This is a Ranger in the Classroom (RIC) program. It is based on the Earth sciences curriculum for 4th grade. A park ranger will visit your school and deliver an interactive presentation followed by a classroom activity. Depending on your class schedule, the ranger can deliver multiple programs for each class/section, or a single presentation for all sections at once.

The Weathering, Erosion and Tower Formation program covers the major Earth science topics for upper elementary grades. We review rock types and how changes to rocks occur over time. Deposition and types of erosion and weathering are reviewed in relation to the Tower's formation theories. The classroom activity allows students to investigate rock samples and learn more about types of rocks (and fossils) common to the Tower region.

Standard classroom equipment needed: computer and projection system for the ranger, pencils and workspace for the students. To request a program, go to the program request page and click "Request a ranger visit to your school."
