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.

Learners will analyze and interpret a box plot and evaluate the spread of the data. Learners will compare it with a different visualization of the data to see how the two compare, discuss the limitations of the two types of data displays and formulate questions.

The purpose of this lesson is for students to create, analyze and compare histograms, box plots and scatter plots and evaluate the spread of the data. You can choose which types of graphs you want your students to complete.

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.

The fires in Greece during the summer of 2007 devastated large tracks of forest and ground cover in this Mediterranean region. Students analyze these data to determine the scale, area, and percentage of the forest impacted by of these fires.

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.

Students solve math problems to compare the carbon dioxide generated by the airline industry, a large volcanic eruption, and burning oil.

Students will use the NASA Earth Observations analysis tool to explore changing albedo in the Arctic compared with other areas of Earth.

Conduct this EO Kids mini-lesson with your students to explore the phenomenon of Urban Heat Island Effect.

Why do you think grass feels cooler than pavement? And how are materials in a city different from those you find in rural and wild areas? The answer is that the materials in our neighborhoods retain, absorb, and radiate heat differently.
