The Understanding of H2O

Yesterday and the day before we did experiments on water. A couple of experiments we did were seeing how many drops of water from a pipette we can hold on a penny. Another experiment we did was connecting a string to 2 beakers, one with water and one without, then trying to move the water from the full beaker to the empty one with a string. The group in our class that transferred the most water with the string used 16.9 ft of string.

Did you know that all living this are made up of 70% to 90% water? Water is a substance that has a high heat capacity. I learned a lot about how water is one of the only substances that expands when it freezes. This is because when the molecules of water, 2 hydrogen molecules and 1 oxygen molecule, freeze they are shaped weird so they have trouble sticking together. Water is a polar molecule. It lets hydrogen atoms collaborate within water atoms. This is how living things exist and can carry on cellular properties. Water is a very neutral molecule because it is made of an H+ atom and a OH- atom and a positive and a negative connect.
