2. A parabolic relationship that results when one variable depends on the square of another variable.
3. The factor that is changed or manipulated during an investigation.
7. A representation of an idea, event, structure, or object to help people better understand it.
9. A characteristic of a measured value that descries how well the results of a measurement agree with the "real" value, which is the accepted value, as measured by competent experimenters
10. An explanation of things or events based on knowledge gained from many observations and investigations.
11. A hyperbolic relationship that exists when one variable depends on the inverse of the other variable.
13. A comparison between an unknown quantity and a standard.
15. All the valid digits in a measurement, the number of which indicates the measurement's precision.
16. The factor in an investigation that depends on the independent variable
17. A relationship in which the dependent variable varies linearly with the independent variable.

1. The patterns of investigation procedures.
4. A method of treating units as algebraic quantities that can be cancelled; can be used to check that an answer will be in the correct units
5. A possible explanation for a problem using what you know and what you observe.
6. A statement about what happens in nature and seems to be true all the time.
8. A line drawn on a graph as close to all the data points as possible; used to describe data and predict where new data will appear on the graph.
12. The branch of science that studies matter and energy and their relationships.
14. A characteristic of a measured value describing the degree of exactness of a measurement.
