• Hypothesis

• Observation

• Theory

• Conclusion

The following statement is an example of what part of the scientific method? "If there is a relation between listening to music and heart rate, then listening to music will cause a person's resting heart rate to either increase or decrease."

• Theory

• Observation

• Question

• Hypothesis

The variable in an experiment that is being tested.

• Independent variable

• dependent variable

• controlled variable

• lab variable

The variables in an experiment that are different from one another; they are changed as part of the experimental investigation.

• independent variable

• dependent variable

• controlled variable

• lab variable

The variable that is held constant/consistent/is not changed; used to compare with the changed variables.

• independent variable

• dependent variable

• control variable

• lab variable

The group of variables that are being used to test the hypothesis in an experiment.

• experimental group

• control group

• data group

• lab group

The group of variables that are not changed and are used to compare with the independent variables.

• experimental group

• control group

• data group

• lab group

This type of data is based on measurements that have numerical value. (i.e. mass, length, volume, velocity...)

• qualitative data

• quantitative data

• super data

• lab data

This type of data is based on descriptions such as color, shape, texture, etc...

• qualitative data

• quantitative data

• super data

• lab data

An event that occurs in nature that may or may not be fully explained using the scientific method.

• natural episodes

• natural laws

• natural selection

• natural phenomena
