In this radioactive dating worksheet, 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 radioactive...

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.
