Radiometric dating lab exercise

Written below is the case as it appears on The Case of the Melting Ice student sheet.

The Case of the Melting Ice Frosty the Snowman lies melting in the funnels at your lab station.

You can refer to How Carbon-14 Dating Works, from How Stuff Works, to help you answer the question.

Patented mineral rights covering an area of approximately 69,451 hectares (149,338 acres).

(This page has been archived and is found on the Internet Archive.) In addition to using answers to students' Analysis questions and their graphs for evaluation, consider having them respond to the following in their science journals or as a homework essay: Pretend you are on a month-long field trip to dig for artifacts that might have been left from the pre-colonial period in the United States.

Write a letter to a friend explaining what radiocarbon dating is.

"Carbon-14 undergoes beta decay with a half-life of 5720 years.

On a separate sheet of paper, immediately record the volume of Frosty's melted remains (water) in your graduated cylinder and note the time on the clock.Make a data table and, at regular intervals (you decide how long), record the time on the clock and the volume of water in the graduated cylinder.Stop after about 30 minutes, unless Frosty has completely melted earlier.The exercise they will go through of working backwards from measurements to age should help them understand how scientists use carbon dating to try to determine the age of fossils and other materials.To be able to do this lesson and understand the idea of half-life, students should understand ratios and the multiplication of fractions, and be somewhat comfortable with probability.
