Toss 100 pennies (or poker chips or any other two-different-sided objects) and remove all of those displaying tails. Line them up and repeat. The lines of pennies collected get smaller each time, successfully representing half-life.
High schoolers simulate radioactive decay and nuclear power using an on line interactive web site. In this on line lesson plan, students monitor radioactive isotopes and record the activity of a particular element as the decay...
Four activities demonstrate the chain reaction of nuclear fission to your physical science fans: falling dominoes, snapping mouse traps, throwing paper wads, and igniting a series of matches. They perform additional laboratory activities...
A student-created, yet comprehensive 37-slide presentation on the life and contributions of Marie Curie awaits your upcoming chemists! With plenty of photographs, this resource introduces the woman who is responsible for our early...

Explain the importance of radioactive half-life as your high school biologists demonstrate the concept by performing a series of steps designed to simulate radioactive decay. Pupils use pennies to perform an experiment and gather data....
As physics masters view this presentation, they learn how nuclear power is used in submarines. They use Google Maps to plot a course through the ocean and calculate the time required for surfacing and traveling. They learn about fission,...
In this radioactivity worksheet, students answer 40 questions about half life, isotopes, radioactive decay, the uses of radioactivity, nuclear equations and the scientists associated with radioactivity.
In this radioactive decay and half-life learning exercise, students use given half-lifes to calculate the amount of time it will take for certain amounts of elements to decay. They also find the age of samples and determine how many...
Students describe how the mass of a radioactive isotope changes with time and the factors that affect the rate of radioactive decay. They write nuclear decay equations to represent natural transmutation. This activity is accomplished...
Learners generate a radioactive decay table for an imaginary element using a box filled with pinto beans and M&M's. They use their data to plot a decay graph, develop the concept of half-life, and use the graph to "age" several samples.
For this radon and radioactivity worksheet, high schoolers analyze the data of the isotopes of elements that occur in the decay series of uranium-238. Students answer 6 questions about the isotopes, their half-lives, their potential...
In this radioactive dating worksheet, high schoolers use their reference guide in their text book to find the half-lives of 4 isotopes. They use a decay chart to help determine the half-lives and age of given bones and samples of...
In this nucleus and radioactivity worksheet, students collect class data and the students represent radioactive atoms decaying. They plot their data and answer two questions about the results. They solve seven problems given the half...
Uranium 235 has a half-life of over 700 million years and is the fuel used in the atomic bomb dropped on Hiroshima, Japan. Pupils see the half-lives and decay rates of Carbon-14 and Uranium-238. They also take measurements of these two...

Make your lesson on radioactive decay pop with this lab exercise. Using popcorn kernels spread over a tabletop, participants pick up all of those that point toward the back of the room, that is, those that represent decayed atoms. As the...
In this nuclear chemistry worksheet, students define radioactivity and the types of nuclear reactions. They label nuclear reactions with one of five types of reactions including fusion, fission, induced, natural decay or electron capture.
At the end of a general physics course focused on light and electricity, you can administer this exam. Concepts covered include electromagnetism, circuits, induction, light rays, lenses and mirrors, characteristics of light, electron...
In this science worksheet, students focus upon the vocabulary terms focused around the theme of radioactivity. The answers are found by clicking the button at the bottom of the page.
Learners study the difference between types of ionizing radiation and how elements are transmuted. They determine that radiation is normal and surrounds us. They calculate the amounts of alpha, beta and gamma radiation emitted from a...
Mmmmm! Radioactive "candium!" Nuclear physics or chemistry classes use M&M'S® to demonstrate the process of radioactive decay. Individuals pour out a bag of candies and record the number that fall M-side-up to represent the number of...
