A runner wants to know if sports drinks improve speed. Write out the independent variable, dependent variable, control group, experimental group, and two constants for this experiment.

In an essay, explain how the scientific method ensures reliable results in experiments. Your answer should: Describe each step of the method (question, research, hypothesis, test, analyze, conclusion). Explain how proper graphing and error analysis strengthen conclusions. Provide a real-world example of how this process applies to everyday problem solving.
