There are several fun and inexpensive ways to explore science with children, such as observing crystal growth with homemade rock candy. This experiment requires minimal supplies or equipment, and it can easily be performed at home with adult supervision.
The rock candy experiment takes about a week to complete and demonstrates crystal growth in a super saturated solution. With adult supervision, students pour 1 cup of water into a pan and bring to a boil. Slowly add 2 to 3 cups of sugar, 1/4 cup at a time, allowing the sugar to dissolve until the water is completely saturated. An adult should pour the cooled solution into a tall glass or jar, and then suspend a wooden skewer or clean chopstick into the solution by placing a clothespin across the top of the jar. Crystals begin to grow in about 3 days, and the rock candy will be ready to enjoy by day seven.
