The ocean's surface is not level, and sea levels change in response to changes in chemistry and temperature. Sophisticated satellite measurements are required for scientists to document current sea level rise.
Students identify and classify kinds of land cover (such as vegetation, urban areas, water, and bare soil) in Landsat satellite images of Phoenix, Arizona taken in 1984 and 2018.
Students collect and analyze temperature data to explore what governs how much energy is reflected.
In this activity, students will compare the methods scientists use to study the Sun, including drawings made during a total solar eclipse in the 1860ās, modern coronagraphs, and advanced imagery gathered by NASAās Solar Dynamics Observatory.
This lesson walks students through the use of Landsat false-color imagery and identification of different land cover features using these as models.
