 We wanted to see how yeast was best activated. To do this we used 3 conical flasks, a teaspoon of yeast in each one, some warm water in each one and some sugar in one flask. Then put a balloon in each flask. We found out that the flask that had the yeast and sugar inflated the balloon. It showed that when yeast has sugar it activates and creates a gas called carbon dioxide gas.
