What is the term for the “If ______________, then _____________” statement?

• Hypothesis

• Procedure

• Conclusion

Why should experiments be repeated to have 3 trials?

• To check if the results are the same each time and to make sure they are accurate.

• To make the experiment more difficult and take longer.

• To prove that the experiment will always take more than an hour.

• To ensure that the results are different each time you test.

Why should scientific investigations be replicable by other people?

• To show that only the original scientist can understand the experiment.

• To prove that the experiment is special and cannot be repeated.

• To make the investigation easier for other scientists to understand.

• To ensure that other scientists can get the same results and confirm the findings.

How can the data that you collect from your experiment be represented and explained?

• By only describing what you saw during the experiment.

• By writing a long essay about the experiment.

Why are controlled variables needed in a science experiment?

• Controlled variables help keep the experiment fair by making sure that only the independent variable affects the outcome.

• Controlled variables are used to ensure that all aspects of the experiment are different each time.

• Controlled variables are the main focus of the experiment and should be changed regularly.

• Controlled variables are the things that do not need to be measured or observed during the experiment.
