Expeirimenting with yeast
The answer to our which was how do different liquids affect yeast? we concluded that liquids and chemicals mixed with the yeast caused a doughy smell to the drinks. the most effective liquid to the yeast was the coca cola soda it caused the most foulest odor.
Our evidence was the change of water levels and smells, we observed that the liquids and smells caused the liquid with most odor already, caused the most foulest smell. our sugar water vial smelled the most like yeast but the salt water smelled like rotten yeast.
The errors or inaccuracies that happened was we didn't exactly plan the yeast data and collecting and forgot to get balloons to measure and collect data.
We observed that overtime the liquids got more and more disgusting smelling and that the yeast pretty much sent off doughy smells to all the liquids.
I understand that the yeast did affect the liquids in smell and appearance, and i think i learned a lot about yeast.
some questions i have for our expeirement is....
why did the yeast stay on the bottom the whole time?
why did some of the vials lose water and not gain it?
why in some vials were bubbles gathered at the surface.
