Why Do Rivers Curve?

Excite scholars to design their own planet in this first of five lessons. The instructional activity starts with a pre-activity assessment, a complete lesson plan that is easy to implement, and a post-activity assessment that would...

Keep within a water budget. Learners find out that less than 2.5% of Earth's water is available to drink—and that there is a fixed amount of water. Scholars read an interesting article comparing the available water to a game of Monopoly...

Climate change isn't just about a warming planet; it will affect humans' health, spread of disease, changes in heat waves and droughts, and changes in storms and wildfires. Participants explore global climate change through discussions...

Due to climate change, by 2030, food prices could increase by 20-30 percent. The narrator explores climate change and focuses on its effects, not on its causes or validity. He discusses the five scariest effects of climate change and...

This "old school" video is of a teacher using a chalkboard (imagine that!), to illustrate how meandering rivers are created, and how they flow. The teacher does a good job of describing how the meandering river bed changes over time due...

Resource links to a video, satellite images, data, and photographs of glaciers provide emerging earth scientists the opportunity to examine how the ice has been retreating over the years. A data table is included for pupils to record...

Can humans protect other species from the effects of climate change? Can animals adapt or evolve fast enough to survive? Check out this video for some surprising answers.

Researchers think they have evidence of a new planet deep in our solar system that is the size of Neptune and orbits the sun far beyond Pluto. The orbit simulator shows the orbits of our well-known planets, as well as Pluto and the comet...
