Summary
There are many rivers in the world. Sadly, a vast number of rivers are constantly being polluted. This is due to things like oils spills and littering. In the lower section of the Ob, people have been using the river as a place to dump oil. This has caused severe pollution in the river hurting the plants and animals that rely on the river for a habitat. Another commonality I found in many rivers is that they are often being used as a way to produce electricity. For example, people build hydro-electric dams among rivers. Though producing clean energy is a good thing, this can also cause erosion problems. Many different cultures rely on rivers for things like fertile land (peat soil), fish, and water. Because of this, protect rivers should be a priority of many. Not only do rivers provide resources for us, but they also help us economically. While I saw other river presentations, I noticed that many (if not all) of the rivers are or were in some point of time used for transporting goods or tourists of some sort.
SP8: Obtain, evaluate and communicate information
I communicated my findings about the cultural, economical, and environmental significance of Ob river when I presented my groups river documentary to the class. My river documentary was about the Ob river. I also showed others my groups map and model. I obtained information when I watched the presentations of the other groups. After each presentation, I had to write at least 3 facts about the river I just learned about in my notebook. Many of these rivers had several similarities. Like how I mentioned earlier that most of the rivers are being used as a transportation route.
Cross Cutting Concepts - Systems & System Models
The system I have identified is the Ob river system. The different parts of this system is the water, plants, and animals. The plants and animals depend on the water and each other for food and a home. Everything in the system works together to ensure that every part of the system is safe. A river is a system because it has many different things living in it. It even provides food and resources for people living around the system. This is one way the river system can connect to another system.
So, how does this river system connect and affected other systems? One way that river systems are connected to others systems are through tributaries. Because of tributaries, the water is able to spread to new places where a new system will be made. Different plant and animals will depend on this new system. The Ob river system has over 1900 tributaries, it is connected to over a thousand different rivers all around Russia. The Ob also produces fertile land. Fertile land is an essential part of our system. The human system, we need fertile land to grow food. This is how two systems can depend on each other for different things.
