What can layers of rock teach us about the climate? Young scientists solve a mystery about who stole a cookie by applying the law of superposition. Then, they apply the same concept to solve a more difficult mystery, trying to determine...

Learners explore how to read fossil range charts. They develop an knowledge of the strengths and weaknesses of the fossil record. Students become familiar with the concepts index fossil and fossil range. Learners use bar graphs to...

For this fossils and the Law of Superposition worksheet, students fill in 4 blanks with the proper terms that match definitions about fossils and rock layers. They complete 9 questions about 2 activities they performed related to the age...

Students examine the geological time scale: the Earth is ancient; time can be divided into periods based on its fossil content.

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

Every living creature can leave a fossil record, yet most fossils belong to extinct organisms rather than ones currently living. Scholars learn about dating rock layers, fossils, and the environment of the past. Pupils understand that...

Seventh graders study the law of superposition by creating models of fossils in layers of rock. They examine how fossils are usually found in sedimentary rock which leads to the study of geologic history in those rocks.

For 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 identify the law of superposition and it states that beds of rock in a series are laid down with the oldest at the bottom and younger layers on the top. They construct a legen for a block diagram and construct a block diagram...

In this geological history worksheet, students define 17 terms associated with index fossils, nuclear decay, and radioactive decay.

In this relative aging worksheet, students define relative time and absolute time and define the laws and "rules" related to studying the age of fossils and rocks.

For this relative age worksheet, students define relative time and absolute time and define the laws and rules of determining the age of rocks and fossils.

Students read about and complete question activities for the topic of relative dating. For this relative dating lesson, students read information for the topic and then complete two activities to further their understanding of geologic...

In this rocks worksheet, high schoolers review how sediments are layered over time and how the relative ages of rocks are determined. This worksheet has 1 matching and 11 multiple choice questions.

Seventh graders examine how the different layers of rock show the history of the Earths surface.  In this rock lesson students divide into groups and complete an activity using clay.

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.

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 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,

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,...

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...

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....
