Summary: This week we started a new unit on ocean currents, in which we will learn how they relate us and the environment.To introduce the topic we watched a Bill Nye video to explain the basics on ocean currents. Wind and salt are the main cause of ocean currents. An ocean current is a stream or river of water flowing through the ocean. Since salt water is heavier than non salty water is pushes the non salty water away making an ocean current. The wind blowing on or with the water moves it creating an ocean current, as well. Another thing I learned was that water in the northern hemisphere flows clockwise while the water in the southern hemisphere flows counter clockwise. It does this because the sun is heats up the equator which makes the water molecules drift apart. Then, they weigh less, so the cold water from the North or South Pole pushes the warm water upwards. The water travels clockwise in the northern hemisphere and counter clockwise in the southern, but if the earth did not spin and if there were no continents it would flow from the equator to either pole.In addition, an experiment conducted in the video proved that salt water has a higher density than fresh water. When it has a higher density it means it has more stuff in the same space or it is compact. Water life, such as fish, depend on ocean currents for food, suitable climate, and transportation. After that, We studied the globe, especially longitude and latitude. We did an activity looking all around the world including land an oceans. In this activity I really noticed the comparison of land to ocean. When we traced the route to travel as much as possible only touching oceans, we saw that you can go through all the oceans.Finishing the week off we did a poster on the to compare humans and the Earth. Creating the poster really showed me that humans and the Earth have a lot of similarities. For instance, humans and the Earthier made up mostly of water. This week I learned about ocean currents and Earth.
S&EP-Using Models: This week we used models of the Earth on many questions and just to observe in general. Just by looking at the model you could see that there is more water than land, about 71% of the Earth's surface is water. Using the model globe we did a mini experiment to see if there really is more water than land. My partner and I passed the globe back and forth ten times. Each time you caught the ball, wherever your right index finger would point, you would record the place, the longitude, and the latitude. Six out of ten landed on oceans while the other four landed on land. We thought that this was not a very accurate way to test it, although it may be fun. We thought this because your finger may land on land because of the way your partner is throwing the ball. Another thing is you can see there is more water than land just by looking at the globe. Esch group will also get a different result, but there is only one answer or amount of water. Another way we used models or drawing is when we had to look at the globe and draw out a scene which contained the most land and one that contained the most water. For land, our picture showed Africa, Europe, and Asia and for the water it showed the Pacific Ocean with some of Asia and North America showing in the corners. In the drawings you could clearly see how much land or water there was, especially if you compared both drawings. Using the drawings and globe helped me comprehend the water to land ratio.
XXC-Cause and Effect: While learning about ocean currents I realized there are many cause and effect relationships. For example, salt and wind cause ocean currents. Salt does this because it is heavier than regular water. It pushes the regular water and you have an ocean current. Ocean currents can be formed by wind, as well. The wind moves the water in a certain direction. This cause is salt and wind and the effect is an ocean current. As well as that, the water in the northern and southern hemisphere turn in different directions mainly because of the North and South Pole, the sun., the spinning of Earth and the continents. The sun heats up water at the equator which makes the lighter, so the cold water pushes them. If there were no continents and the Earth wasn't spinning, the water would travel to either pole. Since it does the water in the northern hemisphere travels clockwise and the water in the southern hemisphere travels counterclockwise. Not only that, ocean currents cause, or in this case allow, water life to move through the water, retrieve food, and have a suitable climate. From all of this I can see that ocean currents are very helpful to living things and why an ocean current is what it is. Another cause and effect relationship is why rivers and lakes aren't salty. The cause of this is rain water washes the salted other minerals from rocks and soil into lakes and rivers. The salt and other minerals move from the rivers and lakes into the nearest sea or ocean. This means that salt and other minerals get rinsed out of lakes and rivers.Throughout this week I have noticed and examined many cause and effect relationships.
Multiplier: This week I was a mutant, but to be more specific a creator because I volunteered to find answers to things my group and I didn't quite understand.
