Why bother? • …Moon river, wider than a mile • …Blue moon, You saw me standing alone • …there’s a bad moon on the rise • …Fly me to the moon and let me sing among the stars • …Shine on harvest moon • …if you want to write a song about the moon • …I would fly you to the moon and back • …The moon begins to rise upon my fallen eyes • …I was on the moon when you were born • …till, I'm hanging on the moon • …watched the moon, the blue light of the moon... • …Dancing with the moon, mooning moonstruck

    4. Why bother? A Google search turned up 23,000,000 hits for a search of “moon song lyrics” • …Moon river, wider than a mile • …Blue moon, You saw me standing alone • …there’s a bad moon on the rise • …Fly me to the moon and let me sing among the stars • …Shine on harvest moon • …if you want to write a song about the moon • …I would fly you to the moon and back • …The moon begins to rise upon my fallen eyes • …I was on the moon when you were born • …till, I'm hanging on the moon • …watched the moon, the blue light of the moon... • …Dancing with the moon, mooning moonstruck

    5. Why bother? Don’t even get me started about stars! • …Moon river, wider than a mile • …Blue moon, You saw me standing alone • …there’s a bad moon on the rise • …Fly me to the moon and let me sing among the stars • …Shine on harvest moon • …if you want to write a song about the moon • …I would fly you to the moon and back • …The moon begins to rise upon my fallen eyes • …I was on the moon when you were born • …till, I'm hanging on the moon • …watched the moon, the blue light of the moon... • …Dancing with the moon, mooning moonstruck

    6. Why bother?

    7. Why bother? • The things we see in the sky inspire us • Light and heat come from the Sun • A major impact event will ruin your whole day • The moon (and sun) cause the tides • The orbit of the Earth around the sun causes the seasons • The sun and moon are used for calendars • To see what’s out there.

    8. What’s out there? From near to far, from here to there, funny things are everywhere (TSG 1960) 1) 2) 3) 4) 5) 6) 7)

    9. What’s out there? From near to far: . 1) the Moon 2) Sun 3) Planets 4) Other stuff in the Solar system 5) and other stars 6) Nebulas 7) Galaxies

    10. What’s out there? From near to far: . 1) the Moon 2) Sun 3) Planets 4) Other stuff in the Solar system 5) and other stars 6) Nebulas 7) Galaxies The Universe

    11. Earth-Moon system The moon and the Earth are both about 4.5 billion years old. The moon is made of rock—it may have a partly molten layer inside. It has no standing water or atmosphere Most moon rocks resemble basalt, but some very special types have been found

    12. Earth and Moon Which pair shows their relative sizes?

    13. Earth and Moon Which pair shows their relative sizes?

    14. Earth and Moon Which pair shows their relative sizes? Diameter: Earth 12.7 Mm vs Moon 3.5 Mm Mass: Earth 6000Yg vs Moon 74 Yg

    15. Earth and Moon Which pair shows their relative distance?

    16. Earth and Moon Which pair shows their relative distance? The moon is 400,000 km from the Earth, about 32 times the diameter of the Earth

    17. Earth and Moon Which pair shows their relative distance? The moon is 400,000 km from the Earth, about 32 times the diameter of the Earth

    18. How does the moon affect us? aka: Why bother? Part 2

    19. How does the moon affect us?

    20. How does the moon affect us?

    21. How does the moon affect us? • Tides • Light after sunset (depends on the phase) • Eclipses frighten weak minds. • Basis for some calendars • Inspiration

    22. Tides No moon

    23. Tides With a moon

    24. Tides • The moon’s gravity attracts the Earth and the oceans. • It makes the oceans bulge up on opposite sides of the earth. • The sun does this too, but it’s too far away to do much.

    25. Tides This makes two high tides every day as the Earth rotates. With a moon

    26. Tides • If the sun and moon are lined up, high tides are higher.

    27. Tides • If the sun and moon are lined up, high tides are higher. ……

    28. Tides • If the sun and moon are not lined up, high tides aren’t as high.

    29. Tides • If the sun and moon are not lined up, high tides aren’t as high.

    30. Phases of the moon • The sun illuminates the half of the moon facing the sun. The rest is too dark to see

    31. Phases of the moon • What will you see?

    32. Phases of the moon • What will you see?

    33. Phases of the moon • What will you see?

    34. Phases of the moon • What will you see?

    44. These are called: January 24-30 Jan. 31- Feb. 6 Feb. 7-Feb. 13 Feb. 14-Feb. 20 Feb. 21-27 Full Waning Gibbous Waning Crescent Waxing Crescent Waxing Gibbous

    45. These are called: Full Moon January 24-30 Jan. 31- Feb. 6 Feb. 7-Feb. 13 Feb. 14-Feb. 20 Feb. 21-27 Last quarter Full Waning Gibbous New moon Waning Crescent Waxing Crescent First quarter Waxing Gibbous

    46. Eclipses • The moon can throw a shadow on the Earth at a new moon • The sun is blocked out. • This is a solar eclipse—only parts of the Earth are affected.
