Surface water

Period 4 Biology Surface Tension of Water I. Objective: How does soap affect the surface tension of water? II. Background: The surface tension of water is due to cohesion forces that allow water to stick to its same molecules. In a liquid, such as water, molecules are strongly attracted by each other causing a phenomenon called surface tension of water. Surface tension could be defined as the force that implies a liquid to resist external forces produced by cohesive forces of the molecules in water. III. Hypothesis: If we put soapy water on the penny, then the penny will not hold the same amount of drops of soapy water as the penny with tap water because the soapy water is will not stick to itself. IV. A.…

When the mound of water has reached the highest point is called high tide. On the side of the earth opposite the moon, the centrifugal force caused by the earth's rotation produces another mound of water and high tide on the opposite side of the earth. Somewhere in between these two high tides are two flat areas on the surface of the ocean, these are called low tides.
