* Observation: The student is starting with a question about the health of mice.

* Hypothesis: They will likely form a hypothesis about which foods are healthiest (e.g., "Mice that eat more fruits and vegetables will be healthier than mice that eat mostly processed food").

* Experimentation: The student would design and conduct an experiment to test their hypothesis. This might involve feeding different groups of mice different diets and then measuring their health outcomes.

* Analysis: The student would analyze the data from their experiment to see if it supports their hypothesis.

* Conclusion: Based on the results, the student would draw a conclusion about the healthiest foods for mice.

Key elements of science are present:

* Empirical evidence: The student is looking for evidence from experiments to support their claims.

* Testable hypothesis: The hypothesis can be tested through experiments.

* Objectivity: The student aims to gather objective data, free from bias.

Of course, this is a simplified example. A proper scientific study would be more complex and involve controls, repetition, and peer review.
