| Hypothesis | Prediction in an experiment. Is tested in an experiment. |
| Independent variable | Changed by the researcher. Is the CAUSE in an experiment. |
| Dependent variable | The EFFECT in an experiment. The results or outcome of an experiment. |
| Graduated cylinder | Measure liquids (usually in mL or L). |
| Thermometer | Measures temperature (C or F) |
| Balance or scale | Measures mass (grams-g) |
| Sample size | Number of individuals in an experiment. Should be large, especially with human experimentation. |
| Repeat trials | Redoing the experiment. Helps to check data to make sure that it is valid. |
| Valid | Accurate and precise. What data needs to be so it can be used. |
| Verifiable | Data is accurate after being checked. Checked through repeat trials and repeatable procedures. |
| Control | Used as a comparison. Does NOT have what is tested. |
| Controlled variables | All variables for all samples are exact copies EXCEPT what is tested. Improves validity. |
| Dissecting tools | Examine internal anatomy of an organism |
| Microscope | Examine very small organisms |
| Ruler | Used to measure length |
| Testable question | Can be answered through experimentation or observation. |
| Conclusions | Statements that summarize results and refer to hypothesis. Made AFTER experimentation and data analysis. |
