Artifact Ages—Radiometric Dating
Simulation—Super Value Kit
By: Annis Hapkiewicz, Retired Okemos High School, Okemos, MI
An archeological site in Flinnlandia was recently excavated and ancient artifacts were recovered! Now it’s time for your students to become “real-world” scientists, determine the age of the artifacts, and see how long ago this civilization lived. Students learn about radioactivity, radioactive decay, and the half-life of isotopes, and apply these prin- ciples to carry out the radiometric dating simulation. Students calculate the ages of four different artifacts by examining samples containing “parent” and “daughter” isotopes, represented by different colored bingo chips. Enough reusable materials are provided to make 15 “arti- fact” samples. Possible items representing actual physical artifacts are also suggested, but not provided. Includes complete instructions and reproducible student handouts.
Super Value Kit is complete for 15 student groups. All materials are reusable.
Carbon Dating Activity—
Super Value Puzzle
By: Bob Becker
Kirkwood H.S., Kirkwood, MO
Find out how archeologists reconstruct the ancient history of the Earth using radiocarbon dating to determine the age of artifacts—everything from nutshells to parchment maps! Students “piece together” the process of carbon-14 dating by arranging a set of story and picture tiles in a logical sequence to form a narrated storyboard. How are carbon- 14 atoms produced? Why does the C-14/C-12 ratio decrease when an organism dies? What are the equations for solving half-life problems related to radioactive decay? Use this creative puzzle activity to help students learn the basic principles and procedures involved in radiocar- bon dating. Includes ten sets of laminated puzzle sheets, reproducible student handouts, detailed background information, and comprehensive Instructor’s Notes. Puzzle pieces are reusable!
Super Value Kit is complete for 10 student groups. All materials are reusable.
