  1. Energy Unit NGSS KCAS 7th Grade Science

  2. Radiation • Symbol for waves • Heat WITHOUT touching • Examples • Sun heating pool • Laying out/Tanning • Placing hand over stove burner

  3. CONDUCTION • Heat moves to cooler object • Heat WITH touching • Examples • Touching/Sitting on Car Leather that has been in Sun

  4. Convection • Lava lamp demonstration • Examples • Wind/Air currents • Heating & Cooling Rooms • Convection Oven

  5. Nuclear energy • Atom MUST SPLIT to release energy

  6. Sound energy

  7. Mechanical energy • Must have MOVING parts or gears • Examples • Animals • Humans

  8. Electromagnetic (light) Energy • Anything that has light

  9. Electrical energy • Wires? Or Plugs in? HAS ELECTRICAL ENERGY

  10. Chemical energy • Considered P. E. until used

  11. Thermal energy • HEAT energy • Anything that holds or releases heat • Measured by TEMPERATURE • More Volume = More Energy

  12. Law of conservation of energy • Begins & ends with the same amount of energy • May end up being a different type of energy

  13. Potential energy • On Ground = 0 P. E. • Drawing

  14. Kinetic energy • An object IN MOTION • Examples of more K. E. • Mass – Center/Lineman • Speed – Forward/Running Back

  15. When a ball is dropped • Drawing • Result  P. E. changes to K. E.
