Watch: Watch the video below, look for the big idea:
You need some alternative source of energy to transform into electricity.
Note: People often say we "generate electricity," but according to The Law Of Conservation of Energy, energy can't be neither created nor destroyed.

What questions came up for you as you watched the video?
Play with the simulation for a few minutes (linked here if you want to open in a new tab and have it be larger).

Question 7

Besides dragging the magnet around, the simulation allows you to spin or flip the magnet. Compare the electricity generated by dragging the magnet through the coil and just flipping while the magnet is within the coil?

Question 8
8.
Now that you have played with the simulation, select all the materials that you would need to generate electrical energy:
In reality, it's easier to spin something in a circle (think wind turbine or water wheel) than to push it back and forth, so electric generators actually spin the coils inside of the magnet - but the result are the same.

Summarize: How does a generator work? Use the following words: movement, magnet, coil of wires.
