The half-life of a radioactive isotope refers to the amount of time required for half of a quantity of a radioactive isotope to decay.Carbon-14 has a half-life of 5730 years, which means that if you take one gram of carbon-14, half of it will decay in 5730 years. The ratio of the amounts of carbon-12 to carbon-14 in a human is the same as in every other living thing.Students then should be able to see the connection between the M&M’s and Puzzle Pieces and radioactive elements in archaeological samples.Seeing this connection will help students to understand how scientists can determine the age of a sample by looking at the amount of radioactive material in the sample.Understand how decay and half life work to enable radiometric dating.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.This activity was selected for the On the Cutting Edge Reviewed Teaching Collection This activity has received positive reviews in a peer review process involving five review categories.The five categories included in the process are 75 students).

It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers.An example of isotopes is carbon, which has three main isotopes, carbon-12, carbon-13 and carbon-14.All three isotopes have the same atomic number of 6, but have different numbers of neutrons.Rather, the atoms decay at a rate that is characteristic to the isotope.The rate of decay is a fixed rate called a half-life.
