Planet Earth is an amazing machine, and we—and our future—are riding on it. This video introduces students to the Earth system’s primary interacting subsystems (the biosphere, geosphere, hydrosphere, and atmosphere); the nitrogen, carbon, and water cycles; and three surface processes: weathering, mass-wasting, and erosion. The greenhouse effect, the impact of acid rain on the environment, and diminishing freshwater resources around the world are considered as well. A viewable/printable instructor’s guide is available online. Correlates to National Science Education Standards, National Educational Technology Standards, and Standards for the English Language Arts. A Cambridge Educational Production. (19 minutes)
