  • Rock Candy: An Edible Study of Crystallization 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, which can be done at home using only 2 ingredients, helps students visualize how a supersaturated solution grows the extra-large crystals of sucrose needed to make rock candy. View »
  • Foaming Rainbow Demonstration In this demo, you add dry ice to a basic solution of dish detergent and universal indicator. As carbon dioxide is released from the solution, it forms bubbles with the dish detergent, producing a mass of foam. View »
  • Make Your Own Indicators Testing the pH of a solution is a fundamental skill in chemistry. A wide variety of pH indicators can be purchased, but effective pH indicators can also be made at home or in the classroom from items you probably already have in your kitchen or garden. Find out how to extract anthocyanin pigment from plant material for use as a natural pH indicator. View »
  • Super Water-Absorbing Polymers The molecular structure of polymers have very different rates of water absorption. This makes them ideal for teaching an engaging lesson on physical and chemical changes. View »
