Curated OER
Determining the Age of Fossils
High schoolers examine the concept of radioactive dating. In this radioactive dating lesson, students investigate how to determine the ages of fossils and rocks as they learn about half-life radioactive decay.
Curated OER
work in pairs for the activities of this lesson which include researching and identifying butterflies, writing, and a brief oral presentation.
Students explore the concepts of rdioactive decay and dating. They generate a radioactive decay table, use their data to plot a decay graph, develop the concept of half-life, and then use the graph to find the age of a mummified seal in...
Curated OER
Absolute Ages of Rocks
In 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 paper.
Curated OER
Half Life Lab
Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.
Curated OER
Dating Popcorn
Students simulate the dating process with popcorn. In this geology lesson, students discuss how geologist find the age of rocks by gauging the amount of decay of radioactive elements. They have 6 bags of popcorn and each group microwaves...

Assessment & Evaluation
Seventh graders study elapsed time, radioactive decay and half-life. In this time machine lesson students complete several activities and view a presentation.
Curated OER
Earth System Science
Students investigate the age of the earth by using accepted scientific methods. They conduct research about the use of radioactive dating and there is a simulation activity of the process. Finally, students measure the radioactive decay...
Curated OER
Finding the Ages of Rocks and Fossils
Students practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.
Curated OER
Nuclear-Powered Space Probes
In this space probes worksheet, students read about radioisotope thermoelectric generators and how they work. Then students complete 3 short answer questions.
Pace University
Grades 9-12 Earth Science
How has Earth changed over time? Pupils explore the topic in a differentiated instruction unit on the geological time scale. After a pre-assessment to gauge knowledge, class members divide into groups based on their ability levels and...

WS 6.7 Effects & Applications of Nuclear Chemistry
In this nuclear chemistry learning exercise, students are given the biological effects of nuclear radiation. They are also given a list of uses of nuclear chemistry and Einstein's theory of special relativity to calculate the energy...
Curated OER
Date a Rock!
Students figure the number of half-lives since the sample solidified, and therefore the "age" of the sample rocks.
Curated OER
Absolute Ages of Rocks
In this rocks worksheet, students review the process of absolute dating of rocks and compare it to the relative dating process. This worksheet has 16 fill in the blank questions.
Curated OER
Half-Life Lab
Middle schoolers participate in a lab in which they are introduced to carbon-dating. In groups, they use the holes of paper from a hole puncher and determine the rate of retention after shaking coins onto the same area. They record...
