2 Phases, Eclipses, and Tides L.O. SWBAT describe the phases of the moon and tides.

3 © A. Weinberg When you look up in our night sky, you will see the moon! Phases of the moon Different shapes of the moon as seen from Earth. Caused by the motion of the moon around Earth.

4 © A. Weinberg Earth’s Moon Review 1 Moon (planetary satellite) Orbit is oval shaped Moon’s “day” and “year” are the same length. The “near side” always faces Earth The “far side” always faces away form the Earth

8 © A. Weinberg Earth’s Moon -Review 29 ½ days to revolve around the Earth Does not produce light, it reflects the sun’s light Solar eclipse: Sun – Moon – Earth Lunar eclipse: Sun – Earth - Moon

10 © A. Weinberg Lunar Eclipses

11 © A. Weinberg As the moon revolves)ar ound the Earth, it looks like it has different shapes. The shape of the moon does not really change. It just changes its location in space.

12 © A. Weinberg Let ’ s take a closer look at the phases of the moon. During a new moon, the moon looks dark.

13 © A. Weinberg As the surface of the moon that we see gets bigger, we say that the moon is waxing. This is a waxing crescent.

14 © A. Weinberg When the moon is ¼ of the way around the earth, it is in its first quarter phase. We see it as half lit. This is a waxing quarter moon.

15 © A. Weinberg After the quarter moon, the moon is moving towards a full moon. We call this a waxing gibbous moon. Notice that the bright part of the moon is getting larger. That’s what we mean by “waxing.”

16 © A. Weinberg Now it ’ s time for a full moon. The entire face of the moon that we are able to see shines during the full moon.

17 © A. Weinberg Following the full moon, the surface of the moon seems to be getting smaller. We call this a waning moon. This is a waning gibbous moon.

18 © A. Weinberg Now that the moon is ¾ of the way around the Earth, it seems to be half lit. We call this a waning quarter moon.

19 © A. Weinberg Before we get to the new moon, we see a sliver of moon shining up in the sky. This is a waning crescent.

20 © A. Weinberg Now we see a new moon again. It takes the moon about 1 month (29 ½ days) to go through the phases

21 © A. Weinberg The Gravity of the Moon pulls on the oceans and causes the tides.

22 Tides Tides: the rise and fall of water. every 12.5 hours or so The force of gravity pulls the moon and Earth toward each other. As Earth rotates, the moon's gravity pulls water toward the point on Earth's surface closest to the moon.

23 © A. Weinberg THE MOON ILLUSION ASAPScience DNews Does the Moon Really Control the Tides?

24 © A. Weinberg Summary (3-4 Sentences) 1.Today I learned... 2.Describe the movement of the moon. 3.What causes the Earth’s tides?
