The Nitrogen Cycle

We have been continuing to learn about the benefits of microbes in our environment. Last week, our focus was on beneficial microbes in soil. After learning all about the nitrogen cycle in class through our text book, each student drew and watercolored their own image to show what they learned.

The next day, we had a visit from Dr. Frank who taught us even more about the nitrogen cycle, specifically about root nodules on the roots of plants like clovers. We learned that they form a symbiotic relationship with nitrogen-fixing bacteria and make the soil more nutrient-dense. Each student got to examine these types of roots and then got into groups to help create a whole-class collage.
