100
P $100 - What celestial body has the most gravity in our solar system?

E $100 - The Sun is made of hot gas and is the most massive object in our solar system.
200
S $200 - What keeps the Earth in orbit around the Sun?
S $200 - The Sun's gravity and Earth's inertia keep Earth in orbit around the Sun.
200
P $200 - Which motion does Earth make once every 24 hours?
P $200 - Earth makes a rotation on its axis once every 24 hours.
200
A $200 - Where in the solar system can we find the most asteroids? (Where... location... not the name)
A $200 - The most asteroids in the solar system are found between Mars and Jupiter (in the Asteroid Belt).
200
C $200 - List the planets in order starting with the planet closest to the Sun.
C $200 - Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune (My Very Educated Mother Just Served Us Nachos)
200
E $200 - Which motion does Earth make every year?
E $200 - Earth revolves in an orbit around the Sun every year.
300
S $300 - Why does the Moon revolve around the Earth?
S $300 - The Moon revolves around the Earth because the Earth has more mass, therefore more gravity.
300
P $300 - Looking at the the following list of characteristics, which ones describe comets?
1) Composed of ice and rocks
2) Form tails when they pass close to the Sun
3) Orbit the Sun in the same direction as the planets
4) Usually orbit the Sun in a belt between Mars and Jupiter
P $300 - Comets can be described using 1, 2, and 3.
300
A $300 - What science tool, improved by Galileo, that advanced space exploration by allowing humans to see better and farther into space?
A $300 - The telescope advanced space exploration by allowing humans to see better and farther into space.
300
C $300 - Name the inner planets in order starting with the planet closest to the Sun.
C $300 - Mercury, Venus, Earth, Mars
300
E $300 - Name the outer planets in order starting with the planet closes to the Asteroid Belt.
E $300 - Jupiter, Saturn, Uranus, Neptune
400
S $400 - The space shuttle carries astronauts back and forth between Earth and the International Space Station in orbit around our planet. What feature is necessary for the space shuttle to perform its function of getting people off Earth and going into space (think pushes and pulls)?
S $400 - It is necessary that the space shuttle has enough force to overcome gravity. This can be accomplished with rocket boosters/engines.
400
P $400 - The path that planets take as they orbit the center of the solar system is a result of the interaction of what two things (keeps things moving and keeps things together)?
P $400 - The interaction between gravity (keeps things together) and inertia (keeps things moving) is what keeps planets on their orbital paths.
400
A $400 - Explain the difference between rotation and revolution.
A $400 - Rotation is when an object spins on its axis and revolution is when an object moves in an orbit around another object.
400
C $400 - Millions of pieces of rocky material of various sizes orbit the Sun between the orbits of Mars and Jupiter. What scientific term describes one of these pieces?
C $400 - An asteroid is a piece of rocky material that can vary in size and can be found between the orbits of Mars and Jupiter (Asteroid Belt).
400
E $400 - What motion of Earth explains why the Sun appears to move across the sky?
E $400 - Earth's rotation (spinning) explains why the Sun appears to move across the sky.
500
S $500 - The force of gravitational attraction on Earth could be increased by increasing what?
S $500 - The force of gravitation attraction on Earth could be increased by increasing Earth's mass.
500
P $500 - What scientific vocabulary terms can be used to describe the inner planets?
P $500 - The inner planets can be described as having rocky surfaces, solid cores, closer to the Sun, between the Sun and the Asteroid Belt, smaller planets with less gravity than the outer planets...
500
A $500 - What scientific vocabulary terms can be used to describe the outer planets?
A $500 - The outer planets can be described as having gaseous/liquid surfaces, rocky cores, farther from the Sun, between the Asteroid Belt and the end of the solar system, rings for all four, larger planets with more gravity than the inner planets...
500
C $500 - Looking at the the following list of characteristics, which ones describe asteroids?
1) Composed of metal and rocks
2) Form tails when they pass close to the Sun
3) Orbit the Sun in the same direction as the planets

C $500 - Asteroids can be described using 1, 2, and 4.
500
E $500 - Since 1990, the Hubble Space Telescope has been orbiting Earth and sending back images of space for astronomers to view and interpret. What benefits are there to a telescope that orbits Earth?
E $500 - Images are clearer without the atmosphere pollution, no weather to influence when images can be taken, different light spectrums (near-infrared, ultraviolet) can be captured...
