Nature of Science
Across
- 3. the factor that is changed by the investigator to observe how it affects a dependent variable
- 4. a model that is used to test a design
- 8. a rule that describes a pattern in nature
- 12. an explanation of observations or events based on knowledge gained from many observations and investigations
- 13. the use of words to describe what is observed in an experiment
- 15. the degree to which something produces benefits compared to its cost
- 17. the application of science and mathematics to solve problems
- 18. a possible explanation for an observation that can be tested by scientific investigations
Down
- 1. a process of comparing the predicted benefits and costs of a solution
- 2. a description of how close a measurement is to an accepted value
- 5. the part of an experiment that contains the same factors as the experimental group, but the independent variable is not changed
- 6. the act of using one or more of your senses to gather information and take note of what occurs
- 7. the use of numbers to describe what is observed in an experiment
- 9. a situation in which you must choose between two things, giving up one in exchange for the other
- 10. the requirements or specifications for a solution to be successful
- 11. the factors in an experiment that remain the same
- 14. limitations put on the design of a solution
- 16. the confidence that can be placed in the truth of specific findings
