Heart Week Reflection

How did you do on the work this week?

So this week was obviously pretty exciting as we go to both look at and cut into a real heart. The packet we did was pretty easy, and the lab it's self really helped me visualize how all the components of the heart come together and where each chamber sits in the heart. See the example heart attached to the other organs also was very helpful as we got to actually see how the heart sits among the other organs, and how it attaches to them. On the less exciting side we had the test this week which I felt pretty good about while taking but I wasn't super confident on a couple multiple choice questions that were a little tricky. The free response however I thought went really well and I am hoping I got a good grade overall.

What do you think you understood well?

After doing the heart dissection I think I understood how all the components of the heart worked together pretty well. It helped a lot being able to hold the heart in my hands and follow where the   de-oxygenated blood would come in and where the oxygenated blood would come out. On the test all of the hybrid crosses and anything to do with figuring out what genotypes different generations have, or with finding out what type of relationship is prevalent in a gene, I understand very well as that is what we spent a lot of time on in CP Bio.

What do you thin you need to improve on?

I think I need to improve on my understanding of meiosis. In CP Bio we did spend a ton of time on meiosis or mitosis so I don't remember much from that, so a lot of it was new information and I think I need to study it a little more.

What strategies will you use to improve?

Not only to improve on this, but also with the AP test rapidly approaching I am going to start reviewing all of the vodcasts and parts of the textbook with subjects I didn't understand well. I also have started doing practice tests online so hopefully that will help me stultify some subjects I need work on.

How does the work we are doing fit in with the overall narrative of the course?

The heart has to do with regulation which is very important in keeping organisms alive, making it important to biology. The heart dissection also gave us a glimpse into what a real life experience could be in a biological field which relates to showing us careers in biology.

Reflection for April 3

How did you do on the work this week?

I think I did well on the work this week, we finished up our work with the sticklebacks and did our group projects about different body systems. My group had gas exchange and I think we did well on explaining the details of the process, even though it was hard to put all the information necessary on the space allowed. 

What did you understand well?

I understood gas exchange the best (obviously), and think I also have a pretty good grip on the circulatory system and its relationship to the process of gas exchange. I have an alright grip on nutrition but think I need to study it a little more.

What do I need to improve on?

I think I need to study nutrition a little more, and focus on understanding all the processes of excretion better, and what vital roles it plays in the body. I also think I need to review this weeks vodcasts.

What strategies will you use to improve? 

I will use the fact sheets that each group made to study each process and I will re-watch the vodcasts to better understand those.  

How does the work we are doing fit into the narrative the course? 

This unit, regulation, has to do with the processes of the body and the things that make it possible for us to live. Without all these process working together our body would not function the way it needs to and we would not be able to live, this is obviously a huge part of biology.

Reflection for March 27

How did you do on the work for this week?

This week I think I did pretty well on the work, the virtual lab was easy and I liked being able to pick our own traits and try to figure out what kind of dominance we were dealing with. While it take me a minute to remember how to do crosses with X-linked traits, the crosses we did were pretty easy. We also started looking at the stickleback fish which I thought was really cool.

What do you think you understood well?

I think I understood how to figure out which kind of dominance or inheritance pattern we were looking at by the end of this activity. I also think I understood calculating probabilities of crosses well.

What do you think you could improve on?

I think I could improve on doing di-hybrid crosses, and on understanding the genetic side of what was happening with the stickleback fish. I imagine as we get further into the activity what happened with the stickleback fish will make more sense.

How does this fit into the narrative/ context of the course?

What we learned from the stickleback fish can potentially be seen in other species and has to do with the part of the class that deals with modern applications of biology. As far as the fly lab, it allowed us to not only veiw the procedures necessary for that type of experiment, but also to view different kinds of inheritance patterns, which are all very important in bio.

Reflection for March 24

How did you do on the work this week? 

I did okay on the work this week, I understood how to do chi-squared a lot better in this packet than in the last one, it is a lot more simple than I thought. I thought the packet with the pedigrees was pretty easy

What do you think you understood well?

I think I understand the pedigrees well, and basically everything in the packet we did. The punnet squared are really easy. I also understood the finding probabilities well, multiplying the probabilities of small punnet squares together, is much easier than making a giant one, especially when dealing with more than one gene.

Where do you think you can improve? 

I think I can improve on understanding chromosomes more and how gene crossing over works. I understand the general ideas of it but not the specifics.

How does the work we are doing fit into the overall narrative/ context of the course?

This week we did  a lot with genetics, which is obviously a big part of biology, and is a lot of our modern research.


Three thing you learned in this activity.

  • I learned that different cancers can have the same or very similar mutations yet be different in location, type, or severity. 
  • I also learned that different mutations can cause the same cancer. 
  • Some chromosomes can have multiple genes on it that cause cancer. 
Two Things That Surprised Me/ Interested Me 
  • I thought it was interesting how one chromosome can have so many genes that are known for causing cancer on it. I thought this was really weird and wondered why this is. 
  •  In sort of the flip side I thought it was interesting how so many different genes can cause the same cancer.  

One Question I Still Have

  • How is it different chromosomes can cause the same cancer? How does that work?
