All three isotopes have the same atomic number of 6, but have different numbers of neutrons.It is a great introduction to the scientific process of deducing, forming scientific theories, and communicating with peers.It is also useful in the mathematics classroom by the process of graphing the data.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.

Description: With the Half-Life Laboratory, students gain a better understanding of radioactive dating and half-lives.

Students are able to visualize and model what is meant by the half-life of a reaction.

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

Students then should be able to see the connection between the M&M’s and Puzzle Pieces and radioactive elements in archaeological samples.

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