Dinosaur Pee?: Crash Course Kids #24.2

Today we continue our exploration of the water cycle by drinking some dinosaur pee. Yep! Well, it s a little less gross than it sounds. It turns out that all of the water on Earth is just constantly recycled in what we call a closed system. No water comes in and no water goes out. So that means that, at some point, it s possible the water we re drinking was once dinosaur pee... or tears... This first series is based on 5th-grade science. We re super excited and hope you enjoy Crash Course Kids! ///Standards Used in This Video/// 5-ESS2-1. Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
