BSC 101 Exam 1 Questions and Answers
Solved 100% Correct!!
1. What is the correct order of the scientific method myth?
A. Question, Observe, Experiment, Evaluate, Conclude
B. Observe, Question, Experiment, Evaluate, Conclude
C. Experiment, Observe, Question, Evaluate, Conclude
D. Observe, Experiment, Question, Conclude, Evaluate
Correct Answer: B. Observe, Question, Experiment, Evaluate,
Conclude
Explanation: The traditional myth follows a linear sequence:
Observation leads to a Question, which leads to an Experiment,
followed by Evaluation and Conclusion.
2. Which of the following is a criticism of the scientific method
myth?
A. It is too complex for students
B. It ignores the role of creativity and imagination
C. It requires too much technology
D. It is not used by real scientists
Correct Answer: B. It ignores the role of creativity and imagination
Explanation: The myth is criticized for being oversimplified and
ignoring the creative, non-linear, and social aspects of real science.
,3. In the scientific method, what is a hypothesis?
A. A broad explanation for a wide range of phenomena
B. A proposed explanation for a narrow set of phenomena
C. A statement of fact based on observation
D. A guess that cannot be tested
Correct Answer: B. A proposed explanation for a narrow set of
phenomena
Explanation: A hypothesis is a specific, testable explanation for a
narrow set of observations.
4. What is the primary difference between a hypothesis and a
theory?
A. A hypothesis is proven, a theory is not
B. A theory is broader and supported by more evidence
C. A hypothesis is only used in physics
D. A theory is just a guess
Correct Answer: B. A theory is broader and supported by more
evidence
Explanation: A theory is a broad explanation supported by many lines
of evidence, while a hypothesis is narrow and specific.
5. Which of the following is an example of a scientific theory?
A. The law of gravity
B. Evolution by natural selection
C. The hypothesis that plants need water
D. The observation that the sky is blue
,Correct Answer: B. Evolution by natural selection
Explanation: Evolution by natural selection is a broad scientific
theory supported by extensive evidence.
6. What is a scientific law?
A. A statement based on repeated experimental observations
B. A guess about the natural world
C. A broad explanation for a wide range of phenomena
D. A hypothesis that has been proven
Correct Answer: A. A statement based on repeated experimental
observations
Explanation: A law describes a phenomenon of nature, often
mathematically, based on repeated observations.
7. Which of the following is a key role of the scientific community?
A. To prove theories are correct
B. To act as critics and fact-checkers
C. To prevent new ideas from being published
D. To keep science secret
Correct Answer: B. To act as critics and fact-checkers
Explanation: The scientific community critiques and fact-checks new
ideas before publication to ensure accuracy.
8. What does it mean that science is iterative?
A. It is a linear process
B. It is a circular process that always circles back to the same question
C. It is a one-time event
, D. It is a random process
Correct Answer: B. It is a circular process that always circles back
to the same question
Explanation: Science is iterative, meaning it involves cycles of
testing and refinement that often return to the original question.
9. In the scientific method, what is a prediction?
A. A guess about the outcome of an experiment
B. A statement of what you expect to observe if the hypothesis is true
C. A conclusion drawn from data
D. A broad explanation of nature
Correct Answer: B. A statement of what you expect to observe if the
hypothesis is true
Explanation: A prediction is a testable statement about what should
happen if the hypothesis is correct.
10. What is the independent variable in an experiment?
A. The variable that is measured
B. The variable that is manipulated
C. The variable that stays the same
D. The variable that is random
Correct Answer: B. The variable that is manipulated
Explanation: The independent variable is the factor that the
researcher changes or manipulates.
11. What is the dependent variable in an experiment?
A. The variable that is manipulated
