Rock Candy: An Edible Study of Crystallization
An Investigation of Supersaturated Solutions Making rock candy is a safe way to introduce students to solutions and crystal growth–and you can make it a tasty treat at the same time! This activity helps students visualize how a supersaturated solution grows the extra-large crystals of sucrose needed to make rock candy. Table sugar (sucrose) and […]
