The student conducted an experiment where they placed one egg in vinegar to remove its shell, and then placed the eggs in either corn syrup or water solutions. They measured and weighed the eggs both before and after being placed in the solutions. The egg in corn syrup decreased in weight and size as the corn syrup solution had a higher concentration than the egg, while the egg in water increased in weight and size as the water solution had a lower concentration. The student's hypotheses about the effects of the solutions on the eggs were incorrect.
