Chromatography Experiment Concepts

The video tutorial guides kids through a chromatography experiment. It begins with an introduction and safety reminder, followed by a list of materials needed. The teacher then explains how to prepare the coffee filter and set up the experiment. Finally, viewers are instructed on how to observe the separation of colors, demonstrating the principle of chromatography.
