Information from satellites if often used to display information about objects. This information can include how things appear, as well as their contents. Explore how pixel data sequences can be used to create an image and interpret it.
Scientific data are often represented by assigning ranges of numbers to specific colors. The colors are then used to make false color images which allow us to see patterns more easily. Students will make a false-color image using a set of numbers.
Students explore positive feedback effects of changing albedo from melting Arctic sea ice.
Students collect and analyze temperature data to explore what governs how much energy is reflected.
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.
This lesson walks students through the use of Landsat false-color imagery and identification of different land cover features using these as models.
