| Part of the experiment that is changed or manipulated (only one can be changed); the “if” part of your hypothesis | independent variable |
| Used as a comparison in the experiment for seeing if the change you make in the I.V. is the D.V.’s predicted result. | control |
| Factor which changes in a scientific investigation | variable |
| The parts of the experiment that stay the same throughout every trial. | constant |
| The result of the experiment that may change as a result of manipulating the independent variable; the “then” part of your hypothesis; DV = data | dependent variable |
| Determine what information is given by data collected (graphs and tables) | analyze |
| The answers to your problem, answers your hypothesis. | conclusion |
| Doing the experiment at LEAST three times to make sure that the results are accurate. | repeated trials |
| The written summation of an experiment | conclusion |
| Measurement of the dependent variable | data |
| What you are trying to solve or figure out. | problem |
| Testing your hypothesis. | experiment |
| The step-by-step directions for the experiment. | procedure |
| Visual representation of information or data | graph |
| A logical interpretation based on observations and prior knowledge | inference |
| Parts of an experiment that must be kept the same so that they cannot cause a change in the experiment | controlled variables |
| What happens when you are trying and learning | mistakes |
| What must be done in order for an experiment to be considered valid | repeated trials |
