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.

The advance-and-retreat cycle of snow cover drastically changes the whiteness and brightness of Earth. Using two maps created using NASA satellite data for 2017, students review the seasonal differences of snow and ice extent and answer questions on their observations.

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.

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

Students will analyze a line graph that shows how the surface temperature and air temperature values change over the course of 24 hours.

Students will analyze the mapped plot of the historic Ocean Chlorophyll Concentrations at key locations around the world for the period of 1998-2018.
