The Mysterious Case of Bob Bacon

Our AP Biology class recently dissected fetal pigs as a way to interactively learn about the systems of the body. After doing so, we split up into groups of five to create a CSI mystery on how one of the pigs died. We created a story line, made up interactive clues, and set up a presentation where the class went to each of the stations to find the clues and attempt to figure out who killed the pig, how, and what body system was affected.

I worked with Amanda, Bharathi, Abi, and Jen S. Our system was the immune system, and we called our dead pig Bob Bacon. We set up his death as a murder mystery, starting off with a Breaking News TV Clip explaining that scientist Bob Bacon has died, and that the police had five possible suspects – all of which were his neighbors. The class was then asked to help out with investigations by visiting each of the “homes” of these suspects and determining who could be guilty based on the timeline, Bob’s medical record, and outside information. After spending about 7 minutes at each table, we reconvened as a class and asked everyone to collaborate and guess who the murderer may have been. We then released two more Breaking News Forecasts, which led the class to conclude that one of the scientists was responsible for giving Bob Bacon HIV 10 years ago, and that it was actually Bob’s cat who killed Bob by transmitting a disease. This disease, called toxoplasmosis, was able to kill Bob because his immune system was weakened from the HIV, which had eventually turned into AIDS. Here is our intro video which set up the scene for the project!

This was definitely one of the hardest projects I have ever had to do. The fact that it was a group project, even though I love all the members of our class, made it that much more difficult. Unfortunately, I was sick during most of the time that we got to work on this project during class, so our group was forced to utilize social media in order to communicate. Even with that disadvantage, I would say that we still did a great job! I enjoyed the creativity allowed through this project. I was able to throw in a lot of special touches and puns (such as the pigs name – ex. Connor Mc. Snorts) which delighted me and (hopefully) amused everyone else. It was interesting that we had to make some sort of wild connection that was so abstract that the class would most likely not be able to guess it at first, and THEN have to actually make them guess it within the time period. I am disappointed that I was not able to see the other groups’ projects (I hate being sick!) but I can only imagine that they were fantastic!

Cri du Chat Symposium

For the end of our first semester, we were assigned a symposium to research and make a presentation on a genetically-linked disease. My parter, Abi Grassler, and I chose Cri du Chat as our genetic syndrome. Cri du Chat is a syndrome resulted form a deleted portion of the 5P chromosome, resulting in mental retardation, speech impairment, and most distinctly a cry that sounds like the cry of a cat.

Making Meiosis Move

I collaborated with Abi Grassler to create a moving project that demonstrates the steps of meiosis in gamete cells. We used craft supplies – mainly Pipe Cleaners – to symbolize various organelles and depict the changes made and steps taken during meiosis. We then took pictures on an IPad, and used the Stop Motion application to string these pictures together in a motion film. You can view this video below:

Meiosis is a form of sexual reproduction and cell division. Unlike mitosis, which creates clones of the parent cell, meiosis creates genetic diversity – especially through crossing over, which occurs during Prophase I. Meiosis is similar to mitosis in that the cell goes through similar phases in both processes. However, meiosis goes through two divisions, producing four daughter cells, as opposed to mitosis which divides only once and produces two.

While Abi and I enjoyed using Stop Motion and taking pictures to create an animation of meiosis, using the craft supplies was challenging. Both Abi and I were originally unclear about the general process of meiosis, and we found that this confusion (on top of the struggle of using Pipe Cleaners and the time crunch) resulted in a lot of difficulties. However we did our best, and we are both really happy with the outcome of our project!
