Science Project: Vitamins and Plant Growth

11-year-old Tiffany needs information for a 6th grade science project on "what type of vitamins affect plant growth."

Research Starting Points

Search Google for "vitamins for plant growth" — numerous articles available. Key points:

• Plants synthesize their own vitamins; they don't require dietary vitamins like animals.
• Some experiments test vitamin supplements (B1, C, etc.) on cuttings or seedlings.
• Results are typically minimal or negligible compared to proper light, water, nutrients.
• Focus on macronutrients (N-P-K) and micronutrients (iron, magnesium, etc.)—these are essential.

Project Suggestion

Compare: control (water only) vs. vitamin supplements vs. proper fertilizer. Document germination rates, growth speed, leaf color. This teaches experimental design and plant nutrition basics.

Good luck with the project!
