Summary Ocean currents can bring bottles almost all around the world. We were given two locations and had to figure out how currents could bring the bottle from one area to the other. This familiarization included the temperature and salinity of specific currents. In my set of currents, there were two neutral currents and 1 cold current. I  also learned how the different currents interact with each other. This is a way that this bottle can get from Tasmania to Namibia if it takes the right currents.  Backward-Looking: How much did you know about the subject before we started? I actually new a lot about currents before we started this project. I was already very familiar with density which plays a key role in how the currents form/work. There were things that I never thought about before this such as how land masses affect how the currents move. Inward-Looking: How do you feel about this piece of work? What parts of it do you parti...

en.wikipedia.org Summary:  Oceans currents are a crucial part of the ocean environment. They are powered by wind circulation across the surface of the ocean. Ocean currents are created by density, salinity, temperature changes, and wind. Because of this, wind currents and ocean currents travel in the same general direction.   When two winds clash, they bounce back and then turn causing gyres. Ocean currents also create gyres (from the wind). This occurs along with the wind. The water hits land masses causing it to bounce back and form and travel in a circular shape. This means that if there were garbage it would just stay there for a long time. (GPGP)  Currents flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere.  SP2: Developing and Using Models: We used models to explain how different things contribute and affect the forming of currents, mainly ocean currents. We put two rocks in a small tub of water along with some ...
