Development Say to students: The element carbon is an essential element in all living matter. Carbon is produced constantly as our atmosphere is bombarded by cosmic rays. It is incorporated into the carbon cycle, so that all living things, including you, contain radioactive carbon Living things have about 15 disintegrations per minute per gram of carbon.

Because living things constantly interchange carbon atoms, the amount of carbon remains constant, but when organisms die, no new carbon enters the organism. However, the carbon that was in the organism at death continues to disintegrate. By measuring how much carbon is left in a sample as well as its radioactivity, we can calculate when the organism died. It's a way of working backwards to solve a puzzle. In this activity, you will work backwards to solve a puzzle, much like scientists work backwards to find the time that an organism died.
You may group them in any size group, but working in pairs is optimal for this exercise.Using M & M's to Demonstrate Radiometric Dating
