Forest fires, brush fires, and slash and burn agriculture are a significant force for environmental change. Remote sensing of fires, smoke and burn scars allows for improved detection of fire characteristics as well as their short- and long-term effects on ecosystems. This site from NASA's Earth Observatory discusses the importance of fires, trace gases emissions, aerosol emissions, and NASA and NOAA missions for monitoring global fires. Case studies and data sets are also available.
This lesson examines the effects of surface energy transfer and storage on ocean temperatures. Included are activities that introduce the use of scientific models. Students then use an energy flow computer model to track energy changes by manipulating four variables: solar energy, heat transfer, water transparency, and seasons of the year. Note that this is lesson four of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently. See Related URL's for links to the Ocean Motion Website that provide science background information, data resources, teacher material, student guides and a lesson matrix.

Topics include greenhouse gas emissions, the possible consequences of global warming, and debates among proponents and opponents about whether global warming is indeed happening and whether it represents a danger to the planet.
This self-paced tutorial investigates evidence for contemporary climate change by examining multi-year weather, statistical and anecdotal records obtained from several U.S. localities. Learners plot and identify trends in regional weather data, learn the difference between weather and climate, and explore the pedagogic advantages associated with learning about global climate change by examining regional data. Videos describing local phenological data of changing seasonality, data portals, an interview with NASA scientist, Dr. Eric Fetzer, and activities to adapt for middle and high school classrooms are included. Vocabulary are linked to a glossary. This is the third of ten professional development modules providing opportunities for teachers to learn about climate change through first-hand data exploration.
Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!
Water travels... a lot. In fact, the water cycle is amazing and takes water all over the planet by using evaporation, condensation, and precipitation. In this episode of Crash Course Kids, Sabrina shows us how the water cycle works and how you can create a mini water cycle right in your own kitchen!
How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?
What happens to a single ecosystem when the amount of freshwater available in it changes? Not really much good. In this episode of Crash Course Kids, Sabrina talks about ecosystems and how one small change can lead to a cascade effect in the entire ecosystem.
