Product 12872

By: The Flinn Staff

In the Radioactivity Half-Life Simulation Super Value Laboratory Kit, students are given a set of dice along with a designated “decay” number. Students conduct a series of dice rolls and determine the “half-life.”

Product Details

Students model the process of radioactive decay by studying the “decay curves” for a variety of multi-sided dice. Radioactive decay is a spontaneous and completely random process. The probability that a specific atom will decay after a certain period of time can be simulated by studying the random process of rolling dice. Students are given a set of dice, ranging from 4-sided to 20-sided dice, along with a number designated as the “decay” number. Students then conduct a series of dice rolls, each time recording the number of decayed dice. The “half-life” is then determined by graphing the number of dice remaining after each roll of the dice. The variety of dice allows students to simulate a wide range of half-lives, from very long to extremely short. Includes 100 plastic coins and 150 multi-sided dice, along with reproducible student handouts, detailed background information and complete Teacher Notes with sample data and answers to all questions.

Super Value Kit is complete for 15 student groups. All materials are reusable!

Performance Expectations

MS-PS1-1: Develop models to describe the atomic composition of simple molecules and extended structures.
MS-PS1-2: Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-4: Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.
HS-PS1-4: Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
