Students describe and interpret images. They make a simple sketch of an outcrop shown in a slide (or computer projection) then discuss possible interpretations.

Students examine the rock layers in Illinois. They draw the many rock layers using the Geology website. They discover the arrangement of strata of rocks.

Students investigate relative and absolute dating; determine the difference between the two dating systems; and apply this knowledge by creating a geologic timetable of their own.

Students create a timeline that explains how ancient cultures used artifacts. In this Relative Dating in Archaeology lesson, students examine artifacts and draw conclusions about their origins. Then students analyze antiquated objects or...

For this geologic time worksheet, high schoolers review how fossils were formed and the events that mark the various geological eras and periods. This worksheet has 10 fill in the blank and 9 short answer questions.

One of the most fundamental principles of archaeology is the Law of Superposition. This website provides a diagram showing you the Law of Superposition.

After a study of the principle of original horizontality and the law of superposition, and how to determine the ages of rock layers and how they are formed, young scholars go on a field study to observe and gather information about rock...

Using a cake analogy, this activity teaches concepts such as: geologic time, rock layers, fossils, Law of Superposition, and relative dating. Activity can be modified to grade level and appropriate content for students,

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...

A detailed set of exercises (downloadable) that guide students in developing an understanding of how scientists have created the geologic time scale.

A lengthy scholarly article that discusses the geologic time scale, its history of development, age-dating events that occurred in different eras, and how absolute and relative dating are used to assess the ages of the Earth and Moon....

Learning about charge and forces of attraction will be keys to understanding electrostatics and the basis of this learning unit. Developing a greater understanding of charge and the charge model is necessary to understanding electricity.

[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...

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

[Free Registration/Login may be required to access all resource tools.] Rules for sedimentary rock formation.

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

[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...

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...

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

[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.

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.

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...

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...

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,...
