Over this whole year I have learned so much in Eighth Grade. I enjoyed all the labs. Especially the seismic safe building. In the same time period I also made a song, which was a parody to All About That Bass. My least favorite project was the hot air ballon because it was very hard trying to get our balloon to float, and to help, the type of launcher we were planning on using broke. I also enjoyed our trip to stone lab. It helped that we were by water and away from huron, because I mean, who wants to have a field trip in Huron? At stone lab we went fishing for zebra mussels, dissected fish, and got to hold snakes and frogs. I didn't like how long it took to get there, and I also didn't enjoy when we went out on the boat and took samples of algae. One of my teams greatest successes was the lunar lander. In which we took materials to make a model rocket ship, (and we were in a budget cut) we got our lander to launch perfectly and it landed and the Lego man stayed alive. One of my teams biggest failures was our egg drop. Our device landed but then with the force applied the egg shot out and broke.. I also liked all the songs we listened to.. I still have party rock anthem in my head! Also, over this year we have learned so much, from earthquakes to continental drift, and sea-floor spreading to genetic disease. My favorite part of the whole year was probably watching all the hot air balloons and watching them catch on fire. My least favorite was preparing for the Paarc test and those review sessions at the beginning of the period. My favorite homework assignments were either the current events or the flip books. The current events because I got to explore what was happening in science today! And I liked the flip books because I got to study and create pictures to remember the words easier.

The study of genetics applies to myself greatly. First, it applies to me because I am a female and have two x chromosomes. My mother gave me an x and my father gave me an x. If my father would have given me a Y chromosome I would be a boy. Also genetics control my traits and characteristics. Traits are controlled by single genes with two alleles. For example, ear lobes, I would have either free ear lobes ( dominant ) or attached earlobes ( recessive ). Or I could have single genes with multiple alleles, such as blood type. I could have three or more forms or a gene, but can only carry two. Lastly, I could have many genes that act together, like for height or skin. Without the proper environment it could alter your traits.
Many diseases can happen because of genetics. For example, color blindness is carried on sex-linked genes. Genetic disorders are caused by mutations in the DNA can cause changes in over all number of chromosomes. Types of these are Cystic Fibrosis, Sickle Cell Anemia, Hemophilia, and Down syndrome. I do not know any one with Cystic Fibrosis, which is a good thing because when you have this you have thick mucus in your lungs and intestines. This disorder was caused when 3 bases of your DNA molecule are removed. I also do not know anyone with Sickle Cell Anemia, which affects the blood cells allele is codominant with a normal allele. Although I do know people with hemophilia, which is when the blood clotts, which could into blockage. I also know someone with Down syndrome, which is when a person has mental and physical difficulties. This happens when there is an extra copy of chromosome 21.
In this chapter I was interested in cloning, which is when you take the nucleus out of a cell to produce a new animal, or species. It is amazing that you can produce the same, exact genes... I could get so much done with two people! Although I was not interested in genetic engineering, which is taking genes from one organism transferred into the DNA of another organism. I personally, think that is boring.
So much can still happen in the genetic field. We use genetics to assist with crime solving, and the genome project. Also gene therapy in the future. So much has already happened and I can't wait to see what the future holds.

I know a good amount of content on these next chapters. I known about recessive and dominant alleles. I am also very familiar with the Punnett Square. I am familiar with modern genetics and reproduction. Although I know a good amount, I do not know some things, such as I do not know who's Gregor Mendal. I am very interested to learn about DNA and how it codes. Also, how if one little stem is wrong a whole species could be eventually created. I also think genetic disorders and interesting on how they happen and occur ( I don't like how it happens to people, just how the process works. I look forward to learning more in these next chapters.

This map shows the overview of a river. It shows that the erosion formed valleys and water filled in, large in some areas, and small areas in others. This river has a lot of curves and is mostly a very narrow river.

The higher the slope gradient causes more erosion then the lower slope gradient. The absence of vegetation causes more erosion because the vegetation holds the soil together, so the more vegetation the less erosion. The higher the rain intensity causes more erosion than low erosion.
The worst situation would be having a 30 degree slope, no vegetation, and high rain intensity. This situation causes very high erosion. The best situation would be a 10 degree slope, vegetation, and low rain intensity. This situation causes very little erosion.

We have covered a lot of exciting information over the fist quarter and the beginning of the second. In class we did lots of design challenges starting with the marshmallow tower, in which we had little resources to build the tallest free-standing tower with spaghetti. This allowed us to use our imagination and work well with our group. We also made a lunar lander, and a seismic-safe building, which I learned a lot about thanks to the lab and my song! We learned about all the waves including the primary babes, the secondary waves, and the surface waves. Another big topic we hit was earthquake safety, in whichever learned how to build with proof by putting in insulators, sheer walls, cross braces, steel frames, dampers, and rubber layers. We also went through the Geological Time periods and made a poster and also drew the time periods on the street with chalk. We learned that there was many mass extinctions and we found this information by using the earth viewer app. I learned that there was a lot of life before us and how cool the extinct animals are. We also covered a lot of information regarding plate tectonics, convection currents, and earthquakes which I enjoyed. So far, science has been a success.
Even though the projects were fun, some of them I didn't find very interesting. Such as the lunar landers, I didn't find that project very interesting and don't think it would ever relate to my field later in life. I just really didn't see the point in that project. When subjects don't interest me I often forget them. For example, I remember building the lunar lander and dropping them, but I don't remember how and what materials we used. I also didn't like the ice core samples and law of superposition because I didn't find this topic interesting.
Now most of the projects I did find very interesting. Such as Stone lab, I loved dissecting the fish there especially the eyes because I want to be an eye doctor someday and the eye is my favorite part of the body. Also at stone lab I loved looking at the snakes and turtles and holding them was and excitement. I liked this because I also want to be a marine biologist because I love interacting with animals. To remember the subjects I either made a song... Or an analogy to my life. For example, I took continental drift and said that the continents move as they get older and time passes, like our groups of friends move away from each other as time passes. Science has been a fun year already and I can't wait for more interesting projects.
