Unit 3: The Sun as a Star

Learning Goals:
i. Identify how long the sun's magnetic cycle lasts and ways in which the sun affects Earth. ii. Identify layers of the sun, their temperature, and what makes the different. iii. Identify what powers the sun, explain how it works, what is created, and relate it to Einstein's equation. iv. Be able to explain how Earth's magnetic field is created, why Mars doesn't have one, and how this protects us from the sun. v. Explain how we know what the sun is made of.
