Investigating Plant Macronutrients Using Hydroponics
kit #36R
Do plants only grow in soil? Not always. Sometimes they grow in water. This stimulating and fun kit includes uniquely designed Lab-Aids® transparent plastic culture chambers that allow students to “clearly” view plant growth and development in various nutrient solutions.
The following experiments are included:
♦ Seed germination time comparisons
♦ Plant growth time comparisons
♦ Effects of nutrient deficiency
♦ An understanding of hydroponics
This highly graphic and unique activity can be used individually or in groups at many grade levels. It is an excellent activity for science fairs or projects.
- Observe plants growing in a nutrient solution
- Study and compare seed germination time and plant growth time
- Observe development of roots, stems and leaves
- Study effects of nutrient deficiency
- Use controls in experiments
- Understand hydroponics
