Teaching Tips | Science | Pedagogy | Technical Details

Teaching Tips

  • Can be used as general overview or review of the water cycle.
  • Educators may wish to provide students a question sheet to keep student interest or ensure the video is watched all the way through.
  • Although this video does not directly articulate that water is a short-lived greenhouse gas, this is an excellent description of how one of the greenhouse gases (water vapor) impacts climate.

About the Science

  • Very basic overview of how the sun drives the water cycle and the interdependence between the water cycle and the climate system.
  • Emphasis on water in the atmosphere and how ocean currents transfer heat from the topics to higher latitudes.
  • Features interviews with several NASA scientists who study water and climate dynamics.
  • Comment from expert scientist: This video is accurate and explains the water cycle effectively and clearly. It traces the cycle in a linear fashion and marshals data, figures, and expert interviews to support its claims.

About the Pedagogy

  • One can use this video to review or introduce water-related activities, focusing on evaporation and water in the atmosphere.
  • The video uses a variety of images, diagrams, and data products to drive home how the water cycle and climate are impacted by changes in one or both processes.

Technical Details/Ease of Use

  • Well-produced and easy-to-use introductory video.
