In this lesson, students will simulate the randomness of decay in radioactive atoms and visualize the half-life of a sample radioactive element. This lesson can be completed in two (2) 45-minute class ...

Researchers have discovered an “unexpected” accumulation of the radioactive isotope beryllium-10, deep underneath the surface of the Pacific Ocean. The team hopes their discovery could serve as an ...
