Study Points• What is a mare?
• What causes craters, especially on the Moon?
• What is the Moon’s terminator?
• Explain why the Moon exhibits phases. Draw the Sun-Earth-Moon system showing the Moon’s orbit (not to scale), draw Moon in 8 different positions in its orbit and shade in Earth and Moon indicating which side is lit and which is dark. Use that drawing to explain what phase you will see for each of the Moon’s locations you drew.
• Knowing when New Moon occurs, predict about when First Quarter, Full, and Last Quarter Moons will occur. Know about how many days are in between the phases.
• Explain why the Sun, Moon and stars appear to rise in the east and set in the west. Explain why we have day and night using a sketch of Sun-Earth-Moon system to help.
• In one hour, the Moon, Sun, and stars move about how many degrees in the sky? (hint: how many degrees does the Earth rotate in 24 hours)?
• In one day, the Moon moves about how many degrees in the sky? (hint: about how many degrees does the Moon revolve in 30 days)?
• What direction does the Moon move from one night to the next? Explain?
• Explain why you always see the same face of the Moon.

Moon Phases Observation• 10 points
• From Jan. 23 to Mar. 5 to complete
• Record phases and location of the Moon over 4 separate dates. Observe 4 different phases of the Moon. There are 8 phases of the Moon over ~28 days.
• Class website has more details in Moon Phases observation file.
– Helpful website: https://www.timeanddate.com/moon/usa/minneapolis
• Turn in the Moon Phases Observation sheet or submit on D2L or take a picture of it and email it to Raquel.
