The scientific method is best described as: A. A rigid set of steps that must always be followed in exact order B. A flexible approach to asking and answering questions about the natural world C. A way to prove absolute truths about nature D. A method used only in laboratory settings Correct Answer: B Rationale: The scientific method is a flexible, logical approach to inquiry that involves observation, hypothesis formation, experimentation, and conclusion drawing. It is not rigid, does not prove absolute truths (rather, it supports or refutes hypotheses), and is used in many settings beyond laboratories. DIF: Easy | KEY: Scientific Method | MSC: Remembering | NOT: Chapter 1, Introduction 2. A scientific hypothesis must be: A. Proven true before it can be tested B. Testable and falsifiable C. Based on a mathematical formula D. Supported by a majority of scientists Correct Answer: B Rationale: A scientific hypothesis is a proposed explanation that must be testable and falsifiable—meaning it can be proven false through observation or experimentation. DIF: Easy | KEY: Hypothesis | MSC: Remembering | NOT: Chapter 1, The Nature of Hypotheses 3. Which of the following is a characteristic of a scientific theory? A. It is a guess with little supporting evidence B. It is a well-supported explanation that has been repeatedly tested C. It is the same as a hypothesis D. It cannot be modified once established Correct Answer: B Rationale: A scientific theory is a broad, well-supported explanation for a wide range of phenomena, backed by extensive evidence and repeated testing. It is not a guess, is distinct from a hypothesis, and can be modified as new evidence emerges. DIF: Easy | KEY: Scientific Theory | MSC: Remembering | NOT: Chapter 1, Scientific Theories 4. In a controlled experiment, the control group: A. Is exposed to the variable being tested B. Is not exposed to the variable being tested C. Always receives a placebo D. Is used to prove the hypothesis Correct Answer: B Rationale: The control group serves as a baseline for comparison by not being exposed to the experimental variable (independent variable). This allows researchers to determine whether changes in the experimental group are due to the variable being tested. DIF: Easy | KEY: Controlled Experiments | MSC: Remembering | NOT: Chapter 1, Controlled Experiments 5. Which of the following is an example of a primary source of scientific information? A. A news article summarizing a study B. A textbook chapter on biology C. A peer-reviewed research article D. A blog post about a scientific discovery Correct Answer: C Rationale: Primary sources are original research reports written by the scientists who conducted the work and published in peer-reviewed journals. News articles, textbooks, and blogs are secondary sources that interpret or summarize primary research. DIF: Moderate | KEY: Primary Sources | MSC: Understanding | NOT: Chapter 1, Evaluating Scientific Information
