Ms. S set up an experiment to see how the mass of a ball affects the distance it rolls off a ramp. What is the dependent variable?

• Distance traveled by the ball
• Height of the ramp
• Mass of the ball
• Where the experiment took place.

The control group in an experiment is the

• point at which observations are made.

• one that does not receive any experimental treatment.

• careful measuring and recording of data.

• point at which variables are made.

Thinking that it is going to rain when you see dark clouds in the sky is a (an)

• variable

• theory

• inference

• observation

Science should be based on

• feelings

• observations

• opinions

• faith

Which of the following is an example of an observation?

• My favorite food is French fries.

• The frog has brown stripes on its back.

• The insect was lonely so it flew away.

• Biology is the best class ever.

An inference is

• the same as an observation

• a way to avoid bias

• a statement involving numbers

• a logical interpretation of an observation

A variable in an experiment that the scientist deliberately changes (manipulated).

• Dependent variable
• Independent variable
