The Water Race: Hydrophobic & Hydrophilic Surfaces (High School curriculum lesson)

This activity developed by NNIN explores how nanotechnology can be used to change the properties of a copper surface so that it either attracts or repels water. It is appropriate for middle school and high school students.

Nonpolar molecules that repel the water molecules are said to be hydrophobic; molecules forming ionic or a hydrogen bond with the water molecule are said to be hydrophilic. This property of water was important for the evolution of life. Hydrophobic interaction plays the most critical roles in the formation of the lipid bilayer of the cell membrane and the folding...
