Hi everyone and welcome to the first blog post of the 3rd quarter!
Our requirements have changed a little bit, and the more detailed information can be found
here. The main change is that we have to do less comments; only one per every two weeks! The next one is due on Friday, February 4th.
Thursday's class
On Thursday we immediately started working on our "Genetics Relationships" projects. We had a sheet with directions and a rubric. The project was mainly about defining words and then explaining how they are related with genetics and each other. The words we had to define were: Almost everyone presented their project on Thursday;
Sophie, Noam and Ciprian:
Iva, Terez, and Vance (Iva missing):
Calvin, Bryce, and Antonia (Antonia missing):
and Gio and Reza (Reza missing):
Here is the song "It's Called Genetics" from "Bill Nye the Science Guy"'s show:
Our homework for Friday was to read pages 84-89, which was the section "Probability and Heredity".
Friday's Class
When we came to class, Val and Viktor (me) presented their "Genetics Relationships" project:
We started discussing Gregor Mendel (an Austrian monk who started studying heredity, and combined pea plants to get different combinations) and his work, and after that we discussed our homework and what "homo" and "hetero" mean. "Homo" means "the same" and "hetero" means "different". We also discussed people having three sex chromosomes, such as XXX or XXY. This often leads to Down Syndrome, which you can read more about here. Jamie Lee Curtis is a famous actress who has three sex chromosomes, as well as Lady GaGa. People who have this disorder are called hermaphrodites. After that, we started talking about Punnett squares. Here is what a Punnett square looks like.
Then, we worked on the Bikini Bottom Genetics sheet that we got from Ms. D, which we have to finish for Tuesday (but only the front page!) If you want to, you can do the back page as well.
That's all we did these two days; remember to check the
Science Moodle page for information about homework and other assignments.
The next scribe is Ciprian - good luck! :)

Vocabulary used in this scribe post:
Genetics: The scientific study of heredity.
Heredity: The passing of traits from parent to child.
Chromosomes: A combination of two identical chromatids and a centromere, holding DNA, found in the nucleus of the cell.
Sex chromosomes: The chromosomes "X" and "Y", used to determine your gender. Usually you have two sex chromosomes, XX if you're a girl, and XY if you're a boy. This is not the case if you are a hermaphrodite.
Punnett squares: Charts that show possible combinations of alleles passed on from parents.
