Investigating the powers of yeast

We listed all the things we thought we would need for our dough.  But what about the yeast? 

What's yeast? Why do we need it?


I know let's wake up the yeast with some warm water and make it active!  Then let's feed it some sugar and see what happens next.

What does yeast do?

The yeast gave off a gas called CO2 and the water went frothy on the top.  The gas blew up our balloons. In bread it makes have the holes we saw some already cooked bread.
