Final answer:
The correct order of the scientific method steps is Observation, Hypothesis, Experiment, Conclusion, matching the options B, C, A, and D respectively. If the hypothesis is not supported by the experiment, alternative hypotheses should be proposed.
Step-by-step explanation:
The correct order for the steps of the scientific method is as follows:
1. Observation
2. Hypothesis
3. Experiment
4. Conclusion
Matching these steps to the processes (lettered items):
B. Observation - Make observations.
C. Hypothesis - Form a hypothesis.
A. Experiment - Test the hypothesis.
D. Conclusion - Analyze the results and draw a conclusion.
After performing an experiment, if the hypothesis is not supported by the data, scientists will propose alternate hypotheses. This iterative process continues until a reliable conclusion can be drawn.
