Wind Energy and Turbines.
๐ฏ Your mission
Run the sim. Spot the pattern.
โก The twist
The opposite of what you expect is often what happens.
Mind = Blown
๐ฅ A bolt of lightning is 5 times hotter than the surface of the sun.

Steps
Look at the vocabulary words and write a definition for each in your own words.
Build an electromagnet by wrapping insulated wire around a nail and connecting it to a battery. Test how many paper clips it can pick up. Try adding more wire coils.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?
