Grand Canyon National Park's free distance learning programs offer students an exciting introduction to the science behind the park.

Layers in Time engages the class in the geologic history of Earth through a live and interactive lesson with park rangers via the Internet. Students gain a better understanding of universal geologic principles and processes such as deposition, plate tectonics, and erosion. By exploring Grand Canyon's rock layers and formation, they come to recognize how landscapes change over time. The program lasts about one hour.

    "Excellent all over"


    It's a helpful assist for any teacher and very, very interesting for people wanting to teach themselves


    There are no cons


    I'm very grateful, that whoever cared to prepare the materials, have made the learning materials accessible in the Internet. And it' s - thank god - not so hidden but can be found easily. So it is very tempting, even when it is a distant learning experience, to delve deeper in the materials whichever are to be found. (e.g. Wikipedia) To tell the unexpected: I am writing from Southern Germany, Europe.
