To conclude their examination of forest ecosystems, class members consider the role forests play in the carbon cycle and how forests can offset climate change.

The reintroduction of a species to an area doesn't always go as expected. Scholars learn about the reintroduction of wolves into Yellowstone National Park with a video, reading, and discussion questions. They complete a hands-on activity...

Class members explore the carbon cycle in the final installment of the 10-part Discover Your Changing World series. They play a simulation game where they walk through the steps carbon takes as it cycles through the different layers...

For this complex game about the carbon cycle, the playing field is divided into air, living, and earth zones. Children are assigned to be either plants or animals, and collect carbon tokens as they proceed from zone to zone. While the...

In this activity, you'll describe what you think it might be like for humans to live in the extremes of the biosphere. Think about the challenges associated with living either underwater or in the upper atmosphere. Also, think about what...

A lab experiment in a series of experiments that explores Earth Science Systems. This lab introduces students to the parts of the Earth system: the atmosphere, hydrosphere, biosphere, and pedosphere. As the students learn about the...

[Free Registration/Login Required] In this interactive you will need to organize the labels according to where they belong in the biosphere. You will need a sign-in to access this media, but it will be well worth your time!

Students learn about population density within environments and ecosystems. They determine the density of a population and think about why population density and distribution information is useful to engineers for city planning and...

Investigate the scientific principles of biospheres, and observe the effects of biological processes on closed systems.

Using a surficial features map, students see the connections between those features and other Earth systems. They will consider the interactions of the geosphere, hydrosphere, biosphere, and atmosphere.

In this activity, you will identify a problem affecting the world at large, and then predict a vision of the future based on this problem and what you now know about the history of the Universe.

Natural Disasters are typically the result of a variety of factors, which begs the question, are these natural disasters really natural, or are they a result of something man-made? This activity is designed to get you to think about the...

The claim tester gang comes face-to-face with Orx-30. This comic focuses around the topic of sustainable forms of energy.
