| Hypothesis | An educated guess about an experiment |
| Independent variable | The variable changed by the experimenter; the cause |
| Dependent variable | The variable that changes because of the IV, the effect |
| Control group | The group in the experiment that has no IV, so you can compare to it. |
| Verifiable data | Data that others can produce as well. |
| Bias | Being one sided; unfair |
| Scientific notation | The way to write very large or small numbers |
| Law | A description of a natural phenomenon; potentially an equation |
