Question 1: What is the very first step of the scientific method?
- Conduct an experiment
- Make an observation
- Form a hypothesis
- Analyze data
Answer: B. Make an observation
Explanation: The scientific method begins with making an observation, where a scientist notices and records a phenomenon using their senses to identify a problem.
Question 2: What is a testable prediction that explains a phenomenon?
- Observation
- Data analysis
- Hypothesis
- Conclusion
Answer: C. Hypothesis
Explanation: A hypothesis is an educated guess or a testable prediction that explains a phenomenon based on prior observations made by the researcher.
Question 3: Which variable does the experimenter change or control?
- Conclusion
- Control group
- Independent variable
- Dependent variable
Answer: C. Independent variable
Explanation: The independent variable is the specific factor that the experimenter intentionally changes or controls during an experiment to test its effect.
Question 4: What is the factor measured to see how it responds to changes?
- Independent variable
- Dependent variable
- Hypothesis
- Control group
Answer: B. Dependent variable
Explanation: The dependent variable is the factor that is measured or observed to see how it responds to changes in the independent variable.
Question 5: What is the purpose of a control group in an experiment?
- To change the results
- To provide a comparison
- To analyze the data
- To replace the hypothesis
Answer: B. To provide a comparison
Explanation: A control group is a part of an experiment that does not receive the experimental treatment and is used as a baseline for comparison.
Question 6: What step involves reviewing results to identify patterns?
- Report conclusions
- Ask a question
- Conduct research
- Analyze data
Answer: D. Analyze data
Explanation: Analyzing data means reviewing the results collected during the experiment to identify patterns, trends, or relationships within the gathered information.
Question 7: What is the final summary of whether a hypothesis is supported?
- Research
- Conclusion
- Experiment
- Observation
Answer: B. Conclusion
Explanation: A conclusion is the final summary that states whether the hypothesis was supported or rejected based on the evidence from the experiment.
Question 8: What is the process of asking questions based on evidence?
- Hypothesis testing
- Observation
- Scientific inquiry
- Data analysis
Answer: C. Scientific inquiry
Explanation: Scientific inquiry is the broad process of asking questions and developing explanations for phenomena based on evidence gathered through investigation.
Question 9: Which step follows 'Make an Observation' in the scientific method?
- Ask a question
- Analyze data
- Conduct an experiment
- Report conclusions
Answer: A. Ask a question
Explanation: After making an observation, the next logical step in the standard seven-step scientific method is to ask a question about that observation.
Question 10: What is the step where you test your hypothesis?
- Report conclusions
- Make an observation
- Conduct an experiment
- Conduct research
Answer: C. Conduct an experiment
Explanation: The experiment step involves testing the hypothesis by changing one variable to see if it causes a measurable change in another variable.
