The document describes an experiment to observe osmosis in eggs. Students placed eggs in vinegar to remove the shells, then measured and weighed the eggs. One egg was placed in corn syrup and one in water. After 24 hours, the egg in corn syrup shrank in size and weight, while the egg in water gained size and weight. This was because water moved into the egg in water due to lower water concentration, and out of the egg in corn syrup due to higher water concentration, demonstrating osmosis.
