This week, students explored the chemistry of water, by looking at properties like: Adhesion, Cohesion, Surface tension, and Capillary action. During the Walking Water experiment, students developed their understanding of the scientific method by designing their own fair test to study the factors that affect water's ability for capillary action. Students manipulated variables such as: the temperature of water, the type of paper towel, the position of the beakers relative to each other, and the distance between the beakers. Students also studied surface tension and the cohesive property of water molecules through the Drops on a Penny demonstration. Students were amazed to find out that approximately 30 drops of water could fit on a penny before the water spills over!
