This video segment features subsistence fishing and harvesting in the Northwest US. Segment was adapted from a student video produced at Northwest Indian College in Bellingham, Washington.

This video provides an overview of the Center for Transportation Technologies and Systems and its research on alternative fuel vehicles and why they have less impact than current fossil fuel-burning cars on the environment.

In this activity, students are guided through the process of locating and graphing web-based environmental data that has been collected by GLOBE Program participants using actual data collected by students in Pennsylvania and comparing them to their local climatic boundary conditions. This activity highlights the opportunities for using GLOBE data to introduce basic concepts of Earth system science.

In this hands-on activity, students explore whether rooftop gardens are a viable option for combating the urban heat island effect. Guiding question is: Can rooftop gardens reduce the temperature inside and outside houses?

In this activity, students model circulation in gyres, explore characteristics of gyres found around the world, and predict the climate impacts of changes to the circulation in these gyres and climate on adjacent land. Gyres, large systems of rotating ocean currents, play an important role in Earth's climate system.

This static graph of changes in CO2 concentrations is going back 400,000 years, showing the dramatic spike in recent years.

This is a classroom activity about the forcing mechanisms for the most recent cold period: the Little Ice Age (1350-1850). Students receive data about tree ring records, solar activity, and volcanic eruptions during this time period. By comparing and contrasting time intervals when tree growth was at a minimum, solar activity was low, and major volcanic eruptions occurred, they draw conclusions about possible natural causes of climate change and identify factors that may indicate climate change.

This video is one of a series produced by the Switch Energy project. It reviews the pros and cons of natural gas as a source of energy.

This carbon calculator, developed by the EPA, guides students in calculating their carbon footprint and then using that information to make decisions about how to reduce their carbon emissions.

Video introduces wind energy research at the National Renewable Energy Lab (NREL) and provides an overview of the NREL Wind Technology Center near Boulder, Colorado.
