Do plants only grow in soil? Not always. Sometimes they grow in water. This Lab-Aid incorporates a uniquely designed LAB-AIDS‚® transparent plastic culture chamber making the study of hydroponics stimulating and fun. Studentsclearly view the plants growing in a nutrient solution. This highly graphic and unique activity can be used by students in grades 4-12 individually or in groups. It is an excellent activity for science fairs or projects.
The following experiments are included:
Seed germination time comparisons‚
Plant growth time comparisons‚
Effects of nutrient deficiency‚
An understanding of hydroponics‚
‚
Scientific Concepts:
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
