Heat, Light, and Sound

Students in sixth grade will study sources of energy as they study the source of heat, light, and sound. After study of sources, students will be able to compare and contrast how heat, light, and sound are produced. In their study of energy, they will need to explore the significance that these three forms of energy have for present and historic cultures. Students should also explore living sources of heat, light, and sound that exist in plants and animals.

Characteristics of light and sound will provide data for students to set up experiments. Students can draw some inferences about light reflection, light refraction, and the separation of light into various colors through experiments. Students will be able to experiment with the ability of variety of materials to absorb sound. In studying sound, students need to be aware of the tremendous power of communication we have through sound. Discussions involving the issues related to sound will help students develop their evaluative skills as they learn to take a stand on an issue.
