Questions for Discussion: Density and Buoyancy: Making Eggs Float
How did the ZOOM cast members decide how much salt to add? Why did they decide to use salt? What did they need to measure to compare the densities of salt and fresh water? How did weighing the water help them compare densities of salt and fresh water? Try this activity with sand instead of salt. Does an egg float in a mixture of sand and water? Why or why not?
