For over 20 years, satellite instruments have measured the sea surface height of our ever-changing oceans.  This video of images shows the complicated patterns of rising and falling ocean levels across the globe from 1993 to 2015.

Grade Level: 3-5 , 6-8 , 9-12

Students observe images of daily average sea surface temperatures taken during 2017, as they analyze the plots for evidence of changes that are occurring throughout the year.

Grade Level: 3-5 , 6-8 , 9-12

This mini-lesson guides students' observations of soil moisture anomalies (how much the moisture content was above or below the norm) for the continental US in May 2018.

Grade Level: 6-8 , 9-12

The radar measurements made by NASA's Soil Moisture Active Passive (SMAP) observatory are sensitive to whether land surfaces are frozen or thawed. Students analyze two maps of SMAP data to make inferences about changes to the Arctic's Geosphere showing spring thaw.

Freshwater is found in lakes, rivers, soil, snow, groundwater and ice, and is one of the most essential of Earth's resources, for drinking water and agriculture. However, the distribution of freshwater around the planet is changing.

Can you tell El Nino from La Nina? This interactive was created by UCAR Center for Science Education using satellite images of the height of the ocean surface.  Students interpret these images to identify whether they represent El Nino, La Nina, or neither event (La Nada!).

Mini lessons are intended to be short engagement activities that teachers may assign as bell-ringers, exit slips, or parts of larger learning lessons. These include activities where students interact with NASA maps, graphs, and datasets from the atmosphere, biosphere, cryosphere, geosphere, hydrosphere and the earth system.
