This week has been one of my favorite weeks, because it was HEART week!! First off we got to watch a really cool BBC documentary series about surgery, specifically the heart, which was so interesting. I’m looking forward to watching the other episodes. Then of course the next couple of days we got to cut into a deer heart, and understand how all the little valves and arteries come together. I learned so much about the heart this week, and I find it so fascinating how structured the heart is, blood comes in one way and goes out another a specific way. Of course to finish off the week, and make things even better the mouse had her babies!! And a big thanks to Mrs. Cole’s husband for getting all those deer hearts for us!

Our week was kicked off by a quiz on inheritance, and then followed by a group project focusing on maintenance physiology, my group was given gas exchange. So for the next couple of days we worked together to figure out why gas exchange is so important and how it works in different organisms. I thought this project was really cool, in the end we had to squeeze all our information onto two pages (we used three), and share it with the class. I thought all the other groups did a really good job, and I learned a lot about different maintenance mechanisms.
This week we did a really cool lab focusing on different Drosophila (fruit fly) genetics. This was a virtual lab where we were able to pick out the traits of our fruit flies, and mate them. We were then able to see the following generations to figure out if the trait we picked was dominant, recessive, sex-linked or co-dominant. This was a super fun lab, and really helped me better understand all the different kinds of inheritance patterns.
This week we focused on understanding genetics, and some mutations that can happen by doing a giant cancer activity. In this activity we were all given cards with different kinds of cancer on them, and a description of the kind of gene and its location. We got together in groups and talked about similarities and differences we had. One of the big similarities, which I talk about in my previous post is that the more genes on a chromosome the more common that chromosome will be involved in a mutation. We also did a lot of practice this week with punnett squares, and chi-squares which has really helped me understand the statistical element of genetics. We also did an activity about crossing over, which just showed how much variation can be caused by the event of crossing over.
