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...

Create a little excitement with a radioactive resource! An engaging lesson builds a solid understanding of the nature of radioactive isotopes. The narrator explains the desire of a nucleus to become stable, which leads to radioactive...

A Geiger counter is used to detect emission of alpha particles, beta particles, and gamma rays. The teacher experiments to find out which materials block each of these forms of radiation. The camera is focused on the measuring instrument...

How do medical professionals use radiation without doing more harm than good? Budding nuclear chemists begin their study of all things radioactive with a video from the JFR Science playlist. Topics include differences between isotopes,...

Radioactivity is often perceived as dangerous and a threat to our well-being, but you may be surprised at the different applications of this natural chemical process. From the smoke detectors in our homes to treatments for cancer, this...

In this radioactive dating activity, students 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 radioactive...

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 learning exercise, 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...

Altering the subatomic nature of an atom affects its properties. The video illustrates the idea of an isotope using Carbon-12, Carbon-13, and Carbon-14 as examples. 

Use animations to explain the concept of an isotope. Young scholars view a lesson from the Reaction series dedicated to isotopes. They learn what an isotope is and why they are important to complete a great back-to-basics lesson.

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...

Who receives that greatest amount of radioactive exposure? After visiting some of the most radioactive places on earth, including Chernobyl and Fukushima, viewers consider the exposure of radiation workers, astronauts, and cancer...

Explore the science of radioactivity! A very thorough video lesson begins with an explanation of the chemical structure of radiation. It includes descriptions of benefits of radioactivity and half-life calculations.

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.

Why are people afraid of nuclear power plants? A video in the Veritasium playlist explains that radiation doesn't travel very far, yet people still worry. Then it discusses the possible release of radioactive atoms, which do travel a...

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...

Through colorful diagrams and simple text, viewers are introduced to nuclear radiation. They discover alpha, beta, and gamma rays; they balance nuclear equations. You will impart important information to your chemistry class and give...

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, students 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...
