Different isotopes have different half-lives and sometimes more than one present isotope can be used to get an even more specific age of a fossil.This is a slide and worksheet for radioactive dating and half life activity.
They can date rocks by gauging the amount of decay of radioactive elements.
It is also useful in the mathematics classroom by the process of graphing the data.
Students should begin to see the pattern that each time they “take a half-life,” about half of the surrogate radioactive material becomes stable.
Through this simulation, they will gain an understanding of how scientists are able to use isotopes such as U-235 and Pb-207 to determine the age of ancient minerals. Science helps drive technology, as it addresses questions that demand more sophisticated instruments and provides principles for better instrumentation and technique.
Technology is essential to science, because it provides instruments and techniques that enable observations of objects and phenomena that are otherwise unobservable due to factors such as quantity, distance, location, size, and speed.
