Human Body Systems Phenomena-Based Lesson: Pufferfish Tetrodotoxin Paralysis Presentation | Biology | Grades 9–12

This is the student-facing slide presentation that introduces the phenomenon, walks the class through observations and driving questions, and frames the evidence students will use for the Phenomena-Based Lesson in the high school Biology (grades 9–12) chapter Human Body Systems, built around the phenomenon Pufferfish Tetrodotoxin Paralysis. It is sold separately from the other two parts of the set.
