Sugar Rainbow Density Experiment

The 2nd grade and 5th grade scientists in Ms. Scaperrotta’s and Mr. Iwaskiewicz’s classes collaborated on a colorful density project. Students used different ratios of dissolved Skittles candies to demonstrate the scientific property of density. You can try this experiment at home for a fun St. Patrick’s day activity! First, students sorted the Skittles by color. They gathered 10 purple, 8 green, 6 yellow, 4 orange, and 2 red Skittles in separate cups. Next, they added 2 teaspoons of water to each cup and stirred the candies until the sugar completely dissolved. Last, the students poured the liquids into a clean cup in this order: purple, green, yellow, orange, and red. The varying density of the sugar solution created colorful layers in the cup! The higher the sugar concentration, the more dense the solution! Some students were curious to know what it tasted like… Try this experiment at home and taste the density rainbow for yourself!
