1. Outline Nicolai Copernicus' biography.2. What is the Heliocentric System Model? Draw and label a diagram of this systems.
3. Draw a sequence of four frames that diagram retrograde motion in the Copernican System. Briefly explain what an observer would see from Earth when viewing retrograde motion.
4. List the three assumptions that held back astronomy from the time of Aristotle (350 B.C.) until the 1600's.
5. Which of the assumptions (listed above in #3) did Copernicus change?
6. Explain why Copernicus is not really considered a revolutionary.
7. Who is Aristarchus of Samos? When did he live and what does he have to do with Copernicus?
8. a) Describe the Parallex Effect.
b) Give an example where parallax was a factor in someone's or your observations.
c) Explain how parallex effect can alter your ability to make inferences.
