Using real data from NASA’s GRACE satellites, students track water mass changes in the U.S. over time. Students estimate water resources using heat-map data, create a line graph for a specific location, then assess trends and discuss implications.
5-ESS2-1 Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact. Clarification Statement: Examples could include the influence of the ocean on ecosystems, landform shape, and climate; the influence of the atmosphere on landforms and ecosystems through weather and climate; and the influence of mountain ranges on winds and clouds in the atmosphere. The geosphere, hydrosphere, atmosphere, and biosphere are each a system. Assessment Boundary: Assessment is limited to the interactions of two systems at a time.
This resource is explicitly designed to build towards this performance expectation.
Comments about Including the Performance Expectation In this lesson, students develop a model in the form of graphs that show monthly changes in water mass in the US over a period of 10 years using data collected by GRACE satellites. The satellites measure the strength of gravity to show the movement (interaction) of water (hydrosphere) on Earth's surface and underground (geosphere). The models developed are in the form of graphs that are depicting the changes in water mass with regards to snow, surface water and soil moisture.
This resource is explicitly designed to build towards this science and engineering practice.
Comments about Including the Science and Engineering Practice Students develop models collaboratively in groups based on evidence from data collected from NASA’s GRACE satellites to describe ways that the geosphere, biosphere, hydrosphere and/or atmosphere interact. Students use the data to create graphs to predict possible implications of evolving global water resources. The data has been collected over time to determine trends/patterns.
This resource is explicitly designed to build towards this disciplinary core idea.
Comments about Including the Disciplinary Core Idea The hydrosphere is the primary system discussed in this lesson, but the geosphere (concentration of subsurface water sources) is also included. GRACE satellites depend on the interaction of Earth's geosphere and the hydrosphere to determine the mass of water using the force of Earth's gravity. Including the possible implications that changing water data could have on the other Earth systems would strengthen this lesson.
This resource appears to be designed to build towards this crosscutting concept, though the resource developer has not explicitly stated so.
Comments about Including the Crosscutting Concept Students look for patterns by comparing data from multiple locations. The teacher will need to explicitly identify the crosscutting concept of systems, the components of the system and how they interact. Students could discuss possible differences between chosen locations with regards to the different Earth systems. Based on these comparisons, how might the data collected be affected by the interaction of these systems?
