Upon completion of this unit the student will be able to:

1.   describe the structure and geometry of a water molecule, and explain what 
      properties emerge as a result of this structure. 
2.   explain the relationship between the polar nature of water and its ability to form
        hydrogen bonds. 
3.   list six characteristics of water that are emergent properties resulting from 
      hydrogen bonding and polar covalent bonding and explain how these properties relate 
      to these concepts. 
4.   describe the biological significance of the cohesiveness of water. 
5.   distinguish between heat and temperature. 
6.   explain how water's high specific heat, high heat of vaporization, and 
      expansion upon freezing affect both aquatic and terrestrial ecosystems. 
7.   distinguish among a solute, a solvent, and a solution. 
8.   explain how the polarity of the water molecule makes it a versatile solvent. 
9.   distinguish between hydrophilic and hydrophobic substances. 
10. understand that a mole is a unit of substance concentration.
11. discuss the basic causes of global warming, acid precipitation, and ozone depletion
      and state three negative consequences for the environment caused by each.
