Above Water: Buoyancy & Displacement
Read the Fine Print
Rating

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what the relationship is among surface tension, buoyancy, density and displacement; and how shape, size, and type of material affect an object's ability to remain buoyant. The introductory text discusses how heavy steel ships can float on bodies of water like rivers, bays and oceans.

Stuck on You: Adhesion
Read the Fine Print
Rating

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.
