The Lab Report. The rate of ossmosis and the surface area.

SBI 3UO Ms. C. Evans Biology Lab Report Title: To determine the effect of surface area on the rate of osmosis. Abstract: The main aim of the experiment was to determine the effect on the rate of osmosis by the changing surface area. The changes were observed in the masses and surface area of the chopped potatoes which were initially of different surface area but same mass. The rate of osmosis increased with increase in …

…the ordinary water which includes chlorine as a major component. Moreover one of the potatoes has a bump in one of its surface which must have changed its area. The error factor may also be increased as we only make one observation with each type group. But if we had made a three or four observations with each group the averaging must have reduced the error. The measuring tools used might also have some error.
