Across
- 2. is a simplified representation of a phenomenon. Scientists use models to understand, explain, and predict how things work.
- 4. Models: these are 2-dimensional flow chart, diagrams and infographics that show how things work or relate to each other.
- 6. Models: these are 3-dimensional and tangible (you can touch and/or hold it) . Examples: A Globe or Solar System Model
- 10. Proportional: when x doubles, y halves. (As x increases, y decreases)
- 12. Variable:This is the part of an experiment or investigation that you change to see if it has an effect.
- 13. Error: created by unknown and/or uncontrolled variables or uncertainties
- 15. is the random error that comes from measurement
- 17. aka “gross” errors created by carelessness, ignorance or thoughtlessness
- 18. how close a series of measured values are to each other.
Down
- 1. When x doubles, y quadruples (As x increases, y increases at an a faster rate)
- 2. Models: equations and data that represent a relationship or system.
- 3. how close a measured value is to the actual or expected value.
- 5. Variable: This is the part of an experiment or investigation that you are measuring or recording
- 7. is the “spread” of numbers of in a number set.
- 8. Line: When x doubles, y stays the same. (As ex increases, y stays constant)
- 9. Error: cause by condition of the instruments and/or environment. These errors are usually consistent
- 11. is the “central” number of a number set
- 14. Variable: This is the part of an experiment or investigation that you keep constant.
- 16. When x doubles, y doubles (As x increases y increases at a constant rate)
