In this unit students take a deeper look into charges beyond the simplified 'opposites attract." Students learn to calculate those attractive and repulsive forces and to show how invisible fields are responsible for them.

This image demonstrates the force of attraction between oppositely charged objects, in this case two pieces of tape. For more information, take a look at repulsive force in action.

In this experiment, young scholars will investigate magnets and how they work. They will understand that two like poles "repel" while opposite poles "attract." They will also observe how a natural force is created by two magnets and...

Contains a procedure for illustrating electrostatic attraction between opposite charges by causing a thin stream of water to bend. The site gives a brief discussion of static electricity, as well.

Students describe and create an experiment to prove that like poles of magnets repel each other while opposite poles attract. Using the experiment, they use the data to support the claim that the repelling force is stronger than the...

This lesson focuses on electric charges. Electric current is the flow of electric charge. Some insulating materials become electrically charged when they are rubbed together. A substance that gains electrons becomes negatively charged,...

A simple activity that investigates the basic principles behind static electricity. The activity is in lesson plan format that meets NSES standards.

Peter the Great. This prince is one of the most extraordinary figures in history. As a boy he showed a great eagerness for knowledge in departments which were not generally attractive to the members of royal families. He cared nothing...
