In this activity, students work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five years and annual variation driven by photosynthesis. This exercise enables students to practice basic quantitative skills and understand how important sampling intervals can be when studying changes over time. A goal is to see how small sample size may give incomplete picture of data.

In this experiment, students investigate the importance of carbon dioxide to the reproductive growth of a marine microalga, Dunalliela sp. (Note that the directions are for teachers and that students protocol sheets will need to be created by teachers.)

In this experiment, students observe a natural process that removes carbon dioxide (CO2) from Earth's atmosphere. This process is a part of the carbon cycle and results in temperature suitable for life. Students learn that the carbon cycle is a fundamental Earth process. Throughout Earth's history, the balance of carbon has kept the atmosphere's carbon dioxide (CO2) and Earth's temperature within relatively narrow ranges.

Interactive visualization that provides a basic overview of the Earth's carbon reservoirs and amount of carbon stored in each, CO2 transport among atmosphere, hydrosphere, geosphere, and biosphere, and a graph comparing global temp (deg C) and atmospheric CO2 levels (ppm) over the past 1000 years.

Step 1. Students are asked to keep track of their energy use from a variety of sources (heating/cooling, electricity, transportation, secondary emissions, etc) during the 9 days of Thanksgiving break, when many of them are likely to travel. They use the total for the 9 days that they calculated using an online calculator to estimate their yearly footprint and compare it to US and world averages. For most of them, the amount of carbon emitted during those 9 days is quite large because of airplane travel or long-distance driving. However, using a week of break when many students will travel allows them to become aware of the significance of transportation in carbon emissions. We provided a table with electricity and heating/cooling bills for various residence halls for students who stay on campus during the break.
Step 2. Students complete an online survey where they are asked to enter the values that they have obtained for the various components of the calculator, perform some simple calculations and compare their annual footprint to the U.S. average. We used SurveyGizmo for the survey because it allows to download the data in a spreadsheet format and has some limited plotting features. The free version allows a maximum of 250 submissions, the Basic version ($19 per month, can be canceled at any time) has unlimited submissions. Step 3. Students write an essay through BlackBoard/WebCT (Assignment). A few guiding questions are provided for this essay where students reflect on the results of their impact on the global carbon budget, what they found surprising, and if they plan to make any changes to their lifestyle to limit their impact. No length limit is set for the essay.
The guidelines and components of this assignment are available on a wiki page. The three steps can be implemented in BlackBoard/WebCT as a Lesson Plan with links to the online calculator (step 1), to the survey (step 2), and to the Assignment/essay (step 3).

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 trees. They determine the species of trees in the set, measure trunk diameter at a particular height, and use the spreadsheet to calculate carbon content of the tree using forestry research data.

In this media-rich lesson, students explore careers in science through profiles of Alaska Native scientists. They consider how traditional ways of knowing and Western approaches to science can complement each other and allow students to incorporate their own interests when considering careers in science.

Compiled and modified for instructional use by: Kate Darby, Western Washington University In 1887, Robert Towne built a metals smelter two and a half miles northwest of El Paso, Texas, across the river from Ciudad Juarez in Mexico and across the state border from several small towns in New Mexico. The smelter, which processed metal ore from regional mines, was quickly acquired by ASARCO (American Smelting and Refining Company) and became an important visual and economic institution in the region. In 1967, following the mantra of environmental regulation at the time—"the solution to pollution is dilution"—ASARCO erected what was then the tallest smokestack in the world: an 828-foot structure visible from much of the region. While the facility provided jobs to many in the region and produced metals important for a range of manufacturing and consumer products, by the 1970s, residents and scientists began to question the other products from the smelter—especially heavy metals pollution.

The Air Quality Management District officials in the Los Angeles region were initially at a loss to determine the odor's source. Investigators from Ventura to Palm Springs looked for toxic spills, sewage plant leaks, and gas line breaks—all for naught.
The smell's origin was the Salton Sea more than 150 miles away and not usually upwind. The smell of an algal bloom and subsequent massive fish kill released odor molecules redolent with the stench of environmental decay.

This case study is an examination of the chemical and sensory impacts of a variety of environmental issues including sand mining, leaking underground gasoline storage tanks (LUSTs), and a railroad.
Wedron is a small, unincorporated town of approximately 100 residents in north central Illinois. A large sand mine has been in operation on the south and west sides of the town for many decades, and the mine property includes several abandoned and active pits, a processing plant, and a train car loading facility. Railroad tracks are located along the east side of town as is a grain elevator (storage and loading facility).
The following information was obtained from the US EPA web site about Wedron, personal visits to the town, and published news articles.

I designed this activity as a role-playing game to help students understand both the concept of climate modeling and how the climate system works. Students take on the role of a climate system component, examining their personal reactions to climate stimuli and building a future scenario based on their group's reactions. You can implement this teaching collection as part of the Climate of Change InTeGrate Module, Unit 5, or as a stand-alone activity.
