In this video segment, the ZOOM cast demonstrates how to use cabbage juice to find out if a solution is an acid or a base.

In this audio slideshow, an ecologist from the University of Florida describes the radiocarbon dating technique that scientists use to determine the amount of carbon within the permafrost of the Arctic tundra. Understanding the rate of carbon released as permafrost thaws is necessary to understand how this positive feedback mechanism is contributing to climate change that may further increase global surface temperatures.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.

Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

By the end of this section, you will be able to:Identify the macronutrients needed by prokaryotes, and explain their importanceDescribe the ways in which prokaryotes get energy and carbon for life processesDescribe the roles of prokaryotes in the carbon and nitrogen cycles

By the end of this section, you will be able to:Discuss the biogeochemical cycles of water, carbon, nitrogen, phosphorus, and sulfurExplain how human activities have impacted these cycles and the potential consequences for Earth

By studying key processes in the carbon cycle, such as photosynthesis, composting and anaerobic digestion, students learn how nature and engineers "biorecycle" carbon. Students are exposed to examples of how microbes play many roles in various systems to recycle organic materials and also learn how the carbon cycle can be used to make or release energy.

In this activity, students conduct a short hands-on demonstration that simulates ocean acidification resulting from excess atmospheric carbon dioxide and discuss potential implications of increases in ocean temperatures and acidification due to climate change.

This video is narrated by climate scientist Richard Alley. It examines studies US Air Force conducted over 50 years ago on the warming effects of CO2 in the atmosphere and how that could impact missile warfare. The video then focuses on the Franz Josef glacier in New Zealand; the glacier is used to demonstrate a glacier's formation, depth of snow fall in the past, and understand atmospheric gases and composition during the last Ice Age. Supplemental resources are available through the website.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"In terrestrial and freshwater ecosystems, fungi are essential for nutrient cycling, releasing carbon dioxide into the atmosphere and inorganic nitrogen and phosphorus into the soil. In contrast, in marine environments, fungi are often considered to be associated with debris and less essential to the element cycle than other microbes such as prokaryotes and phytoplankton. A recent study sought to better understand the role of open-sea, or pelagic, fungi in carbon cycling in the ocean. Using multi-omics techniques and existing genomic datasets, researchers performed a global analysis of carbohydrate-active enzymes (CAZymes) – key enzymes in carbon cycling – in ocean fungi. They found that pelagic fungi are active in carbohydrate degradation, as indicated by a high ratio of CAZyme transcripts..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Students will explore the cycling of carbon between the atmosphere, geosphere, biosphere, and hydrosphere through both naturally occuring and human caused effects. Students will also explore how the ocean, an important carbon sink, is impacted by the rise of CO2 levels due to human activities and how life in the oceans is impacted as a result through a series of short video experiments.

This lesson was originally created to give elementary school teachers a foundation for understanding the impacts of climate change. Teachers, acting as students, physically participate in the movement of carbon throughout various biospheres.

This activity from NOAA Earth System Research Laboratory introduces students to the scientific understanding of the greenhouse effect and the carbon cycle. The activity leads them through several interactive tasks to investigate recent trends in atmospheric carbon dioxide. Students analyze scientific data and use scientific reasoning to determine the causes responsible for these recent trends. By studying carbon cycle science in a visual and interactive manner, students can learn firsthand about the reasons behind our changing climate.

This interactive animation focuses on the carbon cycle and includes embedded videos and captioned images to provide greater clarification and detail of the cycle than would be available by a single static visual alone.

The carbon cycle game is a short digital game that helps you teach how carbon atoms move through various forms including soils, the ocean, plant and animal life and fossil fuels. Actions such as photosynthesis, plant and animal death and forest fires all convert carbon from one form into another. This is a card style game. It allows for single or multi players. Runs on a browser.

In this activity, students develop concept maps of the carbon cycle through a die-rolling game that simulates carbon reservoirs and fluxes. By the end of this activity, students should be able to describe and explain how the carbon cycle has changed in the last 250 years.
