What colors are used in marker ink? (Day One, cont.)

This experiment was to determine what colors marker ink
is made out of. Chromatography is the process of separating
colors or pigments.

1) The kids colored the end of a coffee filter strip.
2) We placed it into bottles and added a bit of water to the bottom
3) We watched as the colors moved up and separated out

I got this idea from http://www.education.com/activity/article/Color_Science_kindergarten/
