While quartz crystals take tens of thousands of years to grow in nature, you can grow crystals of sugar in only a few days! In the process, students learn about saturated and supersaturated solutions, seed crystals, and the rate of crystalline growth. Included are all the materials to grow sugar crystals, along with a study guide. You will need to provide a saucepan, spoon, measuring cup, and a stove or hotplate.
