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...

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...

Some isotopes are unstable, or radioactive, meaning they will decay over time and turn into another isotope or stable element. In the interactive simulation, participants manipulate elements to create isotopes and gather information....

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....

In this half-life worksheet, students use 100 pennies to simulate radioactive isotopes and half-life. They place the pennies in a box and shake the box. All pennies that turn up tails are removed from the box. They represent the isotopes...

Thanks to this game, teaching isotopes will never be the same. Physical science scholars work their way toward understanding isotopes in an entertaining game. Pupils play rummy in groups while practicing good sportsmanship and creating...

Lead your class through the amazing world of isotopes as they investigate the various properties they contain and further understand their respective location on the periodic table. They explore half-lives and radioactivity as each...

In this radiochemistry worksheet, students read about how scientists learn more about elements using radioactive isotopes. Students answer three critical thinking questions about the reading and radiochemistry.

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...

Students describe an isotope and radioactive isotope in a written essay. They describe how a specific country or region was affected by radioactive contamination and attempt to sympathize with those affected by these radioactive...

Radioactive isotopes have a wealth of uses, but their waste may cause some concern. One of four free-response questions challenges learners to devise a waste removal strategy for medical radioactive substances. Other questions address...

In this half-life worksheet, learners determine how long it takes for a 100g sample of AU-198 to decay to 6.25g. Then they determine the half-life of a radioactive isotope if a 500.0g sample decays to 62.5g in 24.3 hours. Students also...

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...

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 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 half-life learning exercise, students calculate the half-life of isotopes, they find masses of isotopes remaining after specified times, and they find particular amounts of time needed to pass for given masses of isotopes to decay.

In this half-life worksheet, students determine how much of the radioactive isotopes will remain after a certain amount of time. This worksheet has 11 problems to solve.

Students explore the Chernobyl incident and the resulting environmental health impacts. They explore three different isotopes that were released into the atmosphere. Through inquiry, students determine the difference between types of...

In this nuclear decay worksheet, students read about alpha and beta decay and the isotopes formed by the reactions. Students solve nine problems including writing the equations for the decay of radioactive isotopes, identifying the...

Students demonstrate that isotopes of an element have different masses. They illustrate atomic mass and neutrons. The periodic table is examined in length. Display of a collection of atoms is surveyed.
