Force, Motion, Energy

5.6A: Explore the uses of energy, including mechanical, light, thermal, electrical, and sound energy.

5.6B: Demonstrate that the flow of electricity in closed circuits can produce light, heat, or sound.

5.6C: Demonstrate that light travels in a straight line until it strikes an object and is reflected or travels through one medium to another and is refracted.

5.6D: Design a simple experimental investigation that tests the effect of force on an object.
