14. STANDARD IV : Students will understand the relationships among energy, force and motion. Objective 1: Investigate the movement of energy through various materials.

15. Relate the energy of a wave to wavelength The shorter the wavelength the greater the energy. The top wave has the shorter wavelength and thus has more energy than the bottom wave.

16. Compare the movement of energy (i.e., sound, light, earthquake waves, heat) through various mediums. A medium is what the waves travel through: Solids Liquids Gases http://www.youtube.com/watch?v=2Wlh3M2a10U

17. Describe the spread of energy away from an energy-producing source. Energy spreads away from the source in all directions like a rock thrown in a pool of water.

18. Compare the movement of heat by conduction, convection, and radiation and provide examples of each http://www.youtube.com/watch?v=7MVEePXwAeI

19. Demonstrate how white light can be separated into the visible color spectrum. http://www.youtube.com/watch?v=yvMnURU1T24

20. Examine the force exerted on objects by gravity Distinguish between mass and weight. http://www.youtube.com/watch?v=1whMAIGNq7E

21. Cite examples of how Earth's gravitational force on an object depends upon the mass of the object. The bigger the mass, the bigger the force of gravity.

22. Describe how Earth's gravitational force on an object depends upon the distance of the object from the Earth. As an object leaves the surface of the Earth, the pull of gravity on the object becomes less.
