Sink or Float Egg Experiment

Physics and Astronomy

Sheri Smith

Students were curious why some objects sink while other objects floated. In this experiment, students observed what an egg will do when put in fresh water versus salt water. Students were surprised when they saw the egg in the saltwater float because they said that the egg is heavy so it should sink. It took a lot of discussions and explanations but students began posing questions on what other objects would do if we put them in water and we could test other objects in the future to see if they sink or float.
