Quantity that can have more than a single value, can cause a change in the results of an experiment

• control

• constant

• variable

• standard

Factor that changes as a result of changes in the other variables

• dependent variable

• independent variable

• constant

• control

Factor that, as it changes, affects the measure of another variable

• dependent variable

• independent variable

• constant

• control

In an experiment, a variable that does not change

• dependent variable

• independent variable

• constant

• control

Standard used for comparison of test results in an experiment

• dependent variable

• independent variable

• constant

• control

Occurs when a scientist’s expectations change how the results of an experiment are viewed

• society

• bias

• technology

• theory

Can be used to represent an idea, object, or event that is too big, too small, too complex, or too dangerous to observe or test directly
