A lab experiment: LET’S ANALIZE YEAST!

We are going to find out what conditions are best for the growth of yeast. We need 6 test- tubes, some yeast, some sugar, some water and some balloons. We put a small piece of dried yeast into each tube, we shake it to mix the content and we place a deflated balloon over the top of the tube. In one tube we put only yeast and in the others we add sugar and water (cold, warm or boiling) 
and we find out this

Do you know why some of the balloons blow up and others don’t?
Just send us an e-mail and explain the reasons!!!!
