1. What occurs during fusion? Agenda for Wednesday Feb 16 th 1.Movie 2.Alternative sources of energy **Bring books tomorrow!!

2. Draw a picture of fission and fusion. Agenda for Thursday Feb 17 th 1.Finish Movie 2.Energy sources 3.Electricity

3. Renewable vs. Nonrenewable Nonrenewable consumed faster than it is formed Renewable can be replaced at the same rate at which it is consumed

4. What is meant by clean energy? Energy that does not pollute the atmosphere when used – Electricity, nuclear power, wind, water Compare to coal and oil, that do pollute

5. How do we generate power from wind, sun, water, etc? Water flowing through a dam turns a turbine, which turns a generator As the turbine blades turn, so do a series of magnets inside the generator Giant magnets rotate past copper coils, producing alternating current (AC) by moving electrons

6. How do we generate power from wind, sun, water, etc?

7. Generators and motors transfer mechanical energy and electric energy from water, wind, sun Uses rotational/potential energy to rotate turbine which generates electricity using electromagnetism

8. Energy Sources Fossils Fuels Oil, coal, natural gas Nonrenewable Sun is the source of energy Plants convert sun’s energy into chemical energy Plants die, get buried, under heat and pressure turn into fossil fuels

9. Energy Sources Solar Power plants and solar cells trap sun Convert into electricity Wind Comes from sun – heats earth differently which causes wind

10. Energy Resources Water Water cycle Dams built on fast moving rivers Geothermal Steam/hot water inside earth Rises and turns turbines = electricity Atoms/Fusion/Radioactivity
