In recent years, new educational methods tend to combine subjects that were previously considered separate. One of the new educational approaches in the field of combining subjects is the STEAM educational approach. The term STEAM is related to the fields of science, technology, engineering, art, and mathematics education. The characteristic of the randomness of radioactivity in radioactive nuclear isotopes is seen in the quantity of half-life. In a dice-throwing activity, we simulate and count the number of radioactive nuclei after successive half-lives. By plotting the number of dice representing the active nuclei according to the experiment number, we try to get closer to the decay representation and derive a suitable definition for the half-life. In this lesson plan, some parts of the STEAM approach have been used. If the decay graph (exponential graph with negative slope) is correctly extracted and any distance between events on the horizontal axis is chosen as a time unit, the concept of half-life can be taught to the audience. For this purpose, the students will be asked to extract the duration of the halving of the number of radioactive nuclei from the drawn graph.
