The Water Molecule
The Amazing Properties of Water
The properties of water make it one of the most remarkable substances on Earth. To understand the unique properties of water, you must first examine its molecular structure. Visit the United States Geological Survey's Water Science School to learn about how the special properties of this common molecule support life on Earth, and how water interacts with other types of molecules in the environment.
While viewing the USGS Water Science School, find the answers to the following questions:
- How many atoms are there in a water molecule?
- What property makes the water molecule attracted to other other molecules?
- Why is water considered a universal solvent?
- What property causes ice to float on top of water?
- Why are certain species of bugs able to stride across the surface of the water without sinking?
- How can you describe the heat capacity of water?
