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,...

[Free Registration/Login may be required to access all resource tools.] Students investigate behaviors of waves, including interference, reflection, refraction, and diffraction.

This lesson involves an innovative strategy for introducing the concept of relative dating using a block of wood that has been painted, damaged, and nailed. The task for students is to analyze the order in which these events happened and...

This activity is an inquiry-based field investigation of the sedimentary geology of Lilydale Regional Park's brickyards area, a bluff and slope location near St. Paul Minnesota's Harriet Island and Cherokee Heights Park. Students...

Using the skills of a paleontologist, students are asked to match up lecturers with what day and time they teach, and how many students they have based on clues given from several different perspectives. In the second part of the...

Learn about geologic time, including the age of the Earth by putting it in terms of pages in a book.

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...

Discover the relative age of rocks by identifying sedimentary rock and observing its layers.

A resource highlighting the process of dating methods in archaeology. Look at Relative Dating and Absolute Dating systems.

Students discover wave interference, the phenomenon that occurs when two waves meet while traveling along the same medium.

This site, in German, offers numerous apps that illustrate common physics principles. Apps are organized into categories: mechanics, oscillations and waves, electrodynamics, optics, thermodynamics, the theory of relativity, physics of...

This is a glossary of terms and definitions used in Chapter 16: Oscillatory Motion and Waves from the AP Physics online text.

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 Required] Get a visual of how sedimentary rock forms through an interactive animation on this site. Also, test your understanding with a short quiz.

[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.] Rules for sedimentary rock formation.

[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...

[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.
