| Scientific Method | ||
| #1 | What is the first step of the scientific method? | Ask a question |
| #2 | What should you do after you form a conclusion to increase the validity of the experiment? | Re-test, repeat the experiment several times |
| #3 | Which variable is measured and observed? | Dependent Variable |
| #4 | How does the CONTROL GROUP setup in an experiment differ from the other setups in the same experiment? | It does not receive the experimental treatment (Independent Variable). |
| #5 | What is an independent variable? | The variable being tested. |
