Radioactive Simulations
Young scholars simulate radioactive decay and nuclear power using an on line interactive web site. In this on line lesson plan, students monitor radioactive isotopes and record the activity of a particular element as the decay...
Curated OER
Radioactive Dating
In this radioactive dating learning exercise, students use their reference guide in their text book to find the half-lives of 4 isotopes. They use a decay chart to help determine the half-lives and age of given bones and samples of...
Curated OER
Radiochemistry
In this radiochemistry instructional activity, students read about how scientists learn more about elements using radioactive isotopes. Students answer three critical thinking questions about the reading and radiochemistry.
Curated OER
Half-Life Problems
In this half-life worksheet, students calculate the half-life of isotopes, they find masses of isotopes remaining after specified times, and they find particular amounts of time needed to pass for given masses of isotopes to decay.
