Review the animation showing seasonal chlorophyll concentration as it relates to net radiation.
Students observe seasonal images of Monthly Normalized Difference Vegetation, looking for any changes in vegetation that are occurring throughout the year.
Carbon dioxide concentration in the atmosphere is affected, among other things, by processes involving forests including fires, deforestation and plant respiration. Evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
In this mini-lesson, students analyze soil moisture quantities associated with Hurricane Harvey around Houston, Texas on August 25, 2017.
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.
The Eyjabakkajökull Glacier is an outlet glacier of the Vatnajökull ice cap in Iceland that has been retreating since a major surge occurred in 1973. Students analyze these maps to identify the scale, rate of change, and volume affected by the glacier retreat.
Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017.
The students will review the NASA Space Place video, "What are Tectonic Plates?", and answer questions about tectonic plates.
