Entry Events
Events that will be used to introduce the project to studentsThe Case of the Malfunctioning Mitochondria
Students receive a mock medical report detailing a patient with a mysterious illness linked to mitochondrial dysfunction. They must work in teams to diagnose the patient, explaining the cellular processes affected and proposing potential treatments, sparking inquiry into organelle function and cellular respiration.Cellular Communication Breakdown: A Role-Playing Game
Students participate in a role-playing game where they simulate different cell types attempting to communicate under various stress conditions (e.g., viral infection, toxin exposure). This illustrates the importance of signaling pathways and the consequences of communication disruptions.Create a Cellular 'Art Gallery': Visualizing Disease
Students create visual representations (e.g., digital art, 3D models) of cells affected by specific diseases, focusing on how structural changes at the cellular level contribute to the pathology. This blends creativity with scientific understanding and connects cell biology to real-world health issues.Portfolio Activities
