Teaching Tips

  • Main points are well-outlined in the text of the video, which could be easily turned into talking points or questions for further discussion.
  • Note to educator: click on the "GPM Mission" link in the upper right for more context and background information.
  • Other hydrological cycle resources to complement video may be found at http://pmm.nasa.gov/education/subtopics/hydrologic-cycle.

About the Science

  • This video explains not only the dynamics of the hydrological cycle but also the transfer of energy throughout the cycle, and the influences of temperature, sea surface winds, and other atmospheric variables on the movement of water through Earth's system.
  • Color-coded satellite imagery introduces students to a variety of factors related to the water cycle.
  • The animations provide excellent visualizations, based on real world data, that are coordinated with an explanation of components of the water cycle.
  • Passed initial science review - expert science review pending.

About the Pedagogy

  • The video is accompanied by a short description and video transcript. The video moves fairly quickly through topics which may need to be outlined and reviewed prior to watching, such as evapotranspiration, condensation, and precipitation; how atmospheric rivers transport water horizontally across Earth's surface; and how water vapor is different from a water molecule.

Technical Details/Ease of Use

  • Well-developed simple video with good quality.
  • Download time may be slow for some internet connections; pre-downloading is a good idea for classrooms.
  • This video is based on data from NASA's Global Precipitation Measurement mission collected by its satellite, the GPM Core observatory. The home website is http://pmm.nasa.gov/education/.
  • Video and transcript are copied from another NASA page, http://svs.gsfc.nasa.gov/cgi-bin/details.cgi?aid=11054 , where it can be downloaded.
  • For additional information and an animation of the satellite in orbit, visit NASA Eyes on the Earth http://eyes.nasa.gov/earth/.
