In this activity, students use datasets from both the Northern and Southern hemispheres to observe seasonal and hemispheric differences in changes to atmospheric C02 release and uptake over time.

This activity relates water temperature to fishery health within inland freshwater watersheds as a way to explore how environmental factors of an ecosystem affect the organisms that use those ecosystems as important habitat.

This is a multi-step activity that helps students measure, investigate, and understand the increase in atmospheric CO2 and the utility of carbon offsets. It also enables students to understand that carbon offsets, through reforestation, are not sufficient to balance increases in atmospheric C02 concentration.

Students explore their own Ecological Footprint in the context of how many Earths it would take if everyone used the same amount of resources they did. They compare this to the Ecological Footprint of individuals in other parts of the world and to the Ecological footprint of a family member when they were the student's age.

In this Webquest activity, students assume roles of scientist, business leader, or policy maker. The students then collaborate as part of a climate action team and learn how society and the environment might be impacted by global warming. They explore the decision making process regarding issues of climate change, energy use, and available policy options. Student teams investigate how and why climate is changing and how humans may have contributed to these changes. Upon completion of their individual tasks, student teams present their findings and make recommendations that address the situation.

This series of activities introduces students to the technologies of batteries and fuel cells. Activities include a mix of lectures, demonstrations, and lab activities.

In this activity, students conduct an energy audit to determine how much carbon dioxide their family is releasing into the atmosphere and then make recommendations for minimizing their family's carbon footprint.

In this activity, students explore the basic living requirements of algae (phytoplankton)through hands-on experience and an interactive game. Students investigate what algal biofuels are, how they are made, where they can grow, and, most importantly, why this topic should be investigated. Algal biofuels are an emerging source of renewable energy.

In this hands-on activity, students examine how the orientation of a photovoltaic (PV) panel -- relative to the position of the sun -- affects the energy-efficiency of the panel.

In this activity, student teams research and develop a proposal to decrease the carbon footprint of their city's/town's public transportation system and then prepare a report that explains why their transportation plan is the best for their community.
