GLOBE protocols and learning activities that complement the Changes in Land Surface and Land Use Change phenomena through hands-on investigations are detailed.
Learn how Landsat data are used to detect changes in land use. This video describes how the data are interpreted and gives examples of changes in forests from different insects and differences due to land management.
Teachers, these mini lessons/student activities are perfect "warm up" tasks that can be used as a hook, bellringer, exit slip, etc.
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.
The purpose of this activity is to have students use an Earth Systems perspective to identify the various causes associated with changes to Earth's forests as they review Landsat imagery of site locations from around the world.
