Carbon Dating Questions
Carbon 14 is a common form of carbon which decays over time. The task requires the student to use logarithms to solve an exponential equation in the realistic context of carbon dating, important in archaeology and geology, among other places. Note that the purpose of this task is algebraic in nature -- closely related tasks exist which approach similar problems from numerical or graphical stances. In either case, it is more appropriate to report the time since the plant has died as approximately 19, years since these measurements are never completely precise. If we evaluate this expression on a calculator, we get a value of approximately 19, years since the plant has died. Carbon 14 dating. Student View. Task Carbon 14 is a common form of carbon which decays over time.
When we speak of the element Carbon, we most often refer to the most naturally abundant stable isotope 12 C. Although 12 C is definitely essential to life, its unstable sister isotope 14 C has become of extreme importance to the science world. Radiocarbon dating is the process of determining the age of a sample by examining the amount of 14 C remaining against its known half-life, 5, years. The reason this process works is because when organisms are alive, they are constantly replenishing their 14 C supply through respiration, providing them with a constant amount of the isotope.
This is an A-level worksheet from Flipped Around Physics, on carbon dating. Worksheet answers are available from the Flipped Around Physics website. The worksheet is designed to be used in a flipped learning setting. Students can be directed to the Flipped Around Physics website to watch quality video material on the topic. Students can then attempt to answer the questions on the worksheet prior to a lesson. Lesson time can be spent checking and consolidating understanding.
Carbon Dating: Questions Answered
Radiocarbon dating also known as carbon dating or carbon dating is a technique for determining the age of an organic object by utilising the properties of radiocarbon, a radioactive isotope of carbon. Willard Libby developed the method at the University of Chicago in the late s. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants via photosynthesis; animals then acquire 14C through plant consumption.
