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