Inquiries in Science® Biology Series - Help your students understand hard-to-grasp science concepts. Using a learning cycle of engage, explore, explain, extend, and evaluate, each kit features lab activities designed to actively engage students in learning essential science concepts through guided inquiry. Topics addressed by the kits were organized and selected based on data from numerous sources, including the National Research Council's National Science Education Standards, AAAS's Project 2061 Science Benchmarks, NAEP's Science Framework, and state science education standards from across the US.

The Exploring the Nitrogen Cycle Kit includes: Teacher’s manual with instructions Background information Reproducible student sheets Student questions Extension activities Suggestions for differentiated instruction

A Carolina Exclusive! Students explore the importance of different biotic and abiotic factors involved in the nitrogen cycle. Students care for 3 separate tanks containing fish, plants, and bacteria, monitoring the levels of different nitrogen ions.

After discussing the results, students apply their knowledge by constructing a complete nitrogen cycle that combines the fish, bacteria, and plants into one system.

Kit includes lab supplies (enough for at least 30 students working in groups) plus teacher’s manual. Kit Refill replenishes all perishable materials; price includes shipping and handling.
