Half-Life Analogue SetThis set is a great way to safely explore radiation decay with your students. Each set includes 10 bowls and 500 small plastic cubes, each with one coloured face. The coloured face represents the decayed nuclei when upright. This resource is designed for 10 groups shake the set of nuclei, roll them onto the bench, remove the decayed nuclei. This provides an exponential decay curve students can study. Explore the principals of chemistry and radioactive
