Hydroponics Experiment

SCIENTIFIC CONCEPTS/PROCESSES

• 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.

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.

Students “clearly” view the plants growing in a nutrient solution. 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 by students in grades 4-12 individually or in groups. It is an excellent activity for science fairs or projects.
