I am working on a science fair project about yeast fermentation in different liquids. I have done plenty of research and am working on my Experiment Plan. I was just wondering if you knew of any good sites to use. Also, what kind of yeast should i use for my experiment? Lastly, i am measuring the most active fermentation by the CO2 produced which i will measure with water displacement. Is there a formula to convert the water displacement to an actual air measurement?

I found a good website it is: http://www.newton.dep.anl.gov/askasci/m ... e00195.htm try it out

Hello,
First of all, what do you mean by air measurement? I think it would be fine if you measured the amount of CO2 through the water displacement method.
To do this, you can place the yeast in a large container with the liquid you are testing the fermentation in; have a graduated cylinder or flask and fill it with water, and stopper it. Invert it into the water and take out the stopper; make sure you keep the cylinder/flask directly over the yeast that is fermenting, so as to collect the CO2 being produced. This method is based off of a lab I did in Chemistry that dealt with the collection of butane gas. More information can be found here: http://serendip.brynmawr.edu/sci_edu/farber/pdf/bic.pdf
Hope this helps!
