RAHWAY — Rahway Middle School students in Colleen Tombs’ science classes used paper chromatography to analyze and identify the candy coating on M&Ms and Skittles. To begin, students studied chromatography or the separation of components in a mixture. Using water-soluble markers, the eighth graders separated the components that make up a marker.

Students then used the same technique on Skittles and M&Ms. By the end of the investigation, students learned that the dyes that make up the colors on the candy coating will always separate in the same order and have a similar chromatogram. Students discovered that chromatography works because substances in a mixture move at different rates through an absorptive material.
