  1. The Scientific Method …lots and lots and lots of math. ……….just kidding

  2. Goal • What is science? • What is the scientific method? • Does the scientific method work?

  3. What is science? • Science is a tool to understanding the Universe. • You see something happen, you ask why? • You make a model (or hypothesis) that explains what you see. • A scientific model must do two things: • Explain what is seen. • Predict what will happen accurately. • How do you know if your model is right?

  4. model test The Scientific Method • Observe an event. • Formulate a question • Develop a model (or hypothesis) which makes a prediction. • Test the prediction. • Observe the result. • Analyze the data • Revise the hypothesis. • Repeat as needed. • A successful hypothesis becomes a ScientificTheory.

  5. Medical Science

  6. Everyday Science

  7. Everyday Science

  8. Food Science • Throwing something together  Hypothesis • Your grandmother’s time-tested recipe  Scientific Theory.

  9. Recap: Theories, Guesses, Laws • What does the word “Theory” mean to you? “A conjecture; guess” (Webster’s Dictionary) • Does it mean the same to a scientist? “A model which has been born out by repeated tests and observation. An Explanation”

  10. Theories • So: a theory is a highly successful hypothesis. • All hypotheses make predictions. • All theories make predictions. • All theories can be tested. • Result: Any scientific theory is subject to change as our ability to make tests, or make observations of a test’s results, improves with time.

  11. Non-scientific Theories • Make no predictions • Un-testable • Can’t be falsified • The chain of events needed for life to arise is too complicated to have happened by chance, a divine intelligence must therefore have caused life to arise (Intelligent Design).

  12. Non-scientific Theories • Car won’t work?  Aliens drained the battery. • Spaghetti is bland?  You were meant to eat bland food. • Car won’t work?  Gods must be angry. • Spaghetti is bland?  At the instant of tasting, tongue is transported to alternate dimension where all flavors are rendered nullified. Happens instantaneously.

  13. Scientific Laws • A general statement about the relationship of natural quantities which has been time tested and has not been contradicted. • Examples: laws of conservation of matter and energy. Newton’s laws of motion • Usually has a mathematical support associated with it.
