I know that solids remain in the solution, when they dissolve.
I can name some materials that do and do not dissolve.
I can explain that when solids do not dissolve in water, filtering can separate them.
I can explain that when solids dissolve they break into particles small enough to pass through filter paper.
I can explain that solids in a solution can be recovered by evaporation. I know that there is a limit to how much solid will dissolve in a liquid. I know several factors that affect the speed at which a solid dissolves, e.g temperature, volume of liquid, motion.
