Scientists use critical thinking skills throughout the process of research or experimentation. a student notices that their energy level always seems to decrease when they drink soda, but they seem to have more energy when they don’t drink soda. the student decides to conduct an experiment to determine if their soda intake really does have an effect on their energy level. what critical thinking step has the student just completed in the situation described above?
a.
asking a question
b.
evaluating a promotional claim
c.
adjusting a conclusion
d.
determining a logical conclusion

The step that the student just completed in the situation given above is asking a question.

As the student noticed that consumption of soda deceases their energy level, he asked the question to this why does this happens? this was the first step of using critical thinking skills to ask a question first analyze it and then perform and witness some experimental observations and come out with the conclusion.

But in this given example he just completed the first step of asking question. Therefore, the answer is asking a question which is option A.

The scientific method is carried out in several stages:

1. Observation,

2. Determine the problem

2. Data, collect information

3. Hypothesis

4. Experiments

5. Analysis

6. Conclusion

7. Compilation of laws or theories

In the context of the problem, students will experiment to study the effect of

So students issue a question which is why  can affect their  energy, Thus students have made the first 2 steps in the scientific method :

1. Observation of  and  the human's energy level,

2. Determine the problem that will be the basis of student research, namely the influence of the human's energy level.

Indirectly this student has obtained 2 variables to be examined, namely variable and human energy level, which can be changed according to conditions, which are chosen as fixed variables and which ones are independent variables.

So that the next step is collecting data and so on can be done immediately

If we look at other answer choices :

B. Evaluating a promotional claim

This stage is done after the results of the research have been obtained so that students can submit an evaluation of their learning outcomes

C. Adjusting a conclusion

This stage will be obtained after students have completed the analysis of the experimental data

So the most appropriate answer is A.Asking a question
