Math in Medicine: Half-Life Activity

Grade 11ScienceMath1 days
In this project, students explore the concept of half-life and its applications in medicine by designing a simulation or game that models drug dosage and its effectiveness in treating a medical condition. They research half-life, calculate drug dosages, and design a simulation to teach the concept of half-life in a medical context. Students act as medical consultants, evaluating drug effectiveness, dosage requirements, and potential side effects based on half-life, and create a functional simulation prototype.
