| experiment | organized procedure for testing a hypothesis |
| variable | any factor that can change during an experiment |
| dependent variable | factor that responds to changes in an experiment |
| independent variable | factor in an experiment that is manipulated |
| constant variable | a variable in an experiment that does not change |
| control | standard used for comparison of test results in an experiment |
| quantitative observation | set of observations in an experiment in which numerical data is gathered |
| model | can be used to represent an idea, object, or event that is too big, too small, too complex, or too dangerous to observe or test directly |

| plan experiment | develop a set of procedures to test a hypothesis |
| perform experiment | test hypothesis using a set of procedures |
| organize and interpret data | list data gathered in tables and/or graphs |
| conclusion | statement based on results of an experiment performed to test a hypothesis |
