  1. Bellwork – List 5 observations

  2. Observations • Use all of your senses. What do you: • See? • Smell? • Hear? • Feel? • Observations only include evidence, NOT what you conclude.

  3. Learning Objective: Today I will differentiate between scientific theories and laws

  4. But first… • Lets look at last week’s learning targets.

  5. Measurements Precise Accurate and precise Accuracy vs. Precision

  6. Theory Vs. Scientific Law

  7. Read page 16 On a separate sheet of paper… In your own words… Explain the difference between a theory and a law.

  8. Is this a theory or a law? E = mc2 Einstein’s theory of relativity

  9. Theory • Explanation of a natural phenomenon • Based on many observations and experiments over time • Not testable • So you can’t disprove it…. • But you may be able to argue against it

  10. Theories Still subject to new experimentation May be modified Considered successful if they can be used to make predictions that are true.

  11. Scientific Law • Newton’s law of gravity • A relationship in nature that is supported by many experiments • Testable • Consistent test results

  12. Can a theory become a law?

  13. Can a law become a theory?

  14. Closing activity On a blank piece of paper, explain in your own words the difference between a theory and a law
