This hands-on activity walks through paper chromatography, a technique used by chemists to separate mixtures or in forensic crime analysis to investigate evidence. Paper chromatography can be applied outside of the lab too! Here, we use the method to show what types of dyes make up different colored markers. Is purple truly made of red and blue?
We want to see your work! Take a photo or video and upload it here to our special TouchTomorrow virtual bulletin board!
