During the week, we have been exploring what yeast does in baking. How it can make something Chometz or not.

First we made Matzah with just flour and water. It didn't rise! It turned into a flat cracker-like bread. 

When the Jews were leaving Egypt, they were so excited to leave that they took the dough they were making on their backs and left. The hot desert sun baked it instantly into a flat cracker like bread called Matzah.

We decided to experiment and see if the sun would bake the Matzah that we put outside.

Then, in honor of Shabbat, we made Challah from scratch and noticed that it turned out nice and fluffy because of the yeast.
