Carbon-14 is radioactive and undergoes radioactive decay.Radioactive materials contain some nuclei that are stable and other nuclei that are unstable.By extension, this experiment is a useful analogy to radioactive decay and carbon dating.Students use M&M’s (or pennies and puzzle pieces) to demonstrate the idea of radioactive decay.This experiment is best used by student working in pairs.Grade Level: 5-12 grade Disciplinary Core Ideas (DCI) 3-5ETS1-2, MS-ESS1-4, HS-ESS1-6 Time for Teacher Preparation 40-60 minutes – To gather materials Activity Time: 40-60 minutes (1 Class Period) Materials: Objectives Students try to model radioactive decay by using the scientific thought process of creating a hypothesis, then testing it through inference.All three isotopes have the same atomic number of 6, but have different numbers of neutrons.

The half-life of a radioactive isotope refers to the amount of time required for half of a quantity of a radioactive isotope to decay.

Groundwater is an increasingly important water resource in arid or semi-arid regions, as well as a conjunctive resource in humid environments.

Because of the long residence time for groundwater in the hydrologic cycle, the last few decades have seen expanding study of groundwater systems.

Isotopes have the same chemical properties, but different physical properties.

An example of isotopes is carbon, which has three main isotopes, carbon-12, carbon-13 and carbon-14.
