students can see a graph of the electric force as a function of position.  (Open Website)
