Weekly Blog 11/30 - 12/7


Citation: Soil Erosion
EasyBib Citation: N.p., n.d. Web. 06 Dec. 2015.
Summary: During this week, I learned that soil erosion is a naturally occurring process that affects all land forms. In agriculture, soil erosion refers to the wearing away of a field's topsoil by the natural physical forces of water and wind or through forces associated with farming activities such as tillage. Soil covers much of the land on Earth. It is made up of minerals, rock, sand, clay, silt, air, water, and organic material (matter from dead plants and animals).

SP8: Another thing we did this week was fill out a resource sheet (Research Sheet,) and answered questions such as, "What is soil?" Or "How is soil formed?" I learned really interesting facts, for example, I never knew that the soil profile was so important. "The soil profile is one of the most important concepts in soil science. It is a key to understanding the processes that have taken in soil development and is the means of determining the types of soil that occur and is the basis for their classification." I also didn't know that there were different types of soil, "There are three main types of soil—clay, sandy, and loamy. There are also other types of soil, depending on the type of underlying rock and the climate and vegetation. Loams are a mixture of clay, sand, and silt, and are more fertile than other soils. Acidic peaty soils are made up of rotting plants."

The Circulatory (Cardiovascular) System

Image
The Structure & Function: What is the function of the circulatory system?   The job of the circulatory   system works on circulating blood, lymph, nutrients, oxygen, other gasses, and hormones throughout the body, hence the name circulatory system. The circulatory system also balances temperature and pH balance while protecting the body from diseases. The circulatory system consists of the heart, blood vessels, blood, lymph, and the lymphatic glands & vessels. https://s3.amazonaws.com/classconnection/128/flashcards/8043128/png/insideheart1328771781022-14DEA48509547B9E19F.png What are the names and functions of the major organs in the circulatory system?  The names & functions of the major organs in the circulatory system are... Heart (cardiovascular): The heart is an organ that pumps blood through the body, providing oxygen & nutrients to the tissues (such as muscles). The heart also works on removing carbon dioxide and other unwanted wastes (whi

The Renal (Excretory, Urinary) System

Image
The Structure & Function:  What is the function of the renal system? The function of the renal system is the eradication of wastes manufactured by homeostasis (this word comes from two combined words in Greek: "homeo" meaning similar, & "stasis" meaning stable). The organs that are used in this process are the lungs, the liver, & the kidneys. What are names & functions of the major organs in the renal system? The names & functions of the major organs in the renal system are... Kidneys: the kidneys are organs that receive the waste from the body. The kidneys then percolate things from the waste, such as salt, urea, & excess water which is disposed from the body as urine. Skin: The skin executes its function through sweat glands. Sweat is used to cool us off as well as to get rid of unwanted oils, salt, water, and other gratuitous elements that ooze from small pores in the skin. Lungs: The lungs, an important organ in both th

10/24 Interdependence of Organisms

Image
              Interdependence of Organisms The interdependence of organisms is when organisms depend on each other for food to survive. Their whole reason to survival is so that they can live long enough to reproduce.  Backward Looking - Reflection: If an animal disappears from the rainforest then the animal who depends on this dying species for it's survival will also die due to lack of food. And so on and so on. Also it will affect the animal/plant that it does eat, meaning if the humming bird disappears from the rainforest or other biomes it will affect flowers or other plants, meaning they will over populate or under populate and that biome/rainforest will not have a healthy balances of plants and animals. Inward Looking - Reflection: I liked the work that I did this week because I could understand all the animals and the food chains/webs. I also liked it because of the fun activities that we did.I liked it because instead of using everyday textbooks, we get to google thi
