This video is a segment from the Switch Energy Project focusing on energy security. Switch Energy Project is a multi-pronged effort designed to build a balanced national understanding of energy.

This is a debate-style learning activity in which student teams learn about energy sources and are then assigned to represent the different energy sources. Working cooperatively, students develop arguments on the pros and cons of their source over the others.

This interactive contains four animated slides that introduce the greenhouse effect. An additional animation offers to 'explore more'.

This video segment explores whether, in principle, renewable energy resources could meet today's global energy needs of about 15.7 terawatts.

In this activity, students examine climate variability in the North Atlantic associated with the North Atlantic Oscillation (NOA) in a case study format.

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 collection of five short videos that show how climate change is affecting fishing, native populations and access for the oil and gas industry in the Arctic. The videos include personal reflections by writers Andrew C. Revkin and Simon Romero, scientists, and residents about their experience of the impacts of the climate change in the Arctic.

This 15-panel interactive from NOVA Online describes some of the factors (such as Earth's rotation and the sun's uneven heating of Earth's surface) contributing to the formation of the high-speed eastward flows of the jet streams, found near the top of the troposphere. These jet streams play a major role in guiding weather systems.

This activity features video segments from a 2007 PBS program on solar energy. Students follow a seven-step invention process to design, build, and test a solar cooker that will pasteurize water. In addition, they are asked to describe how transmission, absorption, and reflection are used in a solar cooker to heat water and to evaluate what variables contribute to a successful cooker.

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.
