Why do scientists use the scientific method?

• To make sure they get credit for their discoveries.

• To make sure their results are valid and can be performed by other scientists.

• So that other scientist don't get mad at them

How are EXPERIMENTAL and OBSERVATIONAL investigations similar?

• They both require a question that can be researched, a hypothesis and procedures.

• They both require a question that can be researched, procedures and a conclusion

• They both require a hypothesis, and procedures.

How are EXPERIMENTAL and COMPARATIVE investigations different?

• * EXPERIMENTAL requires control / control group.

  * COMPARATIVE does not require control / control group.

• * EXPERIMENTAL requires variables .

  * COMPARATIVE does not require variables.

Scientists have several ways for evaluating the validity of experimental results. Which of the following is a characteristic shared by all valid scientific investigations?

• The experiments must be long.

• The experiment must produce replicable results.

• The experiment must yield the desired results.

• The experiment must be complex.
