Frequently Asked Questions
Can I do chemistry research at home? Yes, with appropriate precautions. Focus on food chemistry, natural products, environmental testing, and other safer areas. Avoid concentrated chemicals, organic solvents, and hazardous reactions.
What safety equipment do I need? At minimum: safety goggles, appropriate gloves, and a work area away from food. For more advanced work: lab coat, fume hood access, and proper chemical storage.
How do I get access to a university lab? Contact professors whose research interests you. Be specific about your project idea, demonstrate chemistry knowledge, and be persistent. Many labs welcome motivated high school students.
What's the difference between chemistry and biochemistry at science fairs? Chemistry focuses on chemical reactions and properties. Biochemistry involves chemistry of living systems. Projects involving enzymes, metabolism, or biological molecules often fit better in biochemistry.
Do I need to memorize reactions for research? Not memorize, but understand. Know common reaction types, how to look up reactions, and the principles behind them. Good laboratory notebooks and references are essential.
