Warm-ups
11/14 - Make a Venn diagram comparing geocentric and heliocentric models. (IS pg. 467-469)
11/15 - Write the full names and summarize the actions of the 4 people most responsible for giving us the Heliocentric model of the universe. (IS pgs. 468-469)
11/16 - Describe how the force of Gravity is a Centripetal Force. (IS pg. 194-195)
Use the following simulation for the My Solar System Worksheet:
11/20 - In your notebook: (IS page 509)
Make an ellipse with two thumbtacks, string, and a pencil.
Label both focus points, the major axis and the minor axis.
Draw the sun at one of the focus points.
Label the Perihelion and Aphelion.
Describe what Kepler's second law says happens at Perihelion and Aphelion.
11/21 - What does NASA stand for? Why was it formed? (Old ES pg. 599)
11/22 - Why does the moon have so many impact craters, while the Earth only has a few that we can see?
11/27 - NASA considered 3 modes to get to the moon: Direct Ascent, EOR, and LOR. Make a list of Pros and Cons for each.
What trade-offs led them to finally select LOR to get to the moon?
11/28 - How does a rocket work according to Newton's Third Law of Motion? (Old ES pgs. 598-600)
11/29
Make a hypothesis for how the moon became the moon.
What evidence could support your hypothesis?
What test or evidence could prove your hypothesis wrong?
11/30 to 12/1 - Use the following simulation for Newton's Laws and the Lunar Lander WS :
Direct Ascent uses a super large rocket to send a large space ship to the moon that lands backwards and then comes back to earth.
Earth Orbit Rendezvous (EOR) uses 2 small rockets to take fuel and a large spaceship into Earth orbit where it is brought together and then proceeds to the moon. 5:45
Lunar Orbit Rendezvous (LOR) uses 1 large rocket to take a Command Unit and small specialized lander to orbit the moon.
