1. Bellwork – List 5 observations

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

3.  Today I will differentiate between scientific theories and laws

4.  Lets look at last week’s learning targets.

5.  Accuracy vs. Precision Accurate and precise Precise

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

8. E = mc 2 Einstein’s theory of relativity

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

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

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