Scientific Method

Correctly Order the following Steps of the Scientific Method

• Collect Data

• Draw Conclusions

• Ask a question

  (Problem)

• Create a Hypothesis

• Preform an Experiment

Control Group

• The group that is being given normal/known conditions

• A group of people who control the experiment
• A group of people who are in control of the situation
• The group that is being tested in the experiment

Experimental Group

• A group that is not exposed to the treatment
• A group that is exposed to the treatment
• A group that is used for comparison
• A group that is not part of the experiment

Independent Variable

• A variable that depends on other factors
• A variable that stays the same

• A variable that is always constant
• A variable that is changed by the scientists

Dependent Variable

• A variable that depends on the other (The data collected after a change is made)

• A variable that stays the same

• A variable that is constant
• A variable that the scientists changes

Constants

• Factors that remain the same in the experiment

• A variable that changes in the experiment

• The prediction of the experiment

• A data type collected in the experiment

Hypothesis

• A statement that might be true, which can then be tested
• A proven scientific fact
• A question that scientists ask
• An answer to a scientific question

What is a controlled experiment?

• An experiment to test the effect of a single variable

• An experiment that is conducted under strict supervision
• An experiment that does not have any variables

• An experiment to test the effect of a dependent variable

How do we draw conclusions?

• Make up answers you think are correct

• Ask more questions to be answered

• Use that data from the table

• Support your hypothesis always

How do we increase the validity of an experiment?

• Repeat (More Trials)

• Have a large sample size

• Be sure there is a control group

• Only change a single variable
