They not only enjoyed this activity, but they really gained a better understanding of it as well.Use this decay calculator to easily calculate the time elapsed since the beginning of the decay, or calculate the original quantity, half-life or remaining quantity of a substance subject to radioactive decay, based on any of the three parameters.Convert half-life to mean lifetime or decay constant, and vice versa by entering any of the three values in its respective field.Our versatile radioactive decay calculator supports many different time units and automatically converts them if the time unit you measure the time elapsed is different than the time unit you enter the half-time, decay constant or mean lifetime in.Results are accurate to the 16-th decimal and are usable in physics, chemistry, etc. "nuclear decay", "radioactivity") is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, gamma ray, or electron in the case of internal conversion.
Adapted from: For Special Ed and ELL kids, you could give them a template of the data table/graph.
Students use M&Ms to demonstrate the idea of radioactive decay. Parent isotopes are represented by the M side up (radioactive).
