Teaching Radioactive Decay: Radioactive Half-life And Dating Techniques
Students generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.

What is the Relationship Between Radioactivity and Radon?
In this radon and radioactivity worksheet, students analyze the data of the isotopes of elements that occur in the decay series of uranium-238. Students answer 6 questions about the isotopes, their half-lives, their potential threat and...

What is Radioactivity?
Students use a geiger counter to record changes in the amount of radioactivity produced by different objects. They research articles which mention radiation and discuss them. They work together to complete an activity and worksheet.

The Uses of Radiation
No visual aids, no activities, and no demonstrations accompany this plan. What you will find, is background information for a short lecture on the use of isoptopic radiation in the medical field and in our everyday lives. Should you...

NUMB3RS Activity: A Matter of Half-Life and Death
Students investigate exponential decay. Students explore the biological half-life of Cesium-137. Students investigate the Goiania Accident of 1987 which is considered one of the worst incidents in the history of the Atomic Age.

Growing Barley for Use in Biosynthesis Experiments
Students attempt to determine the optimum growing conditions for barley. They assess the effects of a number of substances such as ammonium chloride and urea on the plants

Exponential Decay
Young scholars study exponential decay and its application to radiocarbon dating. In this exponential decay lesson, students use candy to model the time it takes for something to decay. Young scholars also graph the data they collect and...

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.
