I'm excited to say that this will be the first installment of the weekly reporter for Earth and Environmental Science. Last year it seemed that there was such a battle to get reports. This year, first time out, every student wrote up their review. So, this will be a long post, but persevere, there is some good stuff in there.
As you will see, the topic of the week was weathering and erosion. Concepts that seem simple, but are responsible for so much of the shape of our earth. Without them, no Grand Canyon, no Yosemite Valley, no Mississippi Delta. Landforms as epic as these would seem to have been caused by some catastrophic force. They were, however, shaped over eons by forces as slight as the trickle of a stream or the hint of a breeze. Kind of incredible when you think about it.
So, I shall now get out of the way. This week we have contributions Lauren Moore, Wallaadah Bingham, Myles Graham, and Te'azsa Dash. Presently I am still waiting for a couple of the reports. Rest assured they are on their way and this post will soon be updated.
This week in Earth an Environmental Science we did various things. We learned to differentiate between igneous, sedimentary and metamorphic rock and related the rock cycle to the formation of each type of rock. We became able to distinguish between weathering and erosion and identify the variables that affect the rate of weathering. We analyzed the impact of living and nonliving things on the process of weathering and erosion, we also described the relationship of gravity to all agents of erosion. On Thursday we did a lot of things, we described how soil forms, explained the relationship between the organic and inorganic components of soil, identified soil characteristics, and recognized soil layers in a soil profile. On Friday we compared and contrast erosion by water wind and ice and also identified geographic features formed by erosion and deposition. We showed we had successfully learned the process and result of different types of erosion by creating a prezi that is due monday. This week in Earth an Environmental science was jammed pack with information we need to know for up coming test and assignments. Hopefully everyone in this class understood the information to achieve success now and later in the class.
This week in science we learned about erosion. Erosion is the process by which the surface of the Earth gets worn down. We also learned the difference between chemical weathering and physical weathering. Chemical weathering is the process of breaking down rock AND changing its chemical makeup. Physical weathering is just breaking down rock into small peices. It has the same chemical makeup at the end. it just has a different size or shape. We did a lab about identifying rocks; which helped us gain a better understanding of of how real experts narrow down and identify rocks. Overall it was a good week in class.
Throughout this week we have learned about many things in Mr. Kite’s class. On Monday August 27, 2012 we took notes on blood diamonds and real diamonds. We learned how real diamonds formed and what blood diamonds were. On August 28, 2012 we learned about the difference between weathering and erosion. We also learned about different types of weathering. On August 29, 2012 we took notes on weathering and erosion some more. We went into dept about the differences between weathering and erosion. On August 30, 2012 we found out how soil forms and the relationship between organic and inorganic components of soil. The different types of layers of soil are ground soil, top soil, subsoil, and bedrock. Finally on Friday August 31, 2012 we learned the definition of the word deposition.
