The Kindergarten children have been so interested in color mixing over the past few weeks. Today, we did a chromotography experiment to explore colors in another way. Chromotography is the process of separating different components of a mixture. In our experiment, we were separating colors. The children drew a line of the color orange, green, purple, and black on individual strips of paper towels. They then placed the bottom of the paper towel in a shallow amount of water. When the paper towel is dipped in water, the water begins to absorb into the paper towel and travels up carrying the colors with it. It causes the colors to separate or split and different colors get carried along faster and further then others. As we dipped the paper towel with the orange line into the water, the children were immediately filled with excitement as they watched the yellow and red colors travel. We can't wait to see what our paper towels look like when we come back next Friday!
