(5.6) Force, Motion and Energy

(5.6) Force, Motion and Energy

Overview

Students explore uses of energy, including mechanical, light, thermal, electrical, and sound energy, in every day life. They experiment with electrical circuits, and observe how electric current can produce light, heat or sound. Students also conduct detailed investigations about light, and discover that light travels in straight lines, and can be reflected and refracted. Building upon their explorations of force and motion in fourth grade, fifth grade students design an experiment that tests the effect of force on an object.
