Curated OER
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
Measuring Absolute Time
In this absolute time learning exercise, students answer eleven questions about ways to measure the age of fossils. They define half-life, answer questions about radioactive dating, tree rings and varves.

Chapter 22 - 25 Review
In this chemistry review worksheet, students 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.
Curated OER
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
Nuclear Chemistry Homework Problem Set
In this nuclear chemistry worksheet, students evaluate data from concentration experiments on radioactive iodine. They graph the data, determine radioactive decay and half life for the element.
Curated OER
Radioactive Decay
Students explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms....
Curated OER
A Phylogenetic Perspective for the Cladistically Challenged
Students use M&Ms to simulate radioactive decay of elements.
Curated OER
Radioactive Decay/Half Life
Learners demonstrate radioactive decay using candy corns. In this Physics instructional activity, students make predictions, collect data and form conclusions about patterns in radioactive decay.
Curated OER
Nuclear-Powered Space Probes
In this space probes activity, learners read about radioisotope thermoelectric generators and how they work. Then students complete 3 short answer questions.
Curated OER
The Nucleus
In this atoms worksheet, students review terms associated with atoms which includes isotopes, transmutation, and radioactive decay. This worksheet has 11 short answer questions.
Curated OER
Using Radioactive Decay To Determine Age
Learners explore the process of carbon dating fossils to determine their age. They simulate radioactive decay using pennies in a shoe box. Heads represents a decayed atom each time they shake the box. They use the data to calculate the...
