Carbon 14 dating worksheet answers


When an organism dies it ceases to replenish carbon in its tissues and the decay of carbon 14 to nitrogen 14 changes the ratio of carbon 12 to carbon Some things you'll be assessed on include which radioisotope of carbon is used in carbon dating, the length of the half-life of carbon, and what you can determine about isotopes based upon half-life. At any particular time all living organisms have approximately the same ratio of carbon 12 to carbon 14 in their tissues. If the amount of carbon 14 is halved every 5, years, it will not take very long to reach an amount that is too small to analyze. So, the fossil is 8, years old, meaning the living organism died 8, years ago. After 5, years, the amount of carbon 14 left in the body is half of the original amount. How old is the fossil? Carbon is naturally in all living organisms and is replenished in the tissues by eating other organisms or by breathing air that contains carbon. This lesson covers the following topics: Experts can compare the ratio of carbon 12 to carbon 14 in dead material to the ratio when the organism was alive to estimate the date of its death. This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50, years ago. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. In the case of radiocarbon dating, the half-life of carbon 14 is 5, years. When finding the age of an organic organism we need to consider the half-life of carbon 14 as well as the rate of decay, which is —0. The half-life of a radioactive isotope describes the amount of time that it takes half of the isotope in a sample to decay. We can use a formula for carbon 14 dating to find the answer. Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers. Radioisotope of carbon used in carbon dating Length of the half-life of carbon What you can determine about isotopes based upon half-life How many half-lives a radioactive isotope has before scientists consider it gone Items that cannot be dated using carbon dating Skills Practiced Information recall - access the knowledge you've gained regarding the radioisotope of carbon used in carbon dating Knowledge application - use your knowledge to answer questions about the characteristics of carbon dating and what it may be used to date Interpreting information - verify that you can read information on half-life related to carbon dating and interpret it correctly Additional Learning To learn more about this method of radiometric dating, review the accompanying lesson called What is Carbon Dating?
