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...

In this geologic time worksheet, students 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.

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

In this waves worksheet, students define 23 vocabulary words associated with the different types of waves and how waves are measured. Students complete 23 matching terms with definitions and draw the superposition of two waves shown.

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.

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

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....

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...

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...

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.

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

By looking at an outcrop, students make observations and prediction about Earth's history in this activity. Students will also make hypothesis about the past environment based on the observations from the outcrop.

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

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.

[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...

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

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...

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...

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,...

Extensive information about the geology of the Grand Canyon. Looks at some principles of geology evident there, forces that have shaped its geological features, how its valleys and canyons were formed, the characteristics of the Colorado...

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...

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

[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...

This page provides a summary for each section of Chapter 16: Oscillatory Motion and Waves from the AP Physics online text.
