K-2: Modeling in K-2 builds on prior experiences and progresses to include using and developing models (i.e., diagrams, drawing, physical replica, diorama, dramatization, storyboard) that represent concrete events or design solutions.

An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the Atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources.

Drought conditions have affected much of the U.S. Southwest and Central Plains in recent years. But scientists now believe future droughts in the last half of this century could be the worst in the past millennium.

Fire is a powerful force on our planet. From South America's rainforests to Africa's savannas and Australia's highlands, fires touch 30 percent of the land surface. Yet whether naturally occurring or set by humans, fires' effects reach far beyond ravaged lands.

Model analyst develops models to help visualize, observe, and predict complicated data. Model analysis is the process of taking large amounts of data and separate it into a structure that makes it intelligible to the binary process of computers.

Use the My NASA Data Cubes to guide students’ exploration of data to enrich their observations and inferences.  This is a flexible resource that may be used with a variety of graphical representations of data.  This activity requires a graph for students to evaluate.   For the purposes
