Pro Tips for Choosing Your Topic

• Focus on the 'Why' not just the 'What': A reflective essay in chemistry should analyze your thought process during an experiment, not just the results.
• Connect the Micro to the Macro: Relate a specific molecular interaction you studied to a larger real-world application or ethical issue.
• Use the Gibbs Reflective Cycle: Structure your essay by describing the event, your feelings, an evaluation, an analysis, a conclusion, and an action plan.
• Identify 'Aha!' Moments: Write about the specific moment a difficult concept like back-titration or stereochemistry finally made sense to you.
• Be Honest About Failure: Some of the best reflective writing comes from analyzing why an experiment failed and what that taught you about the nature of science.
