The "Salt vs. Sugar" formative assessment explores students' thinking about the question "How does structure influence reactivity?" I wanted to know whether ice melts faster with salt, sugar, pepper or water on its own. It is a matter of bringing warm water into contact with the surface of the cube (this happens with the tap water because of convection) and layering of the cold, colored melt on top of the denser solution (little convection of the bulk fluid here).
