Checkerboard Chromatography

In this Activity, column chromatography separations are simulated using a grid, colored paper squares, and a six-sided die. Students observe the effects of changing flow rate, column length, and mobile phase composition. As squares come off the grid, the separation (or lack thereof) of the colors is noticeable.
