Annotation: Through this site, I was able to learn how fermentation is used to make various foods such as beer and wine.
Fermentation yield
Amount of fermentation is affected by:
temperature
fermentation time
After researching this, I learnt that fermentation is a method of microbial food production
Variables
Independent
T
Fermentation time
Annotation: I learnt that fermentation time can affect
Dependent
Fermentation yield
Through research I learnt that bubbles in yeast are made of CO2, this could be the DV in my investigation
Measure the volume of the CO2 bubbles using a ruler
