water and the cool stuff it does

When I first learned that we were going to be learning about water I wondered why water it doesn't matter in biology?  Then the second question that came to my head was how does it stick together the way it does?  The lab we did just added to that interest.  I couldn't wait to figure out how it worked.  Then after I watched the video I understood how it worked.  The force that holds the water together is cohesion.  Then I thought, how does it stick to the string.  The answer to that was that was adhesion, that's when the water molecules are attracted to molecules in other things like the vein of a tree.  As I watched these videos I learned many different things that interested me.  The thing that stuck out to me the most was how the water stores energy from the sun that it catches in the day and makes the air cooler.  Then releases it into the air in the night to make the air warmer, making it a good temperature for us all day long.  Another thing that interested me was surface tension.  By definition it is the energy needed to increase the surface area of a liquid by a given amount.  This is the force on the top of water that lets things stay on top of it.  I wonder if this is how boats stay on top of the water?  On top of this stuff I also learned other things about water.  Most of these things I already knew from chemistry but it was a review of them.  I won't bore you with the definitions of them but the other items were hydrogen bond, hydrophilic, hydrophobic, polar covalent bond, and solvent.  These things deal a lot with the physical and chemical properties of water and makes water what it is.  For example the way that water bonds makes it have surface tension.  From this lesson I have learned that water is a very unique molecule and without it life would not exist and that is why it is important to biology.
