Water Molecules
Water molecules are small and highly polar. Their polar nature gives water its unusual properties. On a microscopic level, water is a network of these polar molecules linked together by hydrogen bonds.
Note: Water is perhaps the most common but important substance on the Earth. It is, however, very difficult to understand and model. It is essentially wrong to model water in two-dimension, which apparently misses some of the most important features of water structure. Nevertheless, we still feel that it may be helpful to young students even if the model is not entirely correct.

<b><font size="2">Key concepts</font></b><font size="2">: Water is
essential to life. Our cells are largely water, being surrounded in water
and using water to transport essential dissolved materials. Every cell can
be modeled as an aquatic solution of inorganic and organic compounds
separated from the outside world by a thin membrane. This membrane
regulates the flow of water and dissolved materials in and out of the
cell. </font>
