Questions for Discussion: Density and Buoyancy: Mixing Hot and Cold Water
Why did the warm water float on top of the cold water? What would happen if you reversed the bottles, placing the one with warm water on top? What do you think would happen after an hour? After four hours? How would the temperatures compare then? Would you have been satisfied with the cast member's explanation if he had not done the second "control" experiment? Are there more "control" experiments you would have liked him to try?
