Yeast Experiments.

Our question was...

"How does sugar affect the growth of water?"

We had two bottles, warm water, sugar, and yeast.

We mixed the ingredients and waited to see what would happen.

We didn't have to wait long.

Within four minutes our mixture was bubbling and foaming.

Our second bottle had warm water, yeast but no sugar.

This one had a small amount of foaming.

We then made up another bottle and put in warm water, yeast, and sugar.

We put a balloon over the top and waited.

The balloon was soon filling up with gas and some of the foaming mixture.
