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.

There were no eyewitnesses, but there are several suspects. You need to determine the exact time at which Frosty was put into the funnels to melt away, leaving no trace.

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.

Be sure to include how radiocarbon dating works backwards to solve a puzzle.

Explain to your friend how you and other archaeologists, with the help of chemistry, determine how old your discoveries are.

You can continue to fill the funnels as different classes arrive.

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.This lesson is the third in a three-part series about the nucleus, isotopes, and radioactive decay.The first lesson, Isotopes of Pennies, deals with isotopes and atomic mass.Students should complete the Analysis section of the lab sheet, which will be used as part of their assessment.Advise students to read through the case first so that they understand what they should do.Carbon-14 is produced constantly as our atmosphere is bombarded by cosmic rays.
