PS 5.1 Craters & Variables Review

What best describes the independent variable?

• The variable that is purposefully changed. It's not affected by any other variables.

• The variable that gets affected.

• The variable that remains constant throughout the experiment.

• The variable that is controlled to be the stay.

A group of students were interested in how the weight of a skateboarder affects his speed. The students pushed a skateboard down a hill with different size weights on it and measured the speed at the bottom of the hill. They were sure to use the same skateboard and hill each time.

What is the independent variable?

• Speed of the skateboarder

• Weight of the skateboarder

• The slope of the hill

• The type of skateboard

How does the size of an impactor object relate to the size of the crater formed?

• As the impactor object size increases then the crater size also increases.

• As the impactor object size increases then the crater size decreases.

• As the impactor object size decreases then the crater size increases

• As the impactor object size decreases then the crater size remains the same.

How does the drop height of an impactor object affect the size of the crater formed?

• As the drop height of the impactor object increases then the crater size decreases.

• As the drop height of the impactor object increases then the crater size also increases.

• As the drop height of the impactor object decreases then the crater size increases.

• As the drop height of the impactor object decreases then the crater size remains the same.
