Transcript

  • 1. Sun , Earth, and Moon Presented by Dr. Marjorie Anne Wallace Elementary Science Resource Teacher
  • 2. I bet you know the answers!
    • What causes day & night?
    • Which one is bigger the earth or the moon?
    • Where does the moon get its light from?
    • What percent of the earth is always lit by the sun?
    • How many stars are in our solar system?
    • How many days does it take for the Earth to revolve around the sun?
    • How many low and high tides on Earth every 24 hours?
  • 3. The Earth:
    • -is the third planet from the Sun,
    • -is an oblated sphere,
    • -rotates on its imaginary
    • axis counterclockwise every
    • 24 hours or 1 day,
    • -appears blue in space
    • because it is 70% water,
    • -revolves around the sun every
    • 365 days or 1 year.
  • 4. We breathe:
    • 78% nitrogen
    • 21% oxygen
    • 1% argon, neon, carbon dioxide, neon, & krypton
  • 5. Which one is the smallest? Which one is the largest?
    • Can you put these in size order?
    • Place the following in order from largest to smallest.
        • Moon
        • Sun
        • Earth
  • 6. Answer: Sun, Earth, then moon
    • The sun is the largest
    • Next in size is the Earth.
    • The moon is smaller than the Earth.
  • 7. 2000 SOL #4.7
    • Which of these is the biggest?
    • F The moon
    • G The Earth
    • H The sun
    • J Jupiter
  • 8. Answer: H The sun is the largest! Our sun is the only star in our solar system. The sun is also the largest heavenly body in our solar system.
  • 9. Earth Patterns,Cycles, and Change - SOL 3.7, 4.7
    • The sun heats the Earth unevenly, making the poles cold and the tropics hot, because-
    • A the tropics face more directly
    • toward the sun
    • B the poles are covered with ice
    • which causes cold air
    • C seasons change
    • D weather changes
  • 10. 2001 SOL 3.7 & 4.7
    • The moon revolves around -
      • F itself
      • G the Earth
      • H the sun
      • J the solar system
  • 11.
    • The moon revolves or orbits the Earth once every 29 days.
    • We all ways see the same side of the moon because the moon rotates and revolves at about the same speed.
  • 12. Earth Science Question: rotation
    • What is rotation? (define)
    • The rotation of the Earth on its axis causes-
      • A days
      • B months
      • C seasons
      • D years
  • 13. Rotation causes day & night.
    • Rotation is the turning or spinning of the Earth in one place on its imaginary axis.
    • Rotation of the earth on its axis causes day & night. (answer A).
  • 14. Earth Science Question:
    • Which of these shows the location of a polar ice cap?
    • Which of these shows the location of the equator?
    B A C C D
  • 15. Polar ice caps= A Equator= C 0º latitude 90º latitude
  • 16. Which of these is caused by the turning of the Earth?
      • F Summer and winter
      • G Stars
      • H Day and night
      • J Moon phases
  • 17. The turning of the Earth causes
    • Day & Night
  • 18. When the moon is seen from the Earth as a whole circle, it is called a-
      • A Crescent moon
      • B Full moon
      • C Half moon
      • D New moon
  • 19. When the moon is seen from the Earth as a whole circle, it is called a FULL MOON.
  • 20. Which of these is the next phase of the moon?
    • New Moon --- Waxing Crescent --- ?
    • F Full Moon
    • G Waning Crescent
    • H First Quarter
    • J Waxing Gibbous
  • 21. The next major phase of the moon would be…
    • First quarter.
    • Just think about it…the
    • New moon (can only get bigger. Or = Waxing)..
    • Then comes Waxing crescent …next is
    • First quarter …then
    • Waxing Gibbous and then a
    • Full Moon .
  • 22. The revolution of the Earth around the Sun takes-
      • A a day & night or 12 hours
      • B a week or 7 days
      • C a month or 29-31 days
      • D a year or 365 days
  • 23. The revolution of the Earth around the sun
    • Takes 365 days
    • or one year.
    • NOTE:
    • Due to the tilt of the Earth’s axis during revolution, the Earth experiences seasons.
