About

If we had to pick a VIP of the air you breathe, we might just pick nitrogen! (What, you were expecting oxygen?) In this BrainPOP movie, Tim and Moby take you on a tour of the nitrogen cycle. Learn why the most abundant element in our atmosphere is so important to life on Earth. Explore how gaseous nitrogen is transformed into proteins that can be used by plants, animals, people, and even bacteria! Follow a nitrogen molecule from the air above us to the soil below us to the roots of plants and back again. And discover the roles played by bacteria every step of the way. You’ll never look at your lunch the same way again!
