Biochemical Cycles: Recycling Carbon and Nitrogen

The four cycles in Earth's biogeochemical system are covered in this worksheet. Science stars fill in the blanks or define vocabulary terms pertaining to the hydrologic, carbon, nitrogen, and phosphorous cycles. This resource provides a...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

Learners construct a model of the hydrologic cycle, and observe that water is an element of a cycle in the natural environment. They explain how the hydrologic cycle works and why it is important, and compare the hydrologic cycle to...

The majority of this presentation is a collection of diagrams and graphs that back your lecture on biogeochemical cycles. The last few slides define ecosystems and the Gaia hypothesis. You may find these slides valuable, but will...

As the world turns ... so do the carbon and nitrogen cycles! Introduce them both to eager young biologists through an animated video, part of an extensive biology playlist. The narrator explains how each element moves through its...

A woman had a job crushing cans at the recycling plant; it was soda pressing. Video focuses on the ways our environment recycles, including the water cycle, carbon cycle, nitrogen cycle, and the phosphorus cycle. It also describes the...

An online reading and interactive game bring the path of a carbon molecule to life for your earth science explorers! As an assessment, learners can map out or write about their experience in the carbon cycle. Thoroughly written...

Explain the two-step process of photosynthesis to your high school biologists with a focus on the Calvin cycle. Using adorable animation, a video likens the cycle to a tiny, sustainable factory. Even though the enzyme-bird rubisco and...

Expose your class to the steps of the nitrogen cycle with this short clip. Colorful computer imagery and animation explain how nitrogen travels from the atmosphere as a gas into plants and soil, where bacteria convert it into nitrates....
