If I can say, I LOVE this lab! This lab using yeast to measure cellular respiration. The students truly like watching this lab, it allows them to prepare their own solutions, and watch little organisms eat sugar and "burp"!
On a teaching note, this allows students to get very hands on in their learning. This lab replaces the "yeast balloon lab" with more structure and the availability of data that can be used for graphing.
The lab moves pretty quickly paced, allows for collaboration, and ideal for groups of 2-3.
