Walking Magic
Young scholars conduct experiment with water striders by placing the insect in two different solutions and discuss their observations. They discover that weight and surface area are important factors in their experiment.
Curated OER
Water Wonders
Students experiment with the cohesion of water molecules. In this surface tension instructional activity, students estimate how many drops of water a full glass can take before overflowing. They watch a video that explains water molecules.
