Today we looked at the relationship between a concentrated solution and its density. Students investigated 4 mystery solutions to determine their densities and rank them in order. To do so, they tried layering the liquids in a straw so that the lightest (least dense) liquid was on top and the heaviest (most dense) was on the bottom. Students were surely engaged! Now, they know that if a balance or scale isn't around, they can use density to find the level of concentration of a solution.
