Carbon dating half life problem sap updating delivery address

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.

As radioactive isotopes of elements decay, they lose their radio activity and become a brand new element known as a daughter isotope.

By measuring the ratio of the amount of the original radioactive element to the daughter isotope, scientists can determine how many half-lives the element has undergone and from there can figure out the absolute age of the sample."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.

Atoms are made up of much smaller particles called protons, neutrons, and electrons.
