- 6. a possible explanation for an observation that can be tested by scientific investigations
- 9. uses numbers to describe what is observed
- 10. the internationally accepted system of measurements
- 11. the factor that you want to test changed by the investigator to observe how it affects a dependant variable
- 12. the investigation and exploration of natural events and of new information that results from those investigations.
- 13. any factor that can have more than one value
- 14. a rule that describes a repeatable pattern in nature
- 17. the factors in an experiment that don't change
- 18. the expression of error as a percentage

Down
- 1. comparing what you know with the info you are given in order to decide weather you agree with it
- 3. uses words to describe what is observed
- 4. a method of writing or displaying very small or very large values in a short form
- 5. a statement of what will happen next in a sequence of events.
- 7. an explanation of observations or events that's based on knowledge gained from many observations and investigations
- 8. a spoken or written summary of observations
- 11. a logical explanation of an observation that is drawn from prior knowledge or experience
- 15. contains the same factors as the experimental group but the independent variable is not changed
- 16. used to study how a change in the independent variable changes the dependant variable
