1. Satellites and The Moon Astronomy Page 7

2. SWBAT: Identify what causes the phases of the moon. Draw and interpret each moon phase.

3. Do Now: Describe where the moon gets its light from.

4. Satellite: a celestial body orbiting the earth or another planet • Earth is a satellite of the • Sun • The moon is a satellite of the • Earth • Why do the distance between the sun and earth change? • Shape of the orbit not a perfect circle • Gravitational pull changes due to distance

5. Why so many? Craters What are these? No atmosphere Why is Earth not like this? weathering, erosion, atmosphere

6. Phases of the Moon

7. What causes the phases of the moon? The moon's revolution around Earth.

8. The apparent shape of the moon depends on the changing positions of the • Earth, moon, and Sun

9. How long does it take for the moon to revolve around Earth ? 27.3 days One complete orbit of the moon around The Earth takes? ESRTs p15

10. One complete cycle the moon’s phases takes • 29.5 days • Explain why there is a 2.5 day difference • Because you need to go back to the first phase that takes another 2.5 days

11. How long does it take for the moon to revolve around Earth ? 27.3 days One complete orbit of the moon around The Earth takes? ESRTs p15

12. What phenomenon does this explain? We only ever see one side of the moon.

13. Why does the moon rise later each day? because as the Earth rotates, the moon revolves

14. EXIT: • Complete questions 3 and 4 on your note packet page 9. Be prepared to discuss.

16. SWBAT: Identify what causes the phases of the moon. Draw and interpret each moon phase.

17. Do Now: At your table draw and describe the difference of what you see during a lunar and solar eclipse. Be prepared to share with the class.

19. What phase of the moon is this? New Gibbous New Crescent 3rd Quarter

20. How many hours is the moon visible each day? 12 hours

21. What is "waxing"? more of the moon's surface can be seen

22. What is "waning"? less of the moon's surface can be seen

23. The phases of the moon are what type of event? Cyclic

24. Going to the Moon
