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

Learners interpret archaeological strata using the law of superposition. They apply cross-dating to determine the age of other artifacts.

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.

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

In this geology worksheet, students locate 55 rock and mineral terms in a word search. Answers to the word search are available in various formats.

Learners analyze cross-sections of geologic events. In this geology instructional activity, students identify the type of environment where the cross-section come from. They take a quiz at the end of the instructional activity.

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...

How well do pupils play the role of geologist? Test their abilities in the first installment of a two-part series. Presented with a series of rock formation diagrams, learners write stories to match what they see in the diagrams. The...

Students investigae using radioactive decay to determine geologic age.

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...

Students visit the Caldecott Tunnel. They examine dark brown basalt and the gray-green sedimentary rocks and draw picture of the rock layers in the cliff face. In addition, they write a short paragraph describing what you observe about...

In this electrical worksheet, students interpret schematics to answer a series of 31 questions about mixed frequency signals. This worksheet is printable and the answers are available on-line.

In this electrical circuit learning exercise, students answer a series of 4 open-ended questions with schematics about audio control in stereos. This learning exercise can be printed and the answers are available on-line.

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

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

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.

In this math worksheet, students find a solution basis and compute the Wronskian for each of the equations. Then they sketch a graph of a typical solution.

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.

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.

Pupils try to reach a "best explanation" after viewing diagrams.  In this trackway lesson students complete several worksheets, make observations and hypothesize.

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.

By the end of this section, you will be able to determine the resultant waveform when two waves act in superposition relative to each other, explain standing waves, and describe the mathematical representation of overtones and beat...
