  1. What is Science?

  2. What is Science? • Science = Latin “to know” Inquiry is at the heart of science. • Inquiry: search for information and explanation Two main processes: • Discovery science • Hypothesis-based science

  3. Discovery Science • Describes nature through observation and analysis of data • Data = recorded observations • Qualitative and quantitative • Inductive reasoning: derive generalizations based on specific observations

  4. Hypothesis-Based Science • Hypothesis: makes predictions that can be tested by recording more observations or experiments • AP Biology: “If … , then … because…” • Results can either support or refute the hypothesis • Not “My hypothesis is correct”

  5. The Myth of the Scientific Method • Published research articles follow the steps of the “textbook” scientific method • Most scientific inquiriesdon’t follow this structured form • Scientists can be working with the wrong hypothesis and have to redirect research • Discovery science - contributes to understanding of nature without using the “scientific method”

  6. Experiments • Hypothesis • Use control and experimental groups • Design: • Independent variable (IV) • Dependent variable (DV) • Control • Constants • # Trials

  7. Hypothesis Explanation to specific question Tested by experiment or continued observation Can be disproven, but not can’t proven to be true Theory Summarizes group of hypothesis supported by repeated testing Broader in scope New hypotheses can be generated from it Supported by massive body of evidence Hypothesis / Theory / Law Scientific Law • Statement of fact • Explains things, but doesn’t describe them • Generally accepted to be true and universal • Basis for scientific method

  8. Science Practices for AP Bio Use representations and models to communicate and solve problems Use mathematics appropriately Pose scientific questions to extend thinking or guide investigations Plan and implement data collection Analyze data and evaluate evidence Work with scientific explanations and theories Connect and relate knowledge across scales and domains
