In this module, students will learn about the cycles of nature (water, carbon, nitrogen, and phosphorus) that support the flow of nutrient matter through an ecosystem, as distinct from the flow of energy. Includes learning activities, a study guide, flashcards, and quizzes.

This pathway explores the importance of biodiversity and human impact on the environment.
This tutorial looks at carbon dioxide in the atmosphere and how changes can impact wheat production in Kansas.
Students examine the importance of carbon and learn about two Earth systems, the solubility pump and the biological pump, which cycle carbon from the atmosphere into the oceans and back again.
Students learn about energy and nutrient flow in various biosphere climates and environments. They learn about herbivores, carnivores, omnivores, food chains and food webs, seeing the interdependence between producers, consumers and decomposers. Students are introduced to the roles of the hydrologic (water), carbon, and nitrogen cycles in sustaining the worlds' ecosystems so living organisms survive. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
In a multi-week experiment, student groups gather data from the photobioreactors that they build to investigate growth conditions that make algae thrive best. Using plastic soda bottles, pond water and fish tank aerators, they vary the amount of carbon dioxide (or nutrients or sunlight, as an extension) available to the microalgae. They compare growth in aerated vs. non-aerated conditions. They measure growth by comparing the color of their algae cultures in the bottles to a color indicator scale. Then they graph and analyze the collected data to see which had the fastest growth. Students learn how plants biorecycle carbon dioxide into organic carbon (part of the carbon cycle) and how engineers apply their understanding of this process to maximize biofuel production.
This resource provides information on all of the aspects of global warming, climate change, and the future of the earth.

Carbon is one of the most common elements found in living organisms. Chains of carbon molecules form the backbones of many molecules, such as carbohydrates, proteins, and lipids. Carbon is constantly cycling between living organisms and the atmosphere. The cycling of carbon occurs through the carbon cycle. Learn more about the carbon cycle in this learning module produced by CK-12.

The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to become acidic. What impact does that have on the marine life? In this ocean science fair project, you will demonstrate ocean acidification and investigate the effect on the shells of marine life.
Video talks about the carbon cycle and uses a computer as a metaphor to show how the cycle can be disrupted by climate change. [3:55] Includes a short quiz and a list of additional resources to explore.
Page describes Photosynthesis in great detail. Provides an extensive amount of links on all different aspects of photosynthesis. Very thourough.
