This chapter explains how scientists think and how they "do" science. It describes how scientific theories develop and how scientists investigate questions to advance scientific knowledge. The chapter also explains how science may be misused and how and why human subjects are protected in scientific research.
- 1.1: Case Study: Why Should You Learn About Science?
- Samantha and Dave are expecting their first child. They are excited for the baby to arrive, but they are nervous as well. Will the baby be healthy?
- 1.2: What Is Science?
- This young man is getting a flu vaccine.
- 1.3: The Nature of Science
- Did you ever wonder why a moose, like the one pictured here, grows large antlers?
- 1.4: Theories in Science
- The man in this sketch is holding his nose to avoid breathing in miasma. Miasma refers to a toxic vapor that people believed for centuries was a cause of many diseases, including cholera and plague.
- 1.5: Scientific Investigations
- If you were walking in the woods and saw this stream, you probably would wonder what made the water turn orange.
- 1.6: Scientific Experiments
- The spots on this girl's tongue are an early sign of vitamin C deficiency, which is also called scurvy.
- 1.7: Nonexperimental Scientific Investigations
- You've probably seen this warning label dozens of times.
- 1.8: Case Study Shot Conclusion and Chapter Summary
- New mother Samantha left her pediatrician’s office still unsure whether to vaccinate baby James. Dr. Rodriguez gave her a list of reputable sources where she could look up information about the safety of vaccines for herself, such as the Centers for Disease Control and Prevention (CDC).
