| controlled experiment | an experimnet where all variables are controlled for except one, allowing the experimenter to observe the effect of that one variable. |
| length of the pendulum | determines the number of swings in a unit of time |
| graphs | can be used to display results |
| capacity | the maximum volume of fluid a container can hold |
| two-coordinate graph | displays the relationship between the independent and dependent variables in an experiment |
| system | a set of related objects that can be studied in isolation |
| multiple trials | adds validity to results |
