Across

3. distance traveled divided by time with direction specified.

4. a measurement that includes both magnitude and direction.

6. the base unit for distance in the metric system

7. the variable during an experiment that only changes in response to another change.

9. the part of an experiment that does not receive treatment and is used as a benchmark for comparison

11. the base unit for time in the metric system

12. the part of an experiment that receives the variable being tested.

13. a statement that is always true under defined conditions.

15. a well-tested explanation that matches observations and is confirmed through repeated experimentation.

Down

1. distance traveled divided by time taken, no direction specified

2. a tentative explanation that serves as the basis for an experiment
