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

By the end of the 8th grade, students should know that all matter is made up of atoms, which are far too small to see directly through a microscope.They should also understand that the atoms of any element are alike but are different from atoms of other elements.Atoms may stick together in well-defined molecules or they could be packed together in large arrays.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 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).

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

The element carbon is an essential element in all living matter.

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.

Carbon-14 is produced constantly as our atmosphere is bombarded by cosmic rays.
