Today we started our review for the quiz. We went on our Discovery Education Techbook to do some assignments. I am quite confident about the quiz. I got a 100% on the first assessment and 85% on the second. The reason I did not do as well on the second one was because I wasn't paying attention and didn't read carefully. I think I can do really well on this quiz and that it will not be too hard. After the assessments, we put flowers in our soil erosion experiment. I am not going to explain this lab yet because I have no idea what it is about.

Today we took the our Unit 6 quiz. I think I did well on it, but I might not get a 100 %. It was about the different types of erosion and weathering. It was also about the different things that can affect these processes. I also now know what the lab that I talked about yesterday is. We will be comparing the erosion that occurs in three different scenarios. We will be seeing how much better soil stays in place with plants in it as opposed to loose soil or soil with large particles on top. It is hard to explain this so I will show a picture.
The eroded soil should go into the bottle halves below

Today we reviewed the quiz. I didn't do as well as I had hoped, but I still got an A. I missed two multiple choice questions and each could have been prevented. I read the problems too quickly and made mistakes. On one I thought it said erosion, but it really said weathering. I need to make sure to check my work and to work carefully and thoroughly. We also saw how much erosion was happening in the only soil bottle and how little was occurring in the plant bottles. I didn't think there would be such a large difference.

Today was fun. We took part in a really cool and yummy soil layer experiment. We put delicious foods in layers in a cup to represent the layers of the soil. The foods included animal crackers, pudding, cake, and whipped cream. Soil has multiple layers. The top layer or O horizon contains humus, the most fertile soil. The next layer, the A horizon is the top soil which is also quite fertile. Next comes the E horizon which doesn't have many nutrients. All of its nutrients have made their way to the next layer or the B horizon. This is the sub soil. It is still a bit fertile. Next comes the C horizon it is not fertile and contains large chunks of bedrock. Lastly comes the R horizon, the bedrock.

No Class!
Summary: This week was a good week as it reminded me to remember to check my work after taking a quiz. I had recently stopped doing that so now I know what happens. I need to work on this.
