Carbon-14 has 2 more neutrons than carbon-12 and 1 more than carbon-13, both of which are stable.

Carbon-14 is radioactive and undergoes radioactive decay.

It is also useful in the mathematics classroom by the process of graphing the data.

Students should begin to see the pattern that each time they “take a half-life,” about half of the surrogate radioactive material becomes stable.

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

Flows, Cycles, and Conservation Objectives Students try to model radioactive decay by using the scientific thought process of creating a hypothesis, then testing it through inference.

If two nuclei have different masses, but the same atomic number, those nuclei are considered to be isotopes.

To develop the idea that carbon dating is based on gathering evidence in the present and extrapolating it to the past.

Students must get the questions correct before proceeding to the next page.

Did any group still have candies remaining after Trial 7? The element carbon is an essential element in all living matter.

The class has a debriefing after finishing the worksheet.

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. Summary This is a simulation of radioactive decay which illustrates what a half-life is and explains some of the carbons dating lab activity involved with radiometric dating. The carbon decays, with its half-life of 5, years, while the amount of carbon remains constant in the sample.

Rather, the atoms decay at a rate that is characteristic to the isotope.
