| Control Group | part of an experiment treated "normally" -- used to compare experimental results |
| Hypothesis | untested idea, an educated guess - properly phrased as a statement of what may be true |
| Theory | idea in science with at least some evidence or observations supporting it, useful in making predictions and guiding experimentation |
| Direct Observation | an observation made on something you can see or measure "firsthand" |
| Indirect Observation | observation about something you can't see or measure "firsthand" -- you must observe HOW OTHER THINGS ARE AFFECTED |
| Law | idea in science has always been proven correct repeatedly without exception (it may be modified or changed in the future, though this is unlikely) |
| Inference | a conclusion or explanation based on observations made about something |
| Scienctific Method | steps often used in solving problems in science (can be helpful in solving any problem) |
| Experiment | used to test a hypothesis |
| Procedure | something DONE in an experiment |
| Science | search for the true nature of the world and how it works based on our observations of it |
| Independent Variable | Something you change to observe and effect. The cause in an experiment. |
