  1. Scientific Method

  2. 1. Identify Problem

  3. Written as a question.No pronouns.

  4. 2. Observations

  5. Any information that comes to us through our 5 senses.

  6. 3. Data

  7. Written & collected observations.Charts, graphs

  8. 4. Hypothesis

  9. Educated guess used to explain our observation. No pronouns, written as a If, Then statement

  10. 5. Experiment

  11. An activity designed to test a hypothesis. Include materials, procedures, & variables

  12. 6. Theory

  13. Tested hypothesis. May be false.May not be proven.

  14. 7. Scientific Law

  15. A theory which is always found to be correct. Universally accepted.

  16. Controlled Experiment

  17. All factors are the same except the one being tested. Made up of two parts.

  18. A. Control

  19. Part that does not get special treatment.

  20. B. Variable

  21. Part that does get special treatment. It causes the change in an experiment. There are different types of variables:

  22. Constant Variable

  23. Factors that stay the same.

  24. Manipulative Variable. Also called the Independent variable. “Cause”

  25. The part you can change or control, a deliberate change.

  26. Responding Variable. Also called the dependent variable. “Effect or Result”

  27. The part that is a result of the change. The change that occurred because of the mv.

  28. Control Group

  29. Used for comparison. Doesn’t receive any treatment.
