INTRODUCTION

Electrical Safety World uses articles, experiments, and activities to explain electricity-related science concepts, and how to use electricity safely in daily life. The content addresses many state and national science and health education standards for grades 4-6.

This presentation guide provides the objective for each page spread, ideas for classroom discussion, activity and puzzle answers, and suggestions for experiment setup and completion.

Pages 2 & 3: Introduction to Energy Use and Vocabulary

Objective: To make students aware of how they use energy (i.e., for light, heat, etc.) and the sources of energy they use. To familiarize students with some new concepts and vocabulary.

Energy Use Chart: Help students complete the energy use chart. Ask them to consider whether they did any of the following things today: took a bath or shower, cooked food, watched a TV show or video, listened to music, were driven to school, enjoyed a warm (or cool) home, or played a computer game. Ask students what appliance or equipment they used to do each thing. Have them record their answers in the first and second columns. If students are not aware of the energy sources that run the appliances and equipment they used, ask them to check with their families and fill out the third column at home. (Tips for recognizing energy sources: Electrical appliances plug into a wall outlet and portable electric devices run on batteries. Appliances and equipment that use natural gas or other fuels have a flame inside when they are on.)

What Do You Think? Students’ answers will vary. Depending on your climate and season, keeping warm or cool without using energy may require a lot of ingenuity. Students may find it interesting to speculate about—or do some research on—how people native to your area kept warm or cool before the invention of modern heating and air conditioning systems.

Word Search Key: The first letter of each word is underlined and italicized.
