Energy Unit NGSS KCAS 7th Grade Science
Radiation • Symbol for waves • Heat WITHOUT touching • Examples • Sun heating pool • Laying out/Tanning • Placing hand over stove burner
CONDUCTION • Heat moves to cooler object • Heat WITH touching • Examples • Touching/Sitting on Car Leather that has been in Sun
Convection • Lava lamp demonstration • Examples • Wind/Air currents • Heating & Cooling Rooms • Convection Oven
Nuclear energy • Atom MUST SPLIT to release energy
Mechanical energy • Must have MOVING parts or gears • Examples • Animals • Humans
Electromagnetic (light) Energy • Anything that has light
Electrical energy • Wires? Or Plugs in? HAS ELECTRICAL ENERGY
Chemical energy • Considered P. E. until used
Thermal energy • HEAT energy • Anything that holds or releases heat • Measured by TEMPERATURE • More Volume = More Energy
Law of conservation of energy • Begins & ends with the same amount of energy • May end up being a different type of energy
Potential energy • On Ground = 0 P. E. • Drawing
Kinetic energy • An object IN MOTION • Examples of more K. E. • Mass – Center/Lineman • Speed – Forward/Running Back
When a ball is dropped • Drawing • Result P. E. changes to K. E.
