Syllabus Canvas on-line website Homework: Read chapter one in textbook Find a graph and a use of statistics in the news (bring to class) Think about what you would like to study or research for your semester long science project

  2. Why Science? Biology Week 1 Dr. Thornton OAPB

  4. Why Biology? • A virus like Ebola?

  5. Why Biology? • BSE causative agent (called a prion) is a protein that is folded in the wrong way

  10. Biology • Study of life • Includes • Physics • Chemistry • All systems • Habitats • Cells • Atoms

  11. Characteristics of Living things • Uses energy • Respond to their environment • Maintains a relatively constant internal environment • Information base in the form of DNA • Composed of One or more cells • Evolved from other living things • Highly organized (Page 9 in Text)

  12. MYSTERY! How did 500 people, in 10 days, get Cholera?

  13. What is Science? Science is based on “knowledge” or “skill” Debate of what science is: Is it mathematical? Who has the knowledge? • Scientist? Laymen? • Does it depend on what the general population believes? • Does science change? How is that knowledge verified? Scientific Method: Francis Bacon (1561-1626) “Baconian Method” PseudoScience

  14. Scientific Method“Baconian Method” • Hypothesis • Prediction and testing • Experimental Design • Rigorous Testing • Duplication Sir Francis Bacon 1561-1626

  15. LabPeriod One: Appropriate Scientific Sources • First Lab Period:  Who determines what is valid scientific results? • What are primary, secondary, and tertiary sources? • How do you read a peer reviewed journal article? • How do you find appropriate sources (library) • Homework:  • Find peer reviewed article and write a summary in electronic journal   • (2-3 sentences)

  16. How do you discern between good and poorly performed science?

  17. Acceptable Resources • Primary • Original source or evidence • Peer reviewed journal articles • Secondary • Cite, comment on, or build upon primary sources • Books, scientific magazines • Tertiary • Compilation of primary and secondary sources

  18. How you do discern acceptable resources? • In a small group check the resources on your desk. • Which are acceptable for scientific research?

  19. The Nature of Science • Ethics in experimentation • Science Changes
