Image: I took this picture on my phone. Summary Briefly explain the project. Tell us what you learned, not what you did. One specific thing that I learned about was what was a carbon footprint. I had never heard that term before, but know I know what it is , how we reduced it, and why ours was reduced. A carbon footprint is how much carbon is produced by transporting an ite m from one place to another. All of our materials are manufactured inside the U.S.A., so it couldn't travel by ship and it would probably travel by train because all the products are in the same country, but not state. Freight trains emit less carbon dioxide because they can travel about 400 miles on a gallon of diesel while a truck would only travel around 150 miles on a gallon of diesel. Since a train consumes less gas than a truck while traveling the same distance the train would generate less carbon dioxide. Reducing your carbon footprint help...

From this I learned a few key things to remember: Soil is composed of organic matter, pieces of broken rock, and minerals It is very difficult to identify different types of soil since the mix with other soils and move. Soil is very valuable even though we don't acknowledge it. We depend on soil for food, clothing, to hold buildings steady, and much more. Soil is eroded by water most of the time. Soil loss can be prevented by planting trees and other plants because the roots help to hold the soil in one place. With the substitute we worked on differentiating examples weathering, erosion, and deposition. Deposition is when soil and pieces of rock are added to a land form or landmass. After that, we were introduced to what are carbon footprint is and how it will be a part of our charity fair projects. First we had to determine w...

Weathering is the breaking up of rocks due to exposure to the atmosphere and erosion is when weathered material is moved from one place to another. If it is weathering the material is loosened but is not moved or carried away, whereas erosion is when the material is moved away by water, wind, ice, and waves. Weathering comes in two different forms, mechanical weathering and chemical weathering. Chemical weathering is when at least some of the minerals from the rock are converted into different substances. Mechanical weathering is when rocks physically break down into pieces without the chemical makeup of the rock changing. We looked outside our classroom to find ways the weathering and erosion are taking place and to my surprise there were so many examples. One example of weathering is th...
