Nuclear Chemistry and Radioactivity— Demonstration Kits
Half-Life Simulation—
Classroom Activity Kit
By: The Flinn Staff
Roll the 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 modeled by another random process, the rolling of dice. In this cooperative activity, students will first weigh 100 dice. A decay number for the dice is selected and the 100 dice are rolled. The dice that “decayed” (landed on the decay number) are separated and the mass of the remaining dice is recorded. The “unde- cayed” dice are rolled again and the entire process is repeated eight more times. Students determine the half-life by graphing the mass of dice remaining after each round. This is a fun alternative activity for students to study the principles of radioactive decay. Demonstration Notes, extensive background information, and reproducible student worksheets are included.
Concepts: Radioactive decay, probability, half-life, first-order rate. Time Required: 15 minutes
Materials Provided: Six-sided dice (100), data table transparency, decay curve transparency.
Nuclear Fission—Demonstration Kit
By: The Flinn Staff
What exactly is a nuclear reaction? How is it possible
for so much energy to be released so quickly? Demonstrate the prop- erties of a nuclear chain reaction with this creative domino-toppling activity. The demonstration starts with two sets of 112 dominoes laid out in separate patterns. One set of dominoes is arranged in a straight line. The second set of dominoes is laid out on a specially designed template, so that each domino has two dominoes in its path. When students time each event, they discover it takes several seconds to completely topple all the dominoes in a straight line. The domino-chain reaction in the second arrangement, however, is over in the blink of an eye!
Concepts: Fission, chain reaction, neutron capture.
Time Required: 20 minutes
Materials Provided: Domino tiles, fission tile location template.
Radon Test—Demonstration Kit
Radon is a colorless, odorless, tasteless radioactive gas formed by the natural decomposition of uranium. Radon may be found natu- rally in soil, rock formations, water or air. Radon poses no risk when released outdoors. The problem occurs when radon gas is released into a confined area like your basement at home. The short-term test kit (two- to four-day test period) allows you to “screen” the home for possible radon problems. Once the radon screening test kit is exposed, it is sent to the laboratory. An analysis of the kit is completed and you are sent a detailed report. The lab analysis and report are included in the purchase price of the kit. There are no additional charges. Includes the Flinn publication titled “Radon Safety,” which provides an excellent introduction to the study of radon.
Concepts: Radioactivity, decay series, alpha radiation. Time Required: Two- to four-day test period Materials Provided: Radon tester.
