The Global Carbon Budget 1960 - 2100

This simulation allows the user to project CO2 sources and sinks by adjusting the points on a graph and then running the simulation to see projections for the impact on atmospheric CO2 and global ...

Comparison of the Effects of Increased CO2 in the Air to Seawater and Distilled Water

This well-designed experiment compares CO2 impacts on salt water and fresh water. In a short demonstration, students examine how distilled water (i.e., pure water without any dissolved ions or ...

Carbon Sequestration in Campus Trees

In this activity, students use a spreadsheet to calculate the net carbon sequestration in a set of trees; they will utilize an allometric approach based upon parameters measured on the individual ...

Using the Carbon Cycle Interactive Game in the Classroom

In this activity, students learn how carbon cycles through the Earth system by playing an online game.

Carbon Dioxide - Sources and Sinks

In this lab activity, students use a chemical indicator (bromothymol blue) to detect the presence of carbon dioxide in animal and plant respiration and in the burning of fossil fuels and its absence ...

Sediments and the Global Carbon Cycle

A series of activities designed to introduce students to the role of sediments and sedimentary rocks in the global carbon cycle and the use of stable carbon isotopes to reconstruct ancient ...

How does Temperature Affect the Solubility of CO2 in Water?

This short investigation from Carbo Europe explores how temperature relates to the solubility of carbon dioxide in water.

Frozen Carbon

This is a polar map of permafrost extent in the Northern Hemisphere. A sidebar explains how permafrost, as it forms and later thaws, serves as both a sink and source for carbon to the atmosphere. ...

Getting carbon into the ocean is one matter. Getting it down to the depths is another.

This interactive shows the different components of the ocean biological pump, i.e., how carbon in the form of either plankton or particles moves into the ocean's depths. It illustrates the situation ...

The Carbon Cycle

This narrated slide presentation shows the carbon cycle, looking at various parts of this biogeochemical sequence by examining carbon reservoirs and how carbon is exchanged among them and the ...
