The Feasting Yeast

We are doing an interesting experiment to find out what is a feast for yeast? Yeast doesn't make its own food, so it has to consume food from somewhere...but where?

Who knows which ingredient will activate the yeast? Will it be flour, salt, olive oil, or honey (sugar)? We are mixing yeast and one of the other ingredients and adding warm water to see which one activates the yeast...OR you could say gives the yeast a feast! 

Each group got one ingredient to mix with the yeast and water in a cup
We made observations then let the cups sit overnight 


The yeast and the sugar started looking like oatmeal! It was a tannish color and had big white and yellow bubbles. The next morning it smelled like wine and looked kind of like mold. We all thought the sugar must have been the feast the yeast was looking for!

The yeast and sugar CLOSE-UP...yikes!
