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

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

This is a long-term inquiry activity in which students investigate locations they believe harbor cellulose-digesting microbes, collect samples, isolate them on selective media, and screen them for cellulase activity. These novel microbes may be useful for the production of cellulosic ethanol. In the process they learn about plating techniques, serial dilutions, symbiotic relationships and enzyme specificity. Two methods are provided, one focusing on isolation of pure microbial strains, the other focusing on finding symbiotic communities of microbes.
The companion activity is here:

This is an interactive website that provides descriptive information and data related to ten key climate indicators. These climate indicators and related resources show global patterns and data that are intuitive and compelling teaching tools.

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.

This interactive follows carbon as it moves through various components of the carbon cycle.

This visualization shows the molecular interaction of infrared radiation with various gases in the atmosphere. Focus is on the interaction with C02 molecules and resultant warming of the troposphere.

This demonstration shows how water absorbs more heat than air. The corollary that is made is that the oceans are absorbing a lot of the heat related to climate change. The video tutorial shows an engaging demonstration that teachers can do live in their classrooms as part of a larger lesson/discussion about global warming. The video itself also includes an animation of how greenhouse gases contribute to global warming and concludes by mentioning simple solutions for students.

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 compounds) and seawater are affected differently by increasing carbon dioxide in the air.

An interactive simulation that allows the user to adjust mountain snowfall and temperature to see the glacier grow and shrink in response.
