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
on this project!
can improve on this project by making
and testing your own hydrometer.
