Down
- 1. Descriptive data
- 2. a testable prediction that attempts to answer a question
- 7. what is being purposely change; what is being tested, the “cause”
- 8. the degree to which measurements agree with one another
- 9. what is being measured the data collected as a response, the “effect”
- 11. description of how things happen in nature
- 13. Find the temperature of an unknown substance
- 14. used for performing small chemical reactions
- 15. Factors that don't change in the experiment, conditions kept the same for all groups
