  1. THE PROCESS OF SCIENCE • The word science is derived from a Latin verb meaning “to know” • Science developed from our curiosity about ourselves and the world around us

  2. The Process of Science: "The Scientific Method"

  3. What’s a Scientific Question? • Scientific Questions are….

  4. What’s a Hypothesis? • Tentative, but untested explanations • Make predictions that can be tested

  5. How do you test a Hypothesis? • Via controlled experiments or pertinent observations • Kinds of variables:

  6. Experiments of classical design • Individuals studied divided into two groups • Experimental group • Control group

  7. How does science really work in today’s world? • Exhaustive literature search + observations   hypothesis • Prediction • Write a proposal, design experiment • Get money $$$$$ • Revise proposal based on $$$ • Experiment/collect data • Statistics • Write manuscript of results • Publish or perish

  8. Observation Fact LAW • A fact leads to a law, eventually. • What is a law?

  9. What happens if all of our experiments fail to negate our hypothesis? • What if workers in other parts of the community, county, state, country, or world also fail to negate your hypothesis?

  10. Theory • Definition: Observations LAW Hypothesis Experimentation Theory

  11. Finished? • How long do theories last?

  12. To Prove or Not to Prove • Experimentation can either support or reject a hypothesis. • Experimentation can never prove a hypothesis 100% correct. – why? • After each each experiment we need to re-evaluate our results and observations to either make changes in our hypothesis or more likely design a new experiment.
