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)
