Earth Science Week Classroom Posters

Rachel Dye, Geoscientist in the Parks participant, at Cape Cod National Seashore.


Every year the Geologic Resources Division of the National Park Service partners with American Geosciences Institute to create an informative poster for the Earth Science Week Toolkit. These posters incorporate geologic concepts relating to America's national parks. They can be used as a classroom resource to help build understanding of key geologic concepts.

Past Earth Science Week posters are available to download for your classroom and present an introduction to many geologic themes associated with national parks.
