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?

This NASA animation depicts thermohaline circulation in the ocean and how it relates to salinity and water density. It illustrates the sinking of water in the cold, dense ocean near Iceland and Greenland. The surface of the ocean then fades away and the animation pulls back to show the global thermohaline circulation system.

In this video, the mountain pine beetle problem is explained by two scientist. Their research investigates the beetle and how climate change is impacting its spread.

In this short video from ClimateCentral, host Jessica Harrop explains what evidence scientists have for claiming that recent global warming is caused by humans and is not just part of a natural cycle.

This video is one of a series from the Switch Energy project. It presents pros and cons of hydraulic fracturing, or fracking. In this video, new fracking technologies are presented as more economical and environmentally safe.

This visualization is a map showing the global Climate Demography Vulnerability Index (CDVI) - areas of human population with the highest vulnerability to the impacts of climate change.

This activity introduces students to the process of converting sunlight into electricity through the use of photovoltaics (solar cells). Students complete a reading passage with questions and an inquiry lab using small photovoltaic cells.

This NBC Learn video features climate scientists doing their research on Mt. Kilimanjaro to study the climate of the past. The scientists put the recently observed changes on the glacier into perspective by comparing past climate fluctuations, stressing that the current observed rate of change is unprecedented.

Students will use real satellite data to determine 1) where the greatest concentrations of aerosols are located during the course of a year in the tropical Atlantic region and 2) their source of origin. This is an inquiry-style lesson where students pull real aerosol data and attempt to identify trends among data sets.

This Flash animation describes how hybrid-electric vehicles (HEVs) combine the benefits of gasoline engines and electric motors and can be configured to obtain different objectives, such as improved fuel economy, increased power, or additional auxiliary power for electronic devices and power tools.
