Students use chocolate in this activity to model sedimentary, metamorphic, and igneous rocks, mimicking what happens during transformations in the rock cycle.

Young scholars use their knowledge of the rock cycle to write a story about a pet rock. The story must include the rock changing from magma, to each type of rock igneous, sedimentary, and metamorphic. The story should end with the pet...

Explains what graded bedding is and how it forms in sedimentary deposits.

Instructional module focusing on the rock cycle. Discussion includes the concept of uniformitarianism and how earth materials change from one form to another. The site also includes an interactive practice quiz and links relating to the...

This interactive resource adapted from the National Park Service describes the many forces that affect shorelines, including tides, weathering, erosion, and deposition. Includes background reading handout and discussion questions.

The rock cycle consists of igneous, sedimentary, and metamorphic rocks. This lesson will focus on metamorphic rocks and how they form. This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded...

Read about the pioneers in Earth's geologic history and their discovery of how the process of uniformitarianism shaped the study of evolution.

Describes the three different types of rocks and provides a diagram showing where they fit into the rock cycle.
