So, objects older than that do not contain enough of the isotope to be dated.

This process, known as carbon dating, was developed by the American chemist Willard Libby in 1947 at the Institute for Nuclear Studies at Columbia University.

Libby and others (University of Chicago) devised a method of estimating the age of organic material based on the decay rate of carbon-14.

is the quantity of radioactive material at time zero, X is the amount remaining after time t, and k is the first order rate constant, which is a characteristic of the isotope undergoing decay.

This is a slide and worksheet for radioactive dating and half life activity.

The Slides are to be shown at the front and then each item is shown in turn and the pupils use their graphs to calculate the age of each item from the percentage of carbon found in them. take longer than you think, but keeps them engaged and there're questions to be answered in their books also.
