Fresh water resources- their quantity, location and distribution- are briefly discussed in this two-page article. The article can be used as a "reading to be informed" activity in a stand-alone fashion or can be incorporated into a lesson plan.
Derived from the Science on a Sphere film entitled "Water Falls," this short (2:50) video presents basic information on the percentage, allocation, and distribution of Earth's usable water.
This activity includes a presentation with links to videos about scientists and engineers working with NASA's Global Precipitation Measurement Mission (from the Faces of GPM series), as well as other STEM careers videos, followed by a number of... (View More) links to online career resources. It is designed to be used by students working at their own pace, choosing which videos and links they are interested in watching and exploring, but could also be used with a larger group. As part of the activity, students identify personal skills and abilities related to career interests and develop a career goal. Includes a student capture sheet with guiding questions. (View Less)
This set of three videos illustrates how math is used in satellite data analysis. The videos feature NASA senior climate scientist Claire Parkinson. Parkinson explains how the Arctic and Antarctic sea ice covers are measured from satellite data and... (View More) how math is used to determine trends in the data. In the first video, she leads viewers from satellite data collection through obtaining a time series of monthly average sea ice extents for November 1978 – December 2012, for the Arctic and Antarctic. In the second video, she begins with the time series from the first video, removes the seasonal cycle by calculating yearly averages, and proceeds to calculate the slopes of the lines to get trends in the data, revealing decreasing sea ice coverage in the Arctic and increasing sea ice coverage in the Antarctic. In the third video, she uses a more advanced technique to remove the seasonal cycle and shows that the trends are close to the same, whichever method is used. She emphasizes the power of math and that the techniques shown for satellite sea ice data can also be applied to a wide range of data sets. (View Less)
This article describes a citizen science project, Community Collaborative Rain, Hail and Snow Network (CoCoRaHS). Participants take and report daily measurements of precipitation at their location. SciJinks is a joint NASA/NOAA educational website... (View More) targeting middle school-aged children and their educators. It explores weather and Earth science through articles, videos, images, and games. (View Less)
This article explains the polar vortex: an area of low pressure (a wide expanse of swirling cold air) that is parked in polar regions. An explanation is also provided for high and low pressure systems. SciJinks is a joint NASA/NOAA educational... (View More) website targeting middle school-aged children and their educators.
