  1. Observation: • Process of using your senses to gather information

  2. Inference: • Drawing a conclusion or making a logical judgment on the basis of circumstantial evidence and prior conclusions rather than on the basis of direct observation 

  3. From Observation to Scientific Law

  4. Observation to Scientific Law • Observation • Hypothesis • Theory • Scientific law

  5. Observation • Process of using your senses to gather information

  6. Examples of Observation? • Aristotle • Heavier objects fall faster than lighter objects • Tadpoles and frogs form from pond mud • Earth is the center of the universe • Maggots spontaneously form from rotting meat

  7. Hypothesis • “Testable Prediction” • A proposed solution to a problem • How could we test the previous “observations”?

  8. Examples of a Hypothesis • Heavier objects fall faster than light objects? • If two objects of different masses are dropped, then…? • Tadpoles form from pond mud? • If pond mud is given enough time, then…? • The Earth is the center of the universe • ??? • Maggots spontaneously form from rotting meat? • If meat is left to rot, then…?

  9. Theory • Explanation based on many observations supported by experimental results • “Tells Why”

  10. Examples of Theories • Theory of Plate Tectonics – 1960’s • Big Bang Theory – 1930’s • Theory of Relativity – 1900’s

  11. Scientific Law • “Rule of Nature” • Describes a Pattern • Says what will happen but does not need to tell why

  12. Examples of Scientific Laws • Newton’s Laws of Motion – 1600’s • Kepler’s Laws of Planetary Motion – 1600’s • Boyle’s Law – 1700’s • Charles’s Law – 1700’s

  13. The Six Steps of the Scientific Method

  14. Step #1 • Determine Problem “What is it that you are trying to figure out?”

  15. Step #2 • Research Problem • Gather as much information as possible to help you make an “educated guess” about the problem

  16. Step #3 • Form a Hypothesis “What do you think will happen?”

  17. Step #4 • Test the Hypothesis “Design and conduct an experiment which will attempt to answer your hypothesis”

  18. Step #5 • Record and Analyze Data “Take careful notes of your experiment!” “Then take a close look at your notes!”

  19. Step #6 • Form a Conclusion “Does your data support / not support your hypothesis?” - If it does, accept your hypothesis - If it does not, reject your hypothesis

  20. The Scientific Method • 1. Determine the Problem • 2. Conduct Research • 3. Form a Hypothesis • 4. Test the Hypothesis • 5. Record and Analyze Data • 6. Form a Conclusion

  21. Tadpoles and frogs in pond

  22. Maggots on meat

  23. Wheat + Shirt = Mice!

  24. Where do horses come from?

  25. Moving Stars!
