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.Plants take in atmospheric carbon dioxide by photosynthesis, and are ingested by animals.So, every living thing is constantly exchanging carbon-14 with its environment as long as it lives. The carbon in its body will remain until it decomposes or fossilizes.Libby calculated the half-life of carbon-14 as 5568, a figure now known as the Libby half-life.Following a conference at the University of Cambridge in 1962, a more accurate figure of 5730 years was agreed upon and this figure is now known as the Cambridge half-life.

Carbon dioxide also permeates the oceans, dissolving in the water.

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.

The amount of carbon-14 gradually decreases through radioactive beta decay with a half-life of 5,730 years.

So, scientists can estimate the age of the fossil by looking at the level of decay in its radioactive carbon.
