What’s the connection between the static electricity shocks we experience touching doorknobs and a full-blown lightning storm? In this overview, viewers learn the key scientific principles related to electricity, starting at the atomic level where protons and electrons with positive and negative charges attract and repel one another, leading to various types of electrical discharge (demonstrated using simple objects such as balloons or freshly dried laundry). Building upon the basic concepts, the program then offers a rudimentary explanation of what causes lightning and thunder. In addition to a teacher’s guide and accompanying curriculum, the DVD also includes extras such as labeled slides, a glossary, and an iMovie project. Nicely illustrating key terms and concepts, this solid introduction to electricity aimed at young audiences is recommended.
