Four Spheres Explained

Published on February 5, 2023 by

Our lovely planet operates through a combination of four spheres — atmosphere, hydrosphere, biosphere, and geosphere. These spheres are connected in simple and complex ways. Join Haley and her team as they take the students on a guided virtual tour to these spheres, where they will also define the main characteristics of each sphere. 

This video satisfies the 5-ESS2-1 requirement of fifth-grade science proficiency.

Students who demonstrate understanding can:  5-ESS2-1. Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
