Final Assignment

During the past few months I learned so much about seventy percent of the planet we all live on, the ocean. The physics of the Ocean is so fascinating to learn about and experiment with. We did a various amount of labs where we learned about the tides, the temperatures, the salinity, the density, the minerals found on the ocean floor as well as washed up on the shoreline. There is so much living matter within the waters, and we hardly even know the half of it all. The difficulties of getting down physically on the ocean floor has become much easier because of the modern technology scientists are creating. One for example, they have a team set base down on the ocean floor for a while to run tests, and examine all natural living matter down there. We followed this movie selection, with an assignment where we created our own laboratory on the ocean floor, and we picked a species to study. We recently have studied the changes in water temperature based on the location around the equator and the poles. We learned Density is affected by temperature, as well as its salinity. Warmer water will have less of a salinity, and colder has more salinity. We had a lab where we used hydrometers to test out the density while we added various amounts of salt to the mixture of blue dye and water. While we added more salt to beaker it floated more than with just fresh water. The ocean life has sure brought a interest into my eyes, and i would love to learn even more about the topics of physics.

Build a Hydrometer

Conclusion and  Questions:

Salinity is expressed as the number of grams of dissolved salts in one kilogram of seawater. If you ass salt to a water solution the hydrometer will lower because there's more density in the water. The addition of salt on properties of water allows it to become more dense with all the minerals. Density is the degree of compactness of a substance. Temperature causes differences in salinity of water because high temperatures create a higher density, and a lower temperature will create a less dense space.

Its all Connected

  In class we learned a lot about wind patterns and currents. Wind patterns greatly influence the currents in Oceans. The reason is because the wind pushes up against the water and constantly pushes the waves in that direction. Because of this, water is constantly moving on the Earth. For instance, Water off the shore of Brazil is usually a lot colder because it is being pushed from up towards Alaska toward the equator. And water from the Equator is pushed either NE or it is pushed down south. It is warmer on the equator because of the angle the sun light hits it. It is stronger there than any other part of the globe. In 1992 many rubber ducks were abandoned in the ocean and scientists tracked where they ended up which totally helped scientists research water and wind patterns on the globe.  The wind comes from down towards the equator and either keeps going to the poles or it goes back into the Atlantic Ocean. The air from towards the equator brings a lot of moisture and heat. If a hurricane were to pick up a message in a bottle off the coast it could also affect where it would end up. The warm water coming from towards the equator brings dolphins/sharks and other tropical sealife and when the water goes back out towards the equator it probably picks up a lot of human waste which is unfortunate. I am happy that there is international law over what we throw out in the ocean, because if it were only local law, we would still be getting affected by the choices of a country across the globe. We should try and dispose waste in space instead of the ocean, because the oceans are limited but as far as we know space has literally infinite space.
