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 Kit Refill replenishes all perishable materials; price includes shipping and handling.

Grades 9–12. Students explore different biotic and abiotic factors of the nitrogen cycle. Students care for 3 separate tanks containing fish, plants, and bacteria, monitoring the levels of different nitrogen ions. Students apply knowledge by constructing a complete nitrogen cycle that combines the fish, bacteria, and plants into one system.

• Create a working nitrogen cycle using living organisms
• Investigate environmental connections between fish, nitrifying bacteria, and plants
• Identify sources for nitrate, nitrogen dioxide, and ammonia in aquatic systems

Note: Order the Kit Refill with the perishable materials included or with a prepaid coupon to request the perishables later at your convenience. Contact us or return the coupon at least 2 weeks prior to requested delivery date to ensure prompt arrival of materials.
