2 Sun, Earth, and Moon Presented by Dr. Marjorie Anne Wallace Elementary Science Resource Teacher

3 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?

4 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.

5 We breathe: 78% nitrogen 21% oxygen 1% argon, neon, carbon dioxide, neon, & krypton

6 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

7 Answer: Sun, Earth, then moon The sun is the largest Next in size is the Earth. The moon is smaller than the Earth.

8 2000 SOL #4.7 Which of these is the biggest? FThe moon GThe Earth HThe sun JJupiter

9 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.

10 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

11 2001 SOL 3.7 & 4.7 The moon revolves around - Fitself Gthe Earth Hthe sun Jthe solar system

12 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.

13 Earth Science Question: rotation What is rotation? (define) The rotation of the Earth on its axis causes- Adays Bmonths Cseasons Dyears

14 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).

15 Earth Science Question: Which of these shows the location of a polar ice cap? Which of these shows the location of the equator?

16 Polar ice caps= A Equator= C

17 Which of these is caused by the turning of the Earth? FSummer and winter GStars HDay and night JMoon phases

18 The turning of the Earth causes Day & Night

19 When the moon is seen from the Earth as a whole circle, it is called a- ACrescent moon BFull moon CHalf moon DNew moon

20 When the moon is seen from the Earth as a whole circle, it is called a FULL MOON.

21 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

22 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.

23 The revolution of the Earth around the Sun takes- Aa day & night or 12 hours Ba week or 7 days Ca month or days Da year or 365 days

24 The revolution of the Earth around the sun Takes 365 days or one year. NOTE: Due to the tilt of the Earths axis during revolution, the Earth experiences seasons.
