This is the "glue" that keeps all planets rotating in an orbit
Gravity

Our moon's size compared to Earth.
It is smaller. About 1/6 the size.

Why does the earth experience night and day?
The earth rotates on its axis. While half the earth is always lighted, half is not. We spin from darkness into light and back again.
200
The motion (movement) of one celestial body around another.
revolution
200
An imaginary line that encircles the widest part of any planet.
equator

Draw (on the board) the position of the sun, the moon, and the earth during a solar eclipse.
I'll tell you if you are correct!

Why does the sun appear to move across the sky?
It's a perspective thing! The sun remains central as we spin into it (and then away). As we spin, it appears to rise in the sky. This is a similar experience to watching a person appear to move as you go around a merry go round.

The imaginary line by which a planet rotates
Axis

These rock like objects orbit around the sun. Most are between Mars and Jupiter.
asteroids
300
What phase immediately follows a new moon.
Waxing crescent.

Why do parts of Alaska experience nearly 24 hours of daylight in the summer.
The northern hemisphere is tilted toward the sun in the summer time. As the Earth rotates on its axis, the northern portion of the hemisphere never spins into darkness.

The inner planets are terrestrial planets. This means they are mainly solid. What are the terrestrial planets?
Mercury, Venus, Earth, and Mars
400
With a bright tail, this is often called a dirty snowball.
Comet

You see a cresent moon on the left side of the moon. What type of crescent moon is this?
Waning crescent

During a lunar eclipse, the moon is blocked from the sun's light. Draw a picture on the board of the sun, the earth, and the moon during this type of eclipse.
I will tell you if you are correct.

The sun's distance from Earth changes due to the oval orbit of Earth around the sun. What is the average distance of earth from the sun?
93 million miles
500
The amount of tilt our planet experiences as it revolves around the sun.
23 and 1/2 degrees

During a new moon, the moon is not visible at all.
Draw a picture of the moon, sun, and earth when the moon is in this position. Place it on the board.
I will tell you if you are correct.

You weigh 120 pounds here on earth.
How much would you weigh on the moon? Why?
20 pounds. This is due to the fact that the moon's gravitational pull is not as strong as the pull here on earth.
