Half Life Analogue

A screw-top plastic container of 500, 10 mm cubes to be used to investigate the topic of half-life. Each cube has one face identified and the class is actively involved in “throwing” the cubes, which represent atomic nuclei to see how many “decay” during each throw.
Decayed nuclei are removed prior to the next throw and the results give an excellent exponential decay curve without the hazards of using radioactive sources.
