Explore how NASA observes and measures fresh water from space. Find out why Lake Mead appears to have a bathtub ring around its shoreline and how less snow in the mountains means less drinking water for California. Explore satellite images of where fresh water is stored in and on the Earth. Discover what NASA does in the field with an update from scientists on the Olympic Mountain Experiment (OLYMPEX) campaign.
EO Kids offers hands-on activities, experiments and more. The Maker Corner provides instructions for making a model aquifer and a self-watering planter. Explore the science behind fresh water with a snowmelt experiment and be a data detective by analyzing satellite data like a scientist. Kids can even create their own data visualization by coloring in a map showing ice thickness on Greenland.
