Curated OER
Half-life Worksheet
In this half-life instructional activity, 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....

Demonstrating the Half-Life of a Radioactive Isotope
In this half-life instructional activity, 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...
Curated OER
Radioactivity Experiments
Students 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...

The Uses of Radiation
No visual aids, no activities, and no demonstrations accompany this plan. What you will find, is background information for a short lecture on the use of isoptopic radiation in the medical field and in our everyday lives. Should you...

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