4. Phases of the moon As the Moon revolves around the Earth, the moon appears to change shape in the sky. The moon does not actually change shape, but shadows are created giving the moon phases.

5. Phases of the moon Full Moon Quarter Moon

6. Crescent Moon Almost New Moon

7. Making the phases of the moon The moon revolves around the Earth every 27 1/3 days. The Moon is inclined above and below the plane of the Earth and sun by 5 degrees

8. Making the phases of the moon As the Moon revolves around the Earth, the phases are created by the angle that the Earth views the light from the sun being reflected off the moon.

9. 8 Phases There are 8 phases: 1.New Moon 2.Waxing Crescent 3.Waxing Quarter 4.Waxing Gibbous 5.Full Moon 6.Waning Gibbous 7.Waning Quarter 8.Waning Crescent

10. Waxing vs. Waning Waxing means getting bigger, waning means getting smaller

12. Eclipses Two kinds of eclipses 1.Lunar Eclipse 2.Solar Eclipse

13. Lunar Eclipse A lunar eclipse is when the Moon is in the Earth’s shadow.

14. Solar Eclipse A Solar Eclipse is when the Earth is in the moon’s shadow. More rare than lunar eclipse. Seen on earth once every 200 years on average.

21. Moon Facts continued Rotation is the spinning of an object on its axis. Revolution is the orbit of an object around another object. Eclipses do not occur every month because of the incline of earth’s revolution.

22. Moon exploration First spacecraft to explore the moon happened in 1959. It was part of the Luna series launched by the former USSR The US also created the Pioneer series which were competing with the Luna series to get to the moon.
