Students investigate the properties of visible light and the sequence of colors in the spectrum using light shone through water and prisms. The instructional activity and accompanying slideshow can both be downloaded.

View a global map from NASA's Earth Observatory that shows net radiation from July 2006 to November 2008. Learn about radiation and the balance between incoming and outgoing energy in the atmosphere.

Energy is neither created nor destroyed - and yet the global demand for it continues to increase. But where does energy come from, and where does it go? This video examines the many ways in which energy cycles through our planet, from...

As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to Earth's atmosphere. Topics covered in the overview include structure of the atmosphere, composition of the atmosphere, energy balance of...

This collection of five learning modules looks at issues related to environmental change and sustainability. Topics addressed include changes in the atmosphere, soil, water, and biodiversity, and what can be done to counteract this and...

With this resource, users join investigators in the exploration of humans' use of and dependence on the many energy resources. Learn about new technologies such as carbon capture and sequestration as an alternative to reduce our carbon...

The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other...

Read about regional and local wind systems, including information on changes in atmospheric pressure, thermal energy in the atmosphere, sea and land breezes, mountain and valley breezes, and monsoon winds.

This video segment adapted from First Light explains why the highest peak in the Pacific, Mauna Kea, is an ideal site for astronomical observations. Featured are new telescope technologies that allow astronomers to explore the universe...

Try and meet global energy demands by using alternative energy sources while keeping the carbon levels in the atmosphere down to acceptable levels. Simulator includes a data table available for download for student records.

An explanation of how temperature is affected by the composition of the atmosphere and how energy flows in and out of Earth's atmosphere.

Students analyze the energy consumption of a household appliance and estimate the amount of carbon dioxide it is adding to the atmosphere each year.

Human beings have an enormous impact on the natural environment, and ultimately on each other. The way we chose to house, clothe, shelter, and meet the needs for vital resources such as food, energy, and water, not only affect the...

Use this site to explore real scientific data relating to the atmosphere. With this information you can gather evidence, test theories, and come to conclusions. Click on the data examples to view a full scale version.

The aim of this article is to relate the history of oxygen in the atmosphere to the evolution of photosynthesis, aerobic respiration, mitochondria, and life on earth.

Prairie Public Education Services award winning documentaries on Germans from Russia focus on the rich history of Germans from Russia and their migration to America. Indian Pride, the 13-part cultural magazine, showcases the unique...

Using computational models, students investigate the interaction between greenhouse gases, solar radiation, and the Earth's surface for the impact on climate. They then look at data on atmospheric carbon dioxide to analyze changes in...

A pre-assessment at the beginning of a unit on global atmospheric change. It checks understanding of issues around climate change and the impact it has on the environment and on human health. The lesson and accompanying slideshow can...

Students investigate how solar energy can be harnessed to heat water. The lesson and accompanying PowerPoint can both be downloaded, and the student handout is provided in both English and Spanish.

College-level online course highlighting the fundamentals of ecology. Course topics include coevolution of the biosphere, geosphere, atmosphere, and hydrosphere; photosynthesis and respiration; and the carbon, nitrogen, and water cycles....

Learners learn that fossil fuels release energy when they are burned, and this takes the forms of light, heat, gases, etc. In this lesson they explore combustion with a candle and with sugar. The lesson and accompanying PowerPoint can...
