Markers are mixtures of many different dyes that can be separated using water and filter paper. Chromatography is a lab technique used to separate mixtures - when you use markers, the results are beautiful! We especially liked the black marker - it showed the best separation and revealed at least 5 different colored dyes. Before I became a science teacher, I was a biochemist at a pharmaceutical company. I told my students how I used to use thin layer chromatography to separate protein mixtures. Even though we were using markers - they were still so excited about using a technique that scientists really use in labs! I love their enthusiasm!

Holiday Lights Chromatography
My 7th and 4th graders worked together on a fun holiday science experiment last week - holiday lights chromatography! Using the chromatography lab technique, we created Christmas, Hanukah, and Kwanzaa lights:
Wishing you a blessed holiday season!
