Understanding Scientific Methodology in Biology: The Path from Observation to Theory

This chapter explores the essential methodology underpinning the science of biology. It highlights the importance of a structured approach to scientific inquiry, starting with observation and the formulation of questions. By using logic and creativity, hypotheses are developed and tested through experiments. The chapter delves into the significance of data collection and analysis, ultimately leading to conclusions and the formation of theories. Key examples illustrate how these principles apply to concepts such as evolution, gravity, relativity, and the nature of life itself.

Presentation Transcript

  1. Chapter 1 review The science of Biology

  2. Scientific Methodology • Why does science need to have a method? • Is there a system to science? • If so…what is it? • Ask a question • It all starts with a simple “Observation” • Seeing something “new” for the first time

  3. Scientific Methodology • Form an idea • Make an inference (logic + common knowledge) • Inference + creative imagination  Hypothesis • Try it out • Play with it… EXPERIMENTS!!!! • Get all the info • DATA!!!! • Were you right? • Make a conclusion

  4. Theories???? • What is a Theory? • “Theoryapplies to a well-tested explanation that unifies a broad range of observations and hypothesis and that enables scientists to make accurate predictions” • collaborate • Examples: • Evolution • gravity • relativity • E=mc2

  5. What is alive?
