more gravity
During which season does the Sun have the lowest path across the sky?
winter
Water freezes at what temperature Celsius?
0 degrees
How long does it take the Earth to complete one revolution around the Sun?
365 days
Where did the word moon come from?
moonth (month)
Less massive planets and moons have ____ gravity.
Less gravity
During which season does the Sun have the highest path across the sky?
summer
Water boils at what temperature Celsius?
100 degrees
The Earth's rotation gives us what?
day and night
How long does it take the moon to go from no moon to full moon?
Gravity pulls all objects where?

Why are we only able to see certain constellations at certain times of the year?

What would happen if the Earth spun on its axis twice as fast?
Days and nights would be shorter (half as long)
Can you ever see the Moon during the day? Why or why not?
If you go visit a new planet, what could you do to test to see if the planet has more or less gravity than Earth?
You could try to jump on the new planet. If you can jump higher, than the planet has less gravity. If you can't jump as high, there is more gravity.
If a photo was taken around 12:00 noon, and the shadows in the picture are very short, what inference can you make about which season the photo was taken during? Why?
Summer- there are short shadows during the middle of a summer day because the Sun is directly overhead, causing the shadow to be directly below the object.
