The document describes an experiment to observe osmosis in eggs. The student hypothesized that an egg placed in water would get larger and heavier, while an egg in corn syrup would also get larger and heavier. Measurements showed the water egg increased in size and weight as expected, but the corn syrup egg decreased in size and weight, contradicting the hypothesis. The experiment demonstrated how osmosis causes water to diffuse across a membrane from an area of high water potential to low.
