Students observe monthly images of changing vegetation patterns, looking for seasonal changes occurring throughout 2017. These data can be used by students to develop their own models of change.

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.

This activity invites students to simulate and observe the different effects on sea level from melting sea-ice.

Students model Earth's tectonic plate movement and explore the relationship between these movements and different types of volcanoes.
