Is it really that big of a deal if the global climate undergoes a little change? Young environmentalists consider this very question as they discuss in small groups the impact of different climate change scenarios on their lives, their...

With the global temperature on the rise, the effects of climate change are starting to be seen. However, many people have a difficult time conceptualizing the long-term effects, such as sea levels rising. Given an easy and effective...

What can conductivity tell us about a glacier? Groups analyze glacial melt to determine salt content through an analysis of the pH and conductivity measurements of two samples. Groups then determine the source of the salts. 

Sixth graders explore the damage associated with an earthquake by designing a structure that can withstand earthquake intensities on a shaker board. They then view tips for preparing for an earthquake, and what to do after an earthquake...

Young geologists piece together the puzzle of plate tectonics in an earth science lesson. Given a physical map of the world, they search for land formations that indicate the location of different types of plate boundaries.

How is the Earth like an onion? In this video from PBS Digital Studios, viewers first learn the different layers of Earth and their properties. In addition, they hear how these layers came about, starting with the Big Bang theory and the...
