Core Skills Analysis
Science
Rosalie watched water travel through a paper towel and carry washable marker colors with it. The activity showed how cohesion—the attraction between water molecules—and adhesion—the attraction between water and the paper towel’s fibers—helped the water move through the towel. Rosalie also saw that washable, water-soluble ink could dissolve in the moving water, while permanent marker ink was included for comparison. The experiment connected this movement to how plants draw water upward through their roots toward their leaves and flowers.
Language Arts
Rosalie encountered scientific vocabulary through the activity, including cohesion, adhesion, and water-soluble. The demonstration gave Rosalie a concrete example to connect with the meanings of those terms: water molecules stuck to one another, water clung to paper towel fibers, and water carried dissolved washable ink. Rosalie could use the sequence of water moving through the towel to describe the experiment in order and explain what happened to the colors.
Tips
Tips Turn the demonstration into a mini investigation by inviting Rosalie to predict what might happen when different washable colors meet the water, then observe and describe the results. Make a simple diagram showing water traveling through paper towel fibers and label cohesion, adhesion, and dissolved ink. Extend the plant connection by looking closely at a flower or plant and tracing how water moves from roots toward leaves. Rosalie can finish by explaining the experiment aloud or writing a few sentences using the new science words.
