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 engage in a collaborative learning routine as they explore slides that show how the development of public transportation infrastructure changed the land in Woodlawn, Maryland. They will make observations of a satellite image and a photo from the ground as well as read background information on the impact of urbanization.
In this activity students will examine NASA data to determine the differences between a solar and lunar eclipse.
In this activity students will compare different methods for observing the Sunās corona and make predictions about what they will observe during the April 8, 2024 total solar eclipse.
In this activity students will make observations about the objects, size, distance, and motion of the Sun, Earth, and Moon during a solar eclipse.
Students analyze a graph that illustrates the change in global surface temperature relative to 1951-1980 average temperatures.
Students analyze surface air temperature anomalies to identify change with respect to different latitudes across the world.
