are some ideas for an excellent science project that is can be performed by either
middle or high school students. Fermentation of grapes is (also known as making
wine) can be a fun project to work which encompasses many areas of biology and
physics. Several colleges in the US give advanced degrees in Oenology (study and
science of wine) .
is the energy-yielding anaerobic metabolic breakdown of a nutrient molecule, such
as glucose, without net oxidation. Fermentation yields lactate, acetic acid, ethanol,
or some other simple product.
Fermentation refers to the fermentation of sugar to alcohol using yeast,
but other fermentation processes include the making of yogurt. The science of
fermentation is known as zymology.
fermentation of grapes occurs the density of the liquid decreases as sugar is
changed to alcohol. The change is easily monitored by wine makers using a hydrometer.
A hydrometer is an instrument used to determine specific gravity. By monitoring
the density of the liquid you are able in effect the monitor the fermentation
effect does temperature have on the rate of fermentation?
other microorganisms (aside from yeast) be used to produce fermentation?
is the effect of adding more sugar to the fermenting mixture?
does the rate of fermentation compare when different fruits are used?
on this project!
can improve on this project by making
and testing your own hydrometer.
