Questions for Discussion: Density and Buoyancy: Experimenting with Club Soda
How did the bubbles help the raisin and grape float? What gas is in the bubbles that form on the grape and raisin? In what ways is the bubble-covered raisin like a person in a life jacket? How can a life jacket be so small compared to our bodies and still keep us afloat? The grape and the raisin have very different volumes. Why do you think the air bubbles allowed both to float?
