Nuclear Shielding—Super Value Kit
By: The Flinn Staff
The most comprehensive radioactivity shielding
kit available! Using a safe, low-level radioactive source and radiation monitor, students determine the shielding effectiveness of a wide range of materials. Students will quickly recognize the differences in the penetrating power of alpha, beta, and gamma radiation. Kit includes 2 thicknesses of shielding squares for aluminum, lead, copper, wood, polyethylene, and acrylic, along with reproducible laboratory procedure and background information.
Super Value Kit is complete for six student groups. All materials are reusable. Radiation monitor and sources required, but not provided.
Radioactive Decay Cards—
Super Value Game
By: Purkis, Sumprer, Distante and Adler, Tappan Zee High School, Orangeburg, NY
Nuclear stability and radioactive decay are important concepts for understanding nuclear chemistry, the size of the nucleus and the energy that holds it together. In this engaging activity, students will determine the natural decay of uranium-238 to lead-206 by arranging element cards and beta and alpha particle cards to create the uranium-238 decay series. Detailed Instructor’s Notes and Radioactive Decay Series Cards are provided.
Super Value Game is complete for six student groups. All materials are reusable.
Radioactivity Half-Life Simulation—
Super Value Laboratory Kit
By: The Flinn Staff
Students model the process of radioactive decay by studying the “decay curves” for a variety of multi-sided dice. Radioactive decay is a spon- taneous 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 desig- nated 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 Instructor’s Notes with sample data and answers to all questions.
Super Value Kit is complete for 15 student groups. All materials are reusable.
