NASA’s Gravity and Climate Experiment (GRACE) is a mission to track the impact of climate change on the planet’s vast stores of freshwater, saltwater, and ice. A pair of satellites, GRACE effectively “weighs” Earth’s shifting water resources month by month to detect where water is accumulating or drying up. 

With these resources, students can explore real data to see for themselves how Earth's water is changing.
