Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.

Who knew Snickers® could be used to teach science? Give your budding earth scientists a chance to explore the Law of Superposition, in addition to a well-earned snack.

For this rules of the game worksheet, students create a foldable demonstrating the laws of superposition and the principle of folding. Students will answer questions as it relates to rock layers and the principle of folding.

In this geologic history worksheet, students answer questions about the earth's history, about dating fossils, about layers of rocks and about unconformity.

[Free Registration/Login may be required to access all resource tools.] This study guide summarizes key principles used in relative dating. Includes a few questions to check for understanding.

This comprehensive study guide covers the main terms and concepts needed for an earth science unit on determining relative ages. Review questions are included at the bottom of the study guide.

This is an in-depth activity where students create a rock layer formation using different colors of playdough and investigate the types of folds and rock formations that might occur. They take core samples through anticlines and...

This site was created by two geoscientists. They explain the Principles of Geology. These are general rules, or laws, that are used to determine how rocks were created and how they changed through time. They are also used to determine...

This set of activities from the Milton J. Rubenstein Museum of Science & Technology has students investigating how relative dating and absolute dating methods are used to determine the age of rocks and fossils.

An 81-page slideshow that looks at the principles of geology with respect to relative dating, at different concepts describing geological processes, at absolute age and radiometric dating, at the eons and eras in the geologic time scale,...

In this amazing interactive tutorial you will learn about what methods are used by geologists to learn about the history of the Earth. Investigate a geologic time scale and learn about how scientists have developed and organized a record...

Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the...

[Free Registration/Login may be required to access all resource tools.] Introduces Steno's laws, which allow scientists to decipher the geological events that occurred and the order in which they took place, including how the relative...

[Free Registration/Login may be required to access all resource tools.] Looks at how stratigraphy can be used to determine the relative ages of rocks, how unconformities occur, ways to match rock layers in different areas, and how...
