This activity illustrates the carbon cycle using an age-appropriate hook, and it includes thorough discussion and hands-on experimentation. Students learn about the geological (ancient) carbon cycle; they investigate the role of dinosaurs in the carbon cycle, and the eventual storage of carbon in the form of chalk. Students discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth. Finally, they may extend their knowledge to the concept of global warming and how engineers are working to understand the carbon cycle and reduce harmful carbon dioxide emissions.

This activity introduces students to different forms of energy, energy transformations, energy storage, and the flow of energy through systems. Students learn that most energy can be traced back to nuclear fusion on the sun.

This video is part two of a seven-part National Academies series, Climate Change: Lines of Evidence. The video outlines, with the use of recent research and historical data, how we know that the Earth is warming.

This is a real-time map of current drought conditions in the US, which can be zoomed to the state level, with access to many more resources at that level. Some of these include the National Drought Regional Summaries and animations of historical data.

This music video features a rap song about some of the causes and effects of climate change with the goal of increasing awareness of climate change and how it will impact nature and humans.

This small-group activity uses engineering concepts to design energy systems for three off-the-grid towns in Mali, Ethiopia, and Namibia.

This short video illustrates the phenomena of El Niño and La Niña: their relationships to tradewinds and surface water temperatures, and their effects on precipitation in North America.

This is a hands-on activity students design, build, and test. They compare the energy-generating capacities of vertical- and horizontal- axis wind turbine prototypes they have built as potential sources for power in a home.

In this activity, students work through the process of evaluating the feasibility of photovoltaic solar power in 4 different US cities.

In this activity, students explore real data about renewable energy potential in their state using a mapping tool developed by NREL (National Renewable Energy Laboratory) to investigate the best locations for wind energy, solar energy, hydropower, geothermal energy, and biomass.
