How do the sizes of the inner planets (4 closest to the sun) compare to the sizes of the outer planets (4 farthest from the sun)?
The inner planets are larger.
The outer planets are smaller.
There is no size difference between the inner and outer planets.
The inner planets are smaller.
Describe how the distances between the orbits of the inner planets (1st four from the sun) compare to the distances between the orbits of the outer planets (four farthest from the sun).
The distances between orbits of the outer planets are much smaller.
The distances between orbits of the outer planets are much larger.
The distances between orbits of the inner planets are much larger.
There is no difference between the distances of the orbits of the inner planets and the outer planets.
This model shows...
the size differences among the planets accurately.
the distances between the planets accurately.
both the sizes of the planets and the distances between them accurately
What is the center of our solar system?
The sun
Uranus
Jupiter
Saturn
Our Solar System_________
Has 8 planets that are very close together
Has 8 planets, but is mostly empty space
Has 9 planets that are very close together
Has 9 planets, but is mostly empty space
Why do scientists use scale models to study the Solar System?
The solar system is too large to study without using models
The solar system is too small to study without using models
Scientists don't need to use models because we have satellites
All of these options are true
Why is making a model of the solar system difficult?
Don't have the right materials
The solar system is so big and the objects in it are so small in comparison
There are too many parts in a model
Because the science concepts are too difficult
If you were going to make a scale model of the Solar system what planet should be the second largest?
Jupiter
Saturn
Earth
Uranus

both would hit at the same time
What keeps the planets in orbit around the sun?
gravity
friction
density
distance
When will the forces of gravity between two objects be the GREATEST?
when the masses of both objects are small and the objects are far apart
when the masses of both objects are large and the objects are close together
when the masses of both objects are small and the objects are close together
when the masses of both objects are large and the objects are far apart
When will the gravity between two objects be the LEAST?
when the masses of both objects is small and the objects are close together
when the masses of both objects is small and the objects are far apart
when the masses of both objects is large and the objects are close together
when the masses of both objects is large and the objects are far apart
A boy throws a baseball up in the air. Why does the baseball fall back down to the ground?
the mass of the baseball decreases, causing it to fall
the weight of the ball causes the ball to fall
the force of gravity causes the ball to fall
the density of the ball causes the ball to fall
Which statement about gravity is true?
gravity causes objects to pull towards one another
gravity causes objects to push away from each other
gravity only takes place between planets
the moon doesn't have any gravity
When you drop a hammer and a feather, why does the feather fall slower?
air resistance causes the feather to slow down
gravity pulls harder on the hammer than the feather
gravity pulls harder on the feather than the hammer
air resistance causes the hammer to fall slower
A force is a ...
a pull
a push
a push or pull
none of the above
The force of gravity is related to the masses of objects attracting each other. Which planet do you think has the greatest gravitational force?
Mercury

Neptune
Earth
weight is ...
mass combined with gravitational force
mass combined with size
gravitational force and diameter
mass and volume
