Donna poured 120mL of water into each of six glasses, Donna dissolved one tablespoon of salt in each of three glasses, and did not add salt to the other three. Then, Donna
placed an egg in one glass and observed if the egg floated. She removed the egg and
dried it. She repeated the process with the other five glasses, recording each time if the
egg floated. Donna repeated this test with two more eggs and counted the number of
times the eggs floated in fresh water compared to salty water.
3. Which experimental question that best describes Donna's experiment?
A. Are eggs more likely to float in fresh water or salty water?
B. Does the amount of water in a glass affect whether eggs sink or float in the water?
