Vocabulary #1 (The study of life)

Definitions:

1. biology: the scientific study of living and nonliving organism.
2. light microscope:  microscope consisting of an optical instrument that magnifies the image of an object.

10. hypothesis: a statement that can be tested.
11. experiment: testing an hypothesis using a series of steps with controlled conditions.
12. variable:  something that causes the changes observed in an experiment.
13. control: a standard for comparing results.
14. data: recorded facts or measurements from an experiment.
15. theory: a hypothesis that has been tested again and again by many scientists, with similar results each time.
16. technology: the use of scientific discoveries to solve everyday problems.
