Punnet squares are used in genetics. They are used to keep track of genotypes like Bb. I made a punnet square myself. It was about having a normal chin, which was dominant, and having a cleft chin. The genotype was CC,Cc, or cc. My results were that if I were to have children, that 75% of the children would have a normal chin. The genotype was Cc and Cc.

What I learned was how to use a punnet square and learning about genotypes and phenotypes. A genotype is a person's physical make up and a phenotype is their appearence. All people get their genotype from their mom and dad. They also get some of their looks.

In science, we made a DNA ornament. The DNA ornament was pretty fun. It was kind of hard to make because there were a lot of steps to do and I kept messing up. The DNA ornament uses wire and glass beads. The first step was to put some yellow beads and white beads in the middle. Then you had to tie it so that it would make and oval. The next step was really hard and I didn't get it.

Next you had to add one yellow bead, then a white bead, and one blue or red or any other color. Same thing with the other side. Then you had to bring the left wire and put it through the color bead and the white bead. Same thing with the other side. Then you have to pull the wire together and keep pulling until it makes a tiny oval shape. You have to repeat it twelve times. After that you bring your ornament to the teacher so she can do something. 

After that you take the left wire and put it through the yellow beads. Same thing with the other side.

The most difficult thing about science last semester was learning the parts of the cell. At first when I saw it, it overwhelmed me. I thought I was going to fail the unit. What made it difficult was learning all the parts of the cell like cell membrane and mitochondria. There was just to much to learn. Then it started to get easier and I started to understand it more. I got some help from Mrs.Poole and it really helped me.

What I learned was the different parts of the cell. I have to say that this was the hardest thing to learn in science so far. I know it will get harder and I will struggle, but I will always ask for help so that I can do well. When the test came, I was a little bit overwhelmed. I tried my best and I ended up getting and A on it.
