This kit is designed to illustrate the relationships between bacteria, nitrogen fixation, nitrogen cycling and plant nutrient requirements. Your students will learn what farmers have known for some time-the role the bacteria play and how the plants benefit. Students plant grass seeds which they maintain on three different nutrient media and monitor relative growth over a 25-day study period. The results will be dramatic.
Materials supplied for 24 students working in teams of three.
