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.

For the laboratory portion of this lesson, you will have to set up the ring stands, rings, funnels, and graduated cylinders.

Fill the funnels with ice before the students arrive in the classroom.

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.

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.

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.

## Why Is Radiocarbon Dating Important To Archaeology?

His radiocarbon dating technique is the most important development in absolute dating in archaeology and remains the main tool for dating the past 50,000 years. Radicarbon.

## Carbon 14 Dating - Math Central

Archaeologists use the exponential, radioactive decay of carbon 14 to estimate the death dates of organic material. The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles. Carbon is naturally in all living organisms and is replenished in the tissues.…
