Learners explore water adhesion and learn about why water molecules are more strongly attracted to some substances than others. In an investigation titled "Fabric Frenzy," learners use a magnifying glass to examine different fabrics and hypothesize whether each kind would be good for soaking up water. Learners then weigh the dry fabrics, predict how water will affect the weight of each sample, wet the samples, and weigh them again to see how much water they in fact absorb. Learners also examine other liquids and compare their adhesion to water adhesion.
