Radioactive carbon dating worksheet

Technology is essential to science, because it provides instruments and techniques that enable observations of objects and phenomena that are otherwise unobservable due to factors such as quantity, distance, location, size, and speed.

Technology also provides tools for investigations, inquiry, and analysis.

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.

The idea behind radiocarbon dating is straightforward, but years of work were required to develop the technique to the point where accurate dates could be obtained.

Research has been ongoing since the 1960s to determine what the proportion of in the atmosphere has been over the past fifty thousand years.

This hands-on activity is a simulation of some of the radiometric dating techniques used by scientists to determine the age of a mineral or fossil.

The activity uses the basic principle of radioactive half-life, and is a good follow-up lesson after the students have learned about half-life properties.

Daughter isotopes are represented by the M side down (stable).Class size can vary, but activity should be done in groups of 2-3. The method was developed by Willard Libby in the late 1940s and soon became a standard tool for archaeologists.Read the passage in this science printable to learn about the history of radioactive dating and its uses.Students will answer comprehension questions and solve word problems using a table with information about the half-lives of radioactive elements.
