United States Geological Survey

This visualization depicts the global water cycle. It includes how human water use affects where water is stored, how it moves, and how clean it is.

Teaching Tips

  • Consider presenting the blank copy (worksheet) to a classroom of students that have a preliminary understanding of the water cycle and have them complete the diagram with their own knowledge. Use this to start a discussion about the difference between pools and fluxes, and fresh and salt water.
  • Ask students to think about how this diagram represents a global cycle, and encourage them to understand that water is a global resource. Then, move into a discussion about how humans effect the water cycle through climate change and industrial/modern activities.
  • Make sure to check out all available resources including the "Pools and fluxes in the water cycle" graph (https://labs.waterdata.usgs.gov/visualizations/pools-and-fluxes/index.html#/). Consider identifying local or regional systems that the general labels in this diagram could be applied to.
  • Consider visiting the USGS Water Science School website provided in the resource for definitions and more information about the water cycle: https://www.usgs.gov/special-topics/water-science-school/science/water-cycle

About the Content

  • This comprehensive diagram depicts the global water cycle and will familiarize students with lesser known concepts like "saline lakes", "brackish wetlands", "pools", and "fluxes" in addition to core concepts like evapotranspiration, groundwater, precipitation, and reservoirs. The accompanying text contextualizes these concepts and prompts students to think about how humans impact the water cycle through climate change and industrial and agricultural activities.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • A fillable version of this diagram can be used to test student knowledge of the water cycle (available as a worksheet in Spanish and Enlgish).
  • This resource can be used to teach new concepts about the water cycle for younger users, or promote discussion about the transformations that water undergoes throughout the built and natural environments (i.e., pollution and contamination, eutrophication via agricultural water run-off). Educators may use the "zoomable" visualization to zoom in on a specific area.
  • This resource should provide an excellent visual for teachers focusing on the water cycle.

Technical Details/Ease of Use

  • If internet connectivity is an issue, materials can be downloaded. This resource downloads quickly and with appropriate resolution in all available formats (PNG, PDF).
  • This resource is technically sound and easy to use.
