Final answer:
Option D is correct option. The step not included in the scientific method is Memorization. The steps consist of observation, hypothesis formulation, experimentation, and analysis. Memorization is useful for learning facts but does not involve the investigative process of the scientific method.
Step-by-step explanation:
The step in the scientific method that is not common practice is Memorization (Option D). The scientific method is a systematic and logical approach to discovering how things in the universe work. It has several distinct steps, which include the following:
- Observation: The initial step wherein a question is posed or a detail about the natural world is noticed.
- Forming a Hypothesis: After an observation, a hypothesis, which is a proposed and testable explanation for an event, is formulated. The hypothesis should be based on scientific knowledge and must be falsifiable.
- Experimentation: Conducting an experiment to test the hypothesis. This involves gathering data to either support or refute the hypothesis.
- Analysis: Reviewing the data and results of the experiment to determine whether they support the hypothesis.
These steps highlight the process of inquiry that characterizes scientific investigation. If experimental data do not support the hypothesis, a new hypothesis can be proposed and tested through repeatable experiments.
Memorization, while it could be useful for learning established scientific facts, is not a part of the investigative process that defines the scientific method. Therefore, the correct option in the final answer is Memorization.
