Letter to a Biology Student

          Hi, my name is Elizabeth Kardach. I was 15 years old when I started this biology course. I went to Redwood Middle School previously. The subjects I was most interested in at the beginning of the year were my elective creative writing and English. My interests outside of school include piano, violin, drawing, painting, running, and video games. On the first day in this class, I expected a lot of hard work.
          I quickly picked up that Mr Orre's expectations for us were a lot higher than that of other teachers. The first things we were required to do when we walked into class were to take out our notebooks and planners, write down the homework, and start the Do-Now. Nothing more, nothing less. A typical class day involves reviewing the vodcast from last night with the vodcast recappers for a few minutes, and then with the entire class. Then the rest of the class is usually a lab, a blog post, or work time. The homework is daily and consists of a vodcast and CFU. The homework usually takes about 15-20 minutes, depends on how long the vodcast is. We don't get quizzes, but the tests are always very fair and if you study well, you'll do well. The notebook is the most crucial material to this class because we use them every single day. We write everything in our notebooks, and before every test we do a notebook check where we check our table of contents and vodcasts and get points if we have everything in order. The blog is also a very crucial part of class, because we make blog posts usually after every unit or lab. My favorite blog post is my first post on my 20-Time project because of the pictures I included on it. (http://lizziebio.blogspot.com/2017/02/catch-it-before-its-too-late-alzheimers.html). I felt I changed over the course of the year because of some of the presentations we got to do I feel a lot more confident in my public speaking.
          Some of Mr Orre's pet peeves are talking when he's talking, not paying attention, not cleaning up properly, not participating in mindfulness, not participating, not doing the CFU's, interrupting other students when they're talking, not doing the Do-Now, not having homework, not having your notebook ready, not doing the relate and review, etc. Getting a good grade on assignments usually relies on the amount of effort and sincerity you put in. Homework is incredibly important in receiving a good grade. If you don't do very well on tests, the homework can still help you pass. Getting good grades on tests simply requires a lot of studying and reviewing. Three mistakes I made this year was missing some second semester deadlines, since he doesn't accept late work second semester, not studying hard enough for some tests, and missing some unit reflection blog posts. I learned that all of these mistakes can really affect my grade so I took great caution after making them.
          Overall, I really enjoyed this class along with Mr Orre's teaching style. I liked it because it was fun and very informative and Mr Orre was a really nice and good teacher to have this year. I'm taking Chemistry next year because I want access to anatomy in my senior year.

Final 20-Time Post

         My final product for 20-time turned out the way I'd wanted it to, and I was satisfied with it. I created a powerpoint summing up Alzheimer's and what prevents it or causes it, and then I listed symptoms of Alzheimer's disease and symptoms of regular aging and compare/contrasted them. All in a single powerpoint. You can view it here: https://docs.google.com/presentation/d/17JjTVLahi1eA_7uQBRrQOUUcryRKux_lHGlLHv1kPT4/pub?start=false&loop=false&delayms=3000

          I researched a lot on this project and worked really hard on learning the differences between these two common ailments, but this project also took me a while to get started on. So overall, I think I'd give myself an A-. My very first blog post was my favorite, you can view it here http://lizziebio.blogspot.com/2017/02/catch-it-before-its-too-late-alzheimers.html

20 Time Reflection

          I chose to study Alzheimer's disease for my 20-Time project because I have a long line of family members who have had the disease, and I realized I never really fully understood it. My goal was to learn the difference between Alzheimer's and dementia or normal aging. My initial plan to achieve my goal was to just research subtle signs of Alzheimer's and normal aging and be able to recognize the differences clearly. It went pretty well I'd say because now I know how to slow the process of Alzheimer's or even prevent it as well as how it differs from normal aging. If I had the chance to do this project again, I'd probably create a fundraiser for the Alzheimer's association to raise more awareness. I've decided to share the prevention techniques I've learned with my heavily Alzheimer's prone family in an attempt to assist them if they are diagnosed in the future.

Pig Dissection

Pig Dissection

         At the beginning of the pig dissection, we were handed our freshly bathed pig and started out by doing what any normal group of teenage girls would do minutes before cutting into a squishy fetal pig; gave it a name. Jemima. Although Jemima was a dude, we thought the name was fitting, and thus, Jemima's reign began. We started by tying down his arms and legs underneath the dissection mat before we made cuts all the way around the belly button and down his sides near the rib cage. By then we were able to identify the liver, small intestine, large intestine, urinary tract/reproductive system, and diaphragm. We cut all the way up to the neck and found the esophagus, trachea, and the voice box. Over all, the pig dissection was really fun and educating. My group and I had a lot of fun filming our videos, you can watch them here.

Geographic Timeline Relfection

Geographic Timeline Reflection

    

    One of three major events that happened during Earth's history was the formation of Earth, when it was a planet entirely made of lava and constantly bombarded with comets and meteorites. Another major event that occurred was when the super-continent called Pangea formed, along with reptiles and other types of animals. A third major event was when a massive asteroid hit the Yucatan peninsula, and most dinosaurs went extinct, which is why they aren't around today.

    Earth's history dates back for forever, and we are only an incredibly tiny smudge compared to the rest of the periods. I was surprised by this because obviously it feels like we've been around forever but we really haven't.

    The impact we've had on Earth in such a short time is pretty frightening, considering that we have been able to damage and manipulate it in this time period. It really makes me wonder about what the future has in store for humans.

Prevention: Alzheimer's Blog Post #3

Alzheimer's: Prevention

         I've learned so much more since my last blog post about Alzheimer's disease and more importantly, how to prevent it. I will definitely include the six pillars of Alzheimer's prevention in my final project. One thing I've learned about myself throughout this project is that I actually work very well under stress or pressure or confusion. Or all of the above. Whenever I found myself in a pit during this project, I would stop and think about my next move before acting on it. I feel like that's helped me through my research a lot. I've only encountered a few setbacks revolving around confusion or what to do next for my project. I was able to get over them by taking breaks and stopping to think about my progress.
        The next step in my process is to begin my final product. I'm going to try and piece my entire differences list together within the next few weeks. The great thing about choosing Alzheimer's disease as my topic for my 20-time project is that now I know the differences between the actual disease and normal aging, I can tell whether or not I will have it once I'm older. Alzheimer's is genetic in my family, so it's something we need to be really aware of. I can apply the prevention techniques I've learned to my routine to help slow down the process if I ever find myself diagnosed.

            

Unit 8 Reflection

Unit 8 Reflection

          In this unit, we learned about artificial selection, natural selection, evolution, speciation, and the geographic timeline. We were taught the difference between artificial selection and natural selection, which to me, sounded as if it'd be nearly nonexistent, but as it turned out they were nearly two completely different types of selection. 

Artificial selection involves breeders picking out which animals to breed for which desired traits.

Natural selection occurs when a species is unable to adapt with the phenotypes it was born with, and thus, dies off.

                 We also learned what speciation was. Notice how I said we learned "what" it was and not "about" it. That's because I had absolutely no idea this term even existed before this unit. Apparently, speciation is the rise of two or more species from one existing species. I thought this was simply called evolution but apparently it's more specific than just that. Evolution is just the change in allele frequency over time.

          The geographic timeline is still pretty confusing to me, but I'm sure it won't be once we finish our group project of creating an actual timeline on it. 

   I think it'd be interesting to learn more about the dinosaur's downgraded evolution. I want to know how a giant velociraptor could eventually transform into a chicken after a couple billion years.

         As for the assertiveness, I'm still working on it. I'm not very good at being assertive because I often confuse assertiveness with aggression, and I obviously don't want to be aggressive. One thing I did was when the woman making my sandwich at Subway asked if I wanted my sandwich toasted or not I actually said no this time instead of just awkwardly agreeing to it. Baby steps.
