1. Catalyst Pick up a popsicle stick. Take out and turn in HOMEWORK in the front bin. Sit in a seat SILENTLY.

2. Do Now… Write your first and last name on the popsicle stick Ms. Wagner

3. Agenda Notes #4: The Moon – Satellites – Moons (phases, eclipses, tides) Simulation Sun, Earth, Moon models Exit Ticket

4. I can explain the moon and its effect on the Earth.

5. Satellites Satellites are used to get information about Earth from above the Earth’s surface

6. Orbit Orbit = elliptical path around earth Elliptical =

7. Satellites Satellite = Object placed into orbit The only naturally occurring satellite around Earth is the moon. Earth is a satellite planet of one particular star, sun There are 13,000 satellites orbiting around earth!

8. Satellites 1.Navigation satellites (GPS) 1.Weather satellites 1.Earth observation Emmitter Receiver

9. Moon Orbits earth Extremely dry – no indigenous water No atmosphere Little surface gravity http://video.nationalgeographic.com/video/ 101-videos/moon-101-sci http://video.nationalgeographic.com/video/ 101-videos/moon-101-sci

10. Moon Phases Reflection from sun’s light rays Depends on the position around the earth and the reflection of the suns light Half the moon is always lit by the sun, as it orbits we see different parts of the lighted area. Moon rotates around the Earth in 29 days – http://aa.usno.navy.mil/graphics/Moon_movie.gif http://aa.usno.navy.mil/graphics/Moon_movie.gif

11. Moon Phases The same side of the moon faces the Earth because its period of rotation about its axis and its revolution around the Earth are about the same. Only ever seen 1 side of the moon

12. Moon Phases

13. Moon Phases: 1.New Moon 2.Waxing Crescent 3.First Quarter 4.Waxing Gibbous 5.Full Moon 6.Waning Gibbous 7.Third Quarter 8.Waning Crescent

14. Moon Phases Waxing – lighted portion of the moon increases – Waxing a car Waning – lighted portion of the moon decreases – lil wayne = little

15. Eclipse Earth, Sun and Moon line up – solar eclipse, we see the Sun blocked out Sun -> moon -> earth – lunar eclipse, we see a shadow on the Moon Sun -> earth -> moon

16. Solar Eclipse

17. Lunar Eclipse

18. Making History SUPERMOON LUNAR ECLIPSE http://solarsystem.nasa.gov/planets/moon

19. Brain Break Try to snap your fingers while winking the opposite eye – Snap with the right hand while winking the left eye Snap with the left hand while winking the right eye

20. Tides The periodic rise and fall of the water level in the oceans and other large bodies of water Caused by the gravitational pull of the moon – Because liquids move more easily than solids.

21. Tides High tide – Water bulges towards the moon (opposite side too) Low tide *** 2 high tides and 2 low tides a day***

22. Tides Neap tide – Moderate tide heights sun, Earth, and moon form a 90 degree angle Spring tide – Extreme tide heights (low low tides and high high tides) Sun, Earth, and the moon are aligned

23. Tides

24. Rotation and Revolution Earth rotates around a 23.5 degree angle Axis Revolution is caused by the gravitational pull from the sun

25. Rotation and Revolution

26. Agenda Notes #4: The Moon – Satellites – Moons (phases, eclipses, tides) Simulation Earth, Sun, Moon Model Exit Ticket

27. Tides Simulation Students get into a circle and link arms water on earth 1 student acts as the moon As the moon moves around the earth, the water is pulled towards the moon causing low and high tides – Students bend towards the moon as the moon orbits the circle Simulating the waters movement

28. Sun, Earth, and Moon Model

29. QUESTIONS??

30. EXIT TICKET

32. Homework Design a page for a middle school science book describing the moon’s effect on the Earth’s tides. Explain in simple terms how the Moon effects the tides. Include a sketch with labels and a caption.
