An organized method or procedure to investigate phenomena, get new knowledge, correct errors and mistakes, and test theories. It consists of making observations, taking measurements, and conducting experiments in order to formulate, test, and modify hypotheses.

What is the Scientific Method?

100

The group in which the experiment is being conducted.

What is the experimental group?

100

Always follow directions. T or F

What is True?

100

The standard system agreed upon by scientists.

What is the Metric System?

752.6 m =_______km

What is .7526 km?

200

The first step of the Scientific Method

What is Determine the Problem/Ask a Question?

200

The group not exposed to the independent variable. This group is separated from the experiment so that the scientist can compare the results to see if the independent variable did in fact have an effect on the experiment.

What is the Control Group?

200

Report all accidents, injuries, and equipment breakage to the instructor before you leave class - T or F

What is False?

200

The prefix that means 1000

What is a hypothesis?

300

The variable that the experimenter changes to test their dependent variable.

What is the Independent Variable?
