What are Radioactive Isotopes (Radionuclides)
4 mins 9th - 12th
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...
Isotopes and Half-Life: What Are Medical Isotopes?
5 mins 9th - Higher Ed CCSS: Adaptable
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,...
How Old is it Really? - How Do We Know that the Earth is 4.6 Billion Years Old?
9th - 12th
Eight neat slides lead to the understanding of how geologists have determined Earth's age. Most of the slides are dedicated to explaining the absolute dating method of assessment. Color diagrams display radioactive isotopes and a graph...
Demonstrating the Half-Life of a Radioactive Isotope
8th - 10th
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...
Radiation vs. Radioactive Atoms
3 mins 9th - 12th CCSS: Adaptable
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...
Teaching Radioactive Decay: Radioactive Half-life And Dating Techniques
9th - 12th
Students 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.
