| 10481276419 | Science hypothesis | An educated guess that attempts to explain a scientific law or certain scientific observations | 32 | |
| 10481276420 | Prediction | A statement that forecasts what would happen in a test situation if the hypothesis were true. | 33 | |
| 10481276421 | Model | A pattern, plan, representation, or description designed to show the structure or workings of an object, system, or concept | 34 | |
| 10481276422 | Experiment | A controlled test of a hypothesis in which the researcher manipulates one variable to discover its effect on another. | 35 | |
| 10481276423 | Scientific method | A logical, systematic approach to the solution of a scientific problem | 36 | |

| 10481276425 | Control group | In an experiment, the group that is not exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment. | 38 | |
| 10481276426 | Experimental group | In an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable. | 39 | |
| 10481276427 | Sampling error | An error that occurs when a sample somehow does not represent the target population. | 40 | |
