What food dyes are in your candy? Is black ink really black? What gives fall leaves their color? These are all questions that you can investigate using paper chromatography – a technique that can separate mixtures into their individual components. This video explains how paper chromatography works, walks you through each step of a paper chromatography experiment, and provides tips and tricks for troubleshooting. We also introduce a couple of fun science projects that you can do using paper chromatography. You can find written instructions for these projects on our website at https://www.sciencebuddies.org/science-fair-projects/science-projects?s=paper%20chromatography.
Science Buddies also hosts a library of instructions for over 1,500 other hands-on science projects, lesson plans, and fun activities for K-12 parents, students, and teachers! Visit us at http://www.sciencebuddies.org to learn more.
