Presents some facts about conodonts, extinct eel-like animals whose fossils have been found in Indiana's marine sedimentary rocks. Their important role in geologic research is also discussed.

A fact card describing the characteristics of calcite and its presence in limestone, its chemical and physical properties, and the composition and structure of a calcite unit cell.

A fact card describing the properties and characteristics of pyrite, where it is found, its effects on its immediate environment, its chemical structure, and where it fits on Mohs hardness scale.

A colorful diagram of the rock cycle showing the stages that rocks go through as they are transformed by different processes such as weathering, lithification, and crystallization.

A simplified version of the rock cycle showing the three types of rocks and the transformational processes that occur between each pair of rock types.

Describes the formation of the Salem Limestone during the Mississippian Period.

Young scholars examine sedimentary rocks to determine how they form. In this Earth science lesson plan, students will make a rock by cementing small particles together. The young scholars will then compare their observations of...
