Hold Your Breath!

hold your breathby Vikram Baliga and Sarah Baumgart

This module helps students learn about the mammalian dive response. Students simulate a dive by submerging their faces in cold water for 30 seconds. They measure heart rate and body temperature before and after the “dive”. Students learn how the human body responds to stress (cold water) and they convey their findings using bar graphs and a final lab report.

 

 

 

Fellow Vikram Baliga produced this video to accompany his Dive Response module for inquiry-based education in high school science lab.
