In this activity, students explore three indicators of drought are: soil moisture, lack of precipitation, and decreased streamflows. Students investigate each of these parameters develop a sense for the effects of drought on land.  

NASA visualizers take data – numbers, codes – and turn them into animations people can see and quickly understand.

Scientists are interested in learning how the vegetation (collection of plants) of an area can be used to study Earth's climate.

Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make false color images which allow us to see patterns more easily. Students will make a false-color image using a set of numbers.
