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...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

Learners record data, make observations, and share in experimentation and discussion of numerical experiments.

Students write and balance nuclear equations. For this chemistry lesson, students identify materials that block radiation using polymers. They collect and analyze data from the experiment.

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...
