What is the purpose of a control in an experiment?

• To change the outcome of the experiment

• To evaluate whether an experiment is working

• To introduce new variables

• To make the experiment more complex

What is one way to ensure the reliability of experimental data?

• Performing tests multiple times

• Using different materials each time

• Changing the procedure each time

• Only performing the test once

Why should detailed notes be taken during an experiment?

• So the experiment can be repeated by someone else

• To make the experiment look more professional

• To impress the teacher

• To fill up the journal

How can the reliability of experimental data be increased?

• By performing tests multiple times

• By using different materials each time

• By changing the procedure each time

• By only performing the test once
