There is Fungus Among Us !

This week we have been investigating dormant yeast. When yeast has favourable environmental conditions it wakes up.

 What does yeast look like ?

 When yeast has favourable environmental conditions it wakes up.
We added warm water and a sugar cube for food. We saw the mixture fizz and foam up and over the sides of the cups.
It smelled a bit like beer or bread. The bubbles were a chemical reaction making the yeast release the  carbon dioxide.

What did it look like ?

The next day the yeast had dried up a lot .The foaming had released most of the carbon dioxide by the next morning.

Our next challenge is to think of a way to change the experiment and predict what might happen.
