Warm-ups
12/5 - Make a Venn diagram comparing geocentric and heliocentric models. (SS pg. 50)
12/8 - What are Kepler's three laws of planetary motion? (SS pgs. 54, 63-64)
12/9 - In your notebook:
Make an ellipse with thumbtacks, string and a pencil.
Label both focus points, the major axis and the minor axis.
Draw the sun around one of your focus points.
Label the Perihelion and Aphelion. Describe what Kepler's second law says happens at each. (SS pg. 63-64)
