利用NASA卫星数据追踪水源
It’s Back to School Week and NASA has STEM activities to keep students motivated. In this image, students use real data from NASA’s GRACE satellites to track water mass changes in the U.S. Student activities include estimating water resources using heat-map data, creating a line graph for a specific location, then assessing trends and discuss implications.
