The Art & Science of Paper Marbling
Paper Marbling & Surface Tension
According to Wikipedia, surface tension is a property of the surface of a liquid that allows it to resist an external force. This property is caused by the cohesion of similar molecules and is responsible for many of the behaviors of liquids. One example of this is an insect that appears to walk upon the surface of the water, rather than sink.
Paper marbling works because the particles or substances used for the color are not heavy enough to break the surface tension of the water. The chalk dust floats because it is lighter.
7th Grade Science TEKS
Scientific investigation and reasoning.
(i) To develop a rich knowledge of science and the natural world, students must become familiar with different modes of scientific inquiry, rules of evidence, ways of formulating questions, ways of proposing explanations, and the diverse ways scientists study the natural world and propose explanations based on evidence derived from their work.
