Students will analyze the monthly seasonal chlorophyll concentration images in our global oceans for the four different months of 2017, and then answer the following questions.

Students observe seasonal images of Monthly Leaf Area, looking for any changes that are occurring throughout the year.

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 watch a video on the Greenland Ice Sheet and answer questions.

Watch the video and have students answer the questions about Earth's cryosphere.

Compare images from two volcanic eruptions in the Kuril Islands which occurred ten years apart and complete a graphic organizer for impacts on different Earth spheres. 

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

Students examine satellite images of a recently formed island to identify areas of erosion and deposition.

Watch NASA videos about aerosols and volcanic ash.
