Radioactive Decay

Students explore what radioactive decay is and are able to relate it to the concept of half-life. They are given 100 green beads that represent radioactive atoms and 100 white beads that represent stable, non-radioactive daughter atoms. The green beads are placed in one cup and the white beads in another. They are asked to do two trials, one sampling 8 beads and the other sampling 4 beads at a time.
