Synopsis
In this lesson, students graph data collected by NASA's GRACE satellites and look at trends in the water mass of different locations.
Students learn how the satellites use the concepts of gravity and mass to track water, why tracking water is increasingly important, and how water content has changed over a decade.
The videos, animation, and maps make this lesson great for visual learners.
The graphing portion of the lesson is an excellent practice in collaboration with every small group responsible for a different year of data.
Additional Prerequisites
There is a lesson on how to read heat maps linked in the Management section that teachers may want to use before doing this activity.
Students should know how to graph data along an x- and y-axis.
It may benefit students to understand the water cycle.
Differentiation
Language arts students can write an informational piece to explain how the GRACE satellites work and what they measure.
Geography classes can discuss how the trends in water in different locations will impact the people who live there.
Students can discuss how climate change impacts the water cycle, sea level rise, and glacial melt.
Younger classes who struggle with independently graphing the data can complete the graphs as a whole class, doing one or two years a day, and possibly gradually releasing responsibility as students become familiar with the process.
Some students may need to spend more time with the definitions and explanations for mass and gravity before understanding how the satellites work.
