Entry Events

Events that will be used to introduce the project to students

The Case of the Disappearing Dose

A local hospital reports a critical error: a dose of radioactive iodine, used to treat thyroid cancer, has been left unattended. Students, as a rapid-response team, must analyze the decay rate and determine if the remaining radioactivity poses a threat to staff or patients, prompting an immediate investigation into half-life.

Half-Life Escape Room

The class 'accidentally' gets locked in a room that is set to 'decontaminate' using a fictional radioactive substance with a known half-life. Students must solve a series of half-life calculation puzzles to unlock the door before the radiation levels 'theoretically' reach a dangerous level, creating an engaging, time-sensitive learning experience.
