More science with yeast

Today what more fun with yeast. Our question was: what type of sugar does yeast like the most? 

We experimented with white sugar, banana, apple, raisins and flour. We placed these in separate bags with yeast and warm water. Here's what happened..,

Our bags were labeled so we knew what was in them.

You can see that yeast produces the most carbon dioxide with white sugar. 

It produces some carbon dioxide with banana.

It produces a little carbon dioxide with raisins and apple. 

It doesn't produce much carbon dioxide with flour. 

We concluded that yeast likes white sugar the best. However, if you didn't want to bake with white sugar the next best option is banana.
