Sun-Earth-moon System

Earth

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??

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

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?

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

Seasons Solstice=Summer and Winter Equinoxes= Fall and Spring

The moon Why does the moon shine???

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)

The Moon A visual of the moon phases:

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!!

What are some Causes of eclipses? Solar Eclipse? vs Lunar Eclipse? The moon Eclipses What are some Causes of eclipses? Solar Eclipse? vs Lunar Eclipse?

The moon Solar Eclipse

The moon Lunar Eclipse

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

Where did the moon come from??

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

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?

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.

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

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!!

Extension Moon and Earth tides http://studyjams.scholastic.com/studyjams/jams/science/weather- and-climate/tides.htm

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.

I’m thinking of a word…. Review Ideas Earth, Sun, and Moon Crescent vs Gibbous Axis Eclipse Rotation Solar vs Lunar Revolution Tides Seasons Currents Solstice vs Equinox Phases Waxing vs Waning
