Knowledge of the physics and chemistry of the planet’s “bones” is essential to a complete understanding of Earth science. Ranging from the Mohs scale and specific gravity to silicates, carbonates, and halides, this video delves deeply into the composition, properties, and classification of rocks and minerals. An element of forensic-type analysis is also brought into play, since any stony formation represents a portion of the planet’s history and local conditions. 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. (23 minutes)

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 c...(more details)
 
Plate Tectonics
View Video Clip
Studies of our planet's crust, or lithosphere, suggest that it's not a single solid layer at all. This video illustrates the process of scientific inquiry by studying the evolution of our understanding of plate tectonics, the dynamics of those ever-s...(more details)
 
Our Planet Earth
View Video Clip
If Earth's entire history could be compressed into a single year, modern humans would've appeared just 23 minutes ago! Use this video to introduce your students to the concept of geological time (also called deep time); relative age dating of rock vi...(more details)
 
Oceans and Seas
