Explore using units in calculations with the Leaf Area Index (LAI). LAI is a ratio that describes the number of square meters of leaves per square meter of available land surface. Because of the units in the ratio, it is dimensionless.
Explore using units for calculations with Normalized Difference Vegetation Index (NDVI). NDVI is a ratio of different light wavelength reflectance which can be used to map the density of green vegetation.
Students will review the NASA Space Place video, "Tectonic Forces", and answer questions about tectonic plates.
In this mini lesson, students use in-water profiles of historical ocean data to analyze how sea surface salinity varies with depth.
Review this page to learn about the background of volcanoes and their eruptions.
Students examine satellite images of an island before and after a volcanic eruption to determine the impact of the eruption.
This lesson is designed to help students analyze the interaction between different cloud heights and Earth's incoming and outgoing energy.
Carbon dioxide concentration in the atmosphere is affected by many processes including fires, deforestation, and plant respiration. Students will evaluate a Landsat image to determine the rate of carbon dioxide sequestration in a particular area.
