Your students will be talking about this lab for years to come! Not really "barf", but the mixture of cereal, yeast, and water sure looks like it when the sandwich bag bursts open! This quick and easy lesson is perfect for life science or biology students learning about cellular respiration or fermentation.
This inquiry lab involves very little preparation. Because the fermentation process takes 1/2 to 1 hour, it is best to set up the lab, let it run for most of the class, then watch the bags POP as the carbon dioxide builds! *This lab is not as messy as it sounds. The bags do not explode, but they will pop and dribble fermented cereal on your lab table.*
You will not be disappointed by this unique and memorable lab!
