Bellwork – List 5 observations

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

 Today I will differentiate between scientific theories and laws

 Lets look at last week’s learning targets.

 Accuracy vs. Precision Accurate and precise Precise

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

E = mc 2 Einstein’s theory of relativity

 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

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

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

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