Relative Age Dating
Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.
Curated OER
Modeling Geologic Time
Students design, construct and interpret a model of geologic time and investigate change through geologic time.
Curated OER
Geologic Time Scale
For this geologic time scale worksheet, students use a word bank to complete the geologic time scale provided. Students fill in the chart as it relates to the geologic time scale.

Diversity of Life: Geologic Time Scale
Students investigate the history of Earth by creating a geologic time scale. In this Earth History lesson plan, students practice sequencing events in their life as a way to get familiar with creating a time scale. Students complete...
Curated OER
The Geologic TimeString
Students create a simple tool to visualize geologic time. They create knots to represent the K/T, P/T and Precambrian boundaries in a 4.6 meter string with each millimeter representing one million years. They then refer back to this...
Curated OER
Understanding the Geologic Timescale
Learners identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative to...
Curated OER
Geologic Time
In 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.

EarthViewer
Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion years ago to...
Curated OER
Relative Dating-Telling Time Using Fossils
Students 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. Students use bar graphs to...
Curated OER
Time Machine: Evolution, Geology
Students are taken on a simulated "voyage" backward in time, to the beginning of our planet. They "witness" that beginning, the origin of life, and a number of key events from then to the present.
Curated OER
PATTERNS IN TIME
Students build a realistic sense of geological time, seek clues of transition fossils and find them. In this investigative lesson students complete several activities and worksheets on fossils.
Curated OER
Relative Dating - Telling Time Using Fossils
Students use fossil range charts to explain relative dating. They graph for ammonites, marine organisms that went extinct at the same time as dinosaurs.
Curated OER
Rock On!
After five class sessions, young scientists will be able to identify common rock types: igneous, sedimentary, and metamorphic. This plan involves hands-on activities, includes various handouts and worksheets, and requires there to be...

How Old Is Mike?
Young scholars examine the absolute dating of fossils, they use a list of names and ages to determine the difference between relative age and absolute age. They explore the relative age and absolute age of people and of fossils.
Curated OER
VARVES: Dating Sedimentary Strata: Geology, Paleontological Patterns
Students count the number of varves (annual layers of sediment) in shale billets, taken from the Green River Formation in Wyoming. The count is then extended to reflect the entire 260 meters of sediments where the billets originated.
Curated OER
Determining Age Of Rocks And Fossils
Students discuss together how to determine the relative age of each of the rock units in the block diagram (Figure 1). After students have decided how to establish the relative age of each rock unit, they should list them under the block.

A Glacier Ran Through It
Students learn basic geological concepts while researching how ice age floods sculpted the plateau of the Columbia Basin. They synthesize their learning by creating annotated illustrations of the geological principles they studied.

A Basin Filled With Time
Learners use fossil leaves and a mathematical formula to study climate change. In this climate change and fossil lesson plan, students determine the differences in temperatures during two different times during the Cenozoic era using...
Curated OER
Geologic Time: Relative and Absolute Dating
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.
