Absolute Ages of Rocks
In this ages of rock worksheet, students review the processes involved with determining the ages of rocks which includes the radioactive decay of carbon-14. This worksheet has 5 matching and 5 short answer questions.
Curated OER
work in pairs for the activities of this lesson which include researching and identifying butterflies, writing, and a brief oral presentation.
Learners 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...

Chapter 22 - 25 Review
In this chemistry review worksheet, learners explore their knowledge of solutions, acid and bases, nuclear reactions, and radioactive decay as they answer 33 matching, fill in the blank, and short answer questions.
Science 4 Inquiry
Layers and Laws: The Law of Superposition and Index Fossils
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...
Curated OER
Radioactive Decay
Students generate a radioactive decay table for an imaginary element, use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

Half Life Analogy
Eighth graders explain half life. In this hands on activity, 8th graders use licorice to explain radioactive decay and graph their results.
Curated OER
Geologic Time: Relative and Absolute Dating
Young scholars 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.
