Explore the science of radioactive decay with a safe hands-on family STEM activity. As radioactive materials decay, or break down, they emit radiation that may be harmful. Unfortunately, the amount of time it takes for a radioactive material to decay varies. Scientists talk about the rate of decay in terms of the material's "half-life." Some materials have a very short half-life and others have a very long half-life. In this week's family science activity, students can simulate… Read more
