Teacher Notes:
Explain how electricity (and magnetism) interact with matter.
All students should know safety precautions about electricity. Beginning in the third and fourth grade, students
should be constructing simple and useful electrical circuits. They should be able to understand how a flashlight
works. In the middle school, the building of simple circuits is explained in terms of flow of current. Students
also move beyond looking at battery powered toys to explaining how electrical devices such as radios and
stereo systems work using appropriate safety precautions. Finally, at the high school level students will explain
how current is controlled in simple, series and parallel circuits. They also will consider the interaction of wires
and magnets to produce electric currents.
