Question
a teacher assigns the following experiment to a class. draw an outline of a birds feather, and color one half of the outline with a thick coat of wax from a wax crayon. leave the other half uncolored. next, sprinkle a few drops of water on both halves of the feather. you will observe that the water soaks into the plain paper. the waxy coat, however, allows the paper to remain dry. water forms tiny beads on top of the wax instead of soaking through it. water is a polar molecule, meaning it has a positive and negative end. the polarity allows multiple hydrogen bonds to form among adjacent water molecules. the hydrogen bonds attract water molecules to one another (adhesive property), and account for the ability of water molecules to adhere, or stick together, such as forming beads. water is a non - polar molecule, meaning it has no positive or negative end. the non - polarity allows no hydrogen bonds to form among adjacent water molecules. the hydrogen bonds repel water molecules from one another, and account for the ability of water molecules to cohere, or stick to other substances(cohesive property), such as traveling up a capillary tube or straw.
Water is a polar molecule. Its polarity allows hydrogen - bonds to form among adjacent water molecules. These hydrogen - bonds cause water molecules to attract each other (cohesive property), leading to the formation of beads. Wax is non - polar and water does not interact well with it, so it beads up on wax instead of soaking through.

The first option which states "Water is a polar molecule, meaning it has a positive and negative end. The polarity allows multiple hydrogen bonds to form among adjacent water molecules. The hydrogen bonds attract water molecules to one another (adhesive property), and account for the ability of water molecules to adhere, or stick together, such as forming beads." (Note: The term in the option should be cohesive property instead of adhesive property for water - water interaction, but it is still the correct description of water's nature compared to the wrong non - polar description in the second option).
