One explanation of the ability of humans, particularly children, to survive near-drowning is a physiological mechanism known as the diving reflex. This reflex will serve as a springboard for review of important skills such as library and on-line searches, experimental design, critical thinking, graphing, and interpreting graphs. You will also be asked to recall what you’ve learned about regulation of the cardiovascular system, and apply it to a real-life situation. And you might need to know the cranial nerves!
