The document describes an experiment to observe osmosis in eggs by placing one egg in water and another in corn syrup. The student hypothesized that the egg in water would increase in weight and size due to osmosis, while the egg in corn syrup would decrease in weight and size. By measuring and comparing the weights and sizes of the eggs before and after being placed in water or corn syrup, the student observed that both eggs changed slightly, with the egg in corn syrup increasing in weight and size.
