September 10, 2009 Why dead fish float

We studied microorganisms and bacteria today in the context of why fish float after they die. We mixed warm water, yeast and sugar in ziploc bags that Mrs. B had drawn fish on and then placed them in a trough of water. As the day progressed, we checked on our "dead fish" and watched them bloat and eventually float.
