The Rocks Under Illinois
The goal of this fine geology lesson is to have learners create a map that shows how the rock layers are arranged far underground where they can't be seen. The ambitious lesson plan requires high schoolers to learn the law of...
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.
Curated OER
Absolute Ages of Rocks
For this age of rocks worksheet, students answer five matching questions about terms related to the decay of atoms. They use a strip of paper to simulate half life of atoms and determine the total amount of time it took to deplete the...

How Old Is Illinois?
High schoolers use fossils found in rocks to determine the age of rock in Illinois. They use a chart to identify the fossils and then identify the periods of rock.
Curated OER
How Old Is Illinois?
High schoolers use fossils found in rocks to determine the age of the strata between Rock Island and Chicago. Pupils pretend they are geologists. They must determine the age of all rock layers between the Mississippi River and Lake...

Are All Asteroids' Surfaces the Same Age?
There are more than 600,000 asteroids in our solar system. Pupils analyze images of two asteroids in order to determine if they are the same age. They count craters for each asteroid and compare numbers.
Curated OER
Sandwich Stratigraphy
Two activities are included in this resource. In the first, junior geologists model sedimentary rock layers, apply the Law of Superposition, and demonstrate folding and faulting of the Earth's crust. The model is technically a sandwich....
Curated OER
Geologic Age
Learners investigate radioactivity as a tool for measuring geologic time and how geologists use this information to determine the absolute age of rocks or minerals.
Curated OER
It's All in the Rocks
Students think critically to determine fact or inference when examining sedimentary layers with embedded fossils. They are being introduced to geology as well as evolutionary biology.
Curated OER
Absolute Ages of Rocks
In this ages of rock instructional activity, students review the processes involved with determining the ages of rocks which includes the radioactive decay of carbon-14. This instructional activity has 5 matching and 5 short answer...

Are All Asteroids' Surfaces the Same Age?
Did you know scientists can tell the age of an asteroid by looking closely at its craters? This final lesson of a six-part series focuses on two asteroids, Gaspra and Ida, in order to demonstrate the concept of dating asteroids. Scholars...
Curated OER
Relative Aging Study Guide
In 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.
Curated OER
Geologic Age
Students investigate rocks. In this geologic age lesson plan, students conduct an experiment to determine absolute age as one would for rock layers. Students graph data and problem solve using results.

Using Radioactive Decay to Determine Geologic Age
Pupils investigae using radioactive decay to determine geologic age.
Virginia Department of Education
Determining Absolute Age
How can radioactive decay help date old objects? Learners explore half-life and radioactive decay by conducting an experiment using pennies to represent atoms. Young scientists graph data from the experiment to identify radioactive decay...

Relative Ages of Rocks
In this rocks instructional activity, students review how sediments are layered over time and how the relative ages of rocks are determined. This instructional activity has 1 matching and 11 multiple choice questions.
Curated OER
Rock of Ages
Students use a video, the Internet and hands-on activities to explore how to determine the age of rocks and fossils based on radioactive decay data.
Curated OER
A Geological Puzzle
Students compare and contrast the various types of rocks on each continent. In groups, the calculate the rock ages and types to determine if the continents, in their opinion, were joined at one time. They develop two imaginary...
Channel Islands Film
Island Rotation: Lesson Plan 3
How far have California's Channel islands moved? What was the rate of this movement? Class members first examine data that shows the age of the Hawaiian island chain and the average speed of the Pacific Plate. They then watch West of the...
