Half-Life
Scholars shake their way to understanding half-life with the help of candy. They observe and record which side candy lands on to graph the exponential decay in the fifth lesson of seven integrating chemistry and algebra. Combining...
Curated OER
Half-life Worksheet
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...

Working with Half-Life
In this half-life worksheet, students use a given table of half lives, mass, time and amount of original sample to solve for unknowns in nine given half-life problems.
Curated OER
Radioactive Decay and Half-Life
Learners 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...
Curated OER
Half Lives
Students investigate the concept of half-life by conducting an M&M experiment. In this chemistry instructional activity, students differentiate nuclear fusion and fission. They present investigation findings to class.
Curated OER
Chem 152-Nuclear Chemistry
In this nuclear chemistry worksheet, students answer ten questions about radioactive decay, half life, electron capture and alpha emission.
