1 Plan For Today Finish up from last time: expanding universe Earth s orbits: solstice, equinox, seasons Begin Phases of the moon if time permits Homework 2 due on Tuesday

2 How Big is Big? On a 1:10,000,000,000 scale, what is the approximate size of: The sun? The earth and other planets? The distance from the sun to earth? The distance from the sun to neptune? The distance of one light year? The distance of one Astronomical unit (AU)? 2

3 So, why are things so far, if gravity pulls things together? 3

4 Scales of Time Starts with the Big Bang Edwin Hubble discovered that: 1. Practically every galaxy outside of local group is moving away from us 2. The further away the galaxy is, the faster it moves away. Why is this? 4

5 Scales of Time Starts with Raisin Cake Analogy the Big Bang 5

6 SEASONS! Why are there different seasons?

7 Earth rotates and orbits at the same time Image taken from earthgauge

8 At Winter Solstice, no direct sun at North Pole. Shortest day of year in Northern Hemisphere

9 At Summer Solstice, direct sun all day long at North Pole. Longest day of the year in Northern Hemisphere

10 Equinox sun rises and sets directly East/West. Day and night = 12 hours

11 Activity on Seasons

12 Phases of the Moon Plan For Today Homework: Homework 2

13 Review Questions

14 What causes the seasons? a. In summer the earth is closer to the sun (because the orbits in an elliptical pattern). b. In summer the tilt of the earth s axis makes the part of the earth we are on closer to the sun. c. In summer the sun is up for more hours. d. In summer the sun climbs higher in the sky so its rays hit the ground more directly. e. Both c and d

15 If the tilt of the earth s axis to its orbital plane was 40 degrees instead of 23 ½ degrees but its distance to the sun remained the same, what would happen to the seasons? a. They wouldn t change much. b. They would become less extreme winter and summer would be more alike. c. They would become more extreme winter would be colder and summer would be hotter. d. The whole earth would get colder. e. The whole earth would get warmer.

16 The Phases of the Moon - Vocab

17 The Phases of the Moon - Vocab New Moon Waxing Gibbous 1 st Quarter Waning Crescent Full Moon 3 rd Quarter

18 WAXING Wax On, Wane off WANING

19 Phases of the Moon DEMO

20 Phases of the Moon DEMO (with orange) Computer Demo: aw_bennett_cosmic_4/tcp4ma/ Tutorials/flash/MoonPhases/ MoonPhases.html

21 Which Moon position (A-E) best corresponds with the Moon phase shown?

22 Sketch how the Moon would appear at each of the other four positions.

23 Shade the illuminated portion of the Moon at each location

24 Which Moon position (A-D) best corresponds with the Moon phase shown?

25 How much of the entire Moon s surface is illuminated by the Sun during this phase? a. None of the surface is illuminated. b. Less than half of the surface is illuminated. c. Half of the surface is illuminated. d. More than half of the surface is illuminated. e. All of the surface is illuminated.

26 How much of the Moon s illuminated surface is visible from Earth for this phase of the Moon? a. None of the surface (visible from Earth) is illuminated. b. Less than half of the surface (visible from Earth) is illuminated. c. Half of the surface (visible from Earth) is illuminated. d. More than half of the surface (visible from Earth) is illuminated. e. All of the surface (visible from Earth) is illuminated

27 Would your answers to the last two questions change if the Moon were in the third quarter phase rather than the new moon phase? Explain.

28 Student 1: The phase of the Moon depends on how the Moon, Sun, and Earth are aligned with one another. During some alignments only a small portion of the Moon s surface will receive light from the Sun, in which case we would see a crescent Moon. Student 2: I disagree. The Moon would always get the same amount of sunlight; it s just that in some alignments Earth casts a larger shadow on the Moon. That s why the Moon isn t always a full Moon. Do you agree or disagree with either or both students? Discuss with the person sitting next to you.

29 Predicting Moon Phases

39 If the Moon is a new Moon when it rises, which Moon will it be when it sets? a. Full moon b. 1 st quarter moon c. New Moon d. 3 rd quarter moon e. Waxing Gibbous

40 Think through the next page of questions and answer them on your own. Phase? What time is Moon high in sky? What time will Moon rise? What time will Moon set?

41 At what time would you look to see a first-quarter Moon at its highest position in the sky? a. 6 AM b. Noon c. 6 PM d. Midnight

42 If the Sun set below your western horizon about 2 hours ago, and the Moon is barely visible on the eastern horizon, what phase would the Moon be in at this time and location?

43 Think through the remaining question and answer it on your own. Sliver of Moon is visible in early morning. What phase is it and where is it in the sky?

44 Wrap up Questions

45 You observe a full moon rising in the east. Which image shown below best represents how the Moon will appear when it sets?

47 Which phase of the Moon rises in the east as the Sun rises in the east? a. First quarter b. Gibbous c. Full d. Third quarter e. New

48 During the full moon phase, how much of the Moon s surface is being illuminated by sunlight?
