Teaching Tips | Science | Pedagogy |
- Background information about the Aquarius satellite mission at http://www.nasa.gov/mission_pages/aquarius/news/aquarius20110610.html.
- When used in the classroom, the video needs adequate scaffolding to focus students on satellites, remote sensing, climate, nature of science, or the topic of choice.
About the Science
- Sea surface salinity and sea surface temperature, which together determine seawater density, regulate ocean circulation.
- Computer models help to predict global temperatures, but ocean salinity is measured in a number of ways. NASA earth-orbit satellites, such as Aquarius, measure a wide variety of variables such as rainfall, surface wind, sea surface temperature (SST), sea level, and even ocean color. Observations like this help unlock the secret links between the ocean and climate.
- Comments from expert scientist: This activity describes how satellites measure sea surface salinity well and how the SSS measurements fit into the satellite oceanography constellation, including describing how the instruments work and what extra measurements need to be taken in order to make the most accurate assessment of SSS.
About the Pedagogy
- Teacher can reinforce nature of science principles during the video. The video itself serves as a great visualization to support a discussion of the importance of satellite observations in computer model development.
- The video can also be used to show students how satellites work, how scientists observe the Earth from space (remote sensing), and how the ocean dynamics are measured.
- The transcript at http://aquarius.nasa.gov/pdfs/aquarius_climate_transcript.pdf can be used by hearing impaired users.
