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?

The best answer to the question: What critical thinking step has the student just completed in the situation described above, would be: formulated a research question.

Explanation:

The process of initiating research requires a lot of steps, some of which can be pretty complex. However, the beginning of research does not tend to be that difficult. Usually, research initiates from a person observing certain circumstances, or events, around them. These observations lead to ideas that start to attempt to explain the when, why, how, who, or what, of that event, and also the connections that these events may have with others. While the initial step comes from curiosity and observation, the next, and crucial step comes from asking questions. Asking questions help a researcher to begin to narrow a subject of research down and clarify points. It is from the formulation of a research question, that a thesis arises. In this case, we say the student is in this part of the process because he/she has just asked the question of whether taking soda alters their energy levels, or not. They already went through the curiosity part, by observing the event of when they take soda, vs not, in relation ot their energy. Now, they are formulating the question that will lead to research.
