1. Sun-Earth-moon System

2. Earth

3. What technology has helped us understand our earth??
Has a Spherical Shape
Evidence? How do we know??
What technology has helped us understand our earth??

4. Axis: The invisible line that Earth rotates upon.
Rotation: The movement of Earth around its axis
Revolution: The movement of Earth around the Sun.

6. Earth Continued Magnetic field/Axis
When you see a compass needle pointing north this is evidence of Earths magnetic field
Is this pole the same as our North pole?

7. What causes changing seasons??.... Model the seasons changing
Earth Continued
What causes changing seasons??....
Model the seasons changing

8. Seasons
Solstice=Summer and Winter
Equinoxes= Fall and Spring

9. The moon
Why does the moon shine???

10. The moon The moon surface reflects the suns light! Phases of the moon
New
Waxing (Right side reflecting)
Gibbous or Crescent
Full
Waning (Left side reflecting)

11. The Moon
A visual of the moon phases:

12. Oreo Phases
Use Oreos to show all the phases of the moon on your groups plate.
Use the plate to label each phase correctly
Check with me when your done.
Enjoy!!

13. What are some Causes of eclipses? Solar Eclipse? vs Lunar Eclipse?

14. The moon
Solar Eclipse

15. The moon
Lunar Eclipse

16. Craters: Depressions on the moon
Maria: lava filled and cooled dark spots where craters once existed

17. Where did the moon come from??

18. The moon
The impact theory: a meteor hit earth, ejected material off, the material orbited, condensed and formed the moon.

21. The moons phases/shadow? Days? Years?
Bell Work
What is the cause for
Earths Seasons?
The moons phases/shadow?
Days?
Years?

22. What do you think may cause the ocean tides and currents?
Ocean Tides & currents
What do you think may cause the ocean tides and currents?

23. Tide: The gravitational pull of the moon and the rotation of the earth, coupled with the centripetal force of the earth, causes two high tides and two low tides throughout the day.

24. Spring and Neap Tide
Spring Tide: Highest of the high tide.. Created when the sun, moon, and Earth align creating a larger gravitational pull.
Neap Tide: Lowest of the low tides… created when the sun, moon, and earth create a 90Degree angle and cancel each others gravitational pull out

25. Lets practice this gravitational pull/motion that causes tides
Balloon Tides 
Lets practice this gravitational pull/motion that causes tides
High tide and low tide 2 X a day!!

26. Reinforcements
deoID=13223 … slightly monotone and 80’s but good info
deoID=20989 more grown up version

27. Extension
Moon and Earth tides and-climate/tides.htm

28. The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon.

29. I’m thinking of a word…. Review Ideas
