What is the error in this experiment?
An experiment can only have ONE VARIABLE.
How many variables can you have in an experiment?

What is a star cluster?
A star cluster is a group of stars held together by their mutual gravitational attraction.
The Moon was created when debris particles were attracted to each other by ______________.
The Moon was created when debris particles were attracted to each other by gravity.
See picture for “Visual 300”.
Based on this data, what can be concluded about the effect of the drop-angle on the size of the crater formed?
The angle does not make much difference in the crater’s size.
Mare would form before a simple crater.
What is a meteorite?
A meteorite is a piece of a meteoroid that hits the ground.
After a small planet-sized object collided with Earth (Impact Theory), many debris particles were blown into space and were held together in Earth's orbit by ________.
Earth's gravity held the particles blown into space after the impact.
See picture for “Visual 400”.
What is arrow “b” pointing to?
Arrow “b” is pointing to mare.
What is the order from smallest to largest: galaxy, solar system, universe.
The order from smallest to largest is solar system, galaxy, universe.
What is a complex crater?
A complex crater has a central peak with ejects thrown out in rays.
What is the Impact Theory?
The Impact Theory is the best theory most scientists use to explain how the moon formed.
See picture for “Visual 500”.
These are two pictures of Jupiter’s moons. The moons are the same age. Why does one moon have more visible craters?
One moon has more visible craters due to fluid material on the inside flowing onto the surface which covers the craters and makes them no longer visible.
What is the order from largest to smallest: galaxy, solar system, universe.
The order from largest to smallest is universe, galaxy, solar system.
What is a nebula?
A nebula is a cloud of gas and dust in space between stars.
What caused a small planet-sized object to collide with Earth?
Gravity caused a small planet-sized object to collide with Earth.
