Period 7 Blog

Today in class we did, we signed into the website. Also we are covering over what we did yesterday. If you were out yesterday then go to yesterdays blog. Basically to sum it up yesterdays dusscion we were talking about how the child (male) goes through puberty and then they develope sperm cells in meiosis. Now today we are talking about what happens to a girl, today, and how it is different from a male. Now on the website we went to Genetics and clicked on Pea Soup! Then dont even read that thing that pops up. Just there is a button that says Click for the experiment. OR something like that. CLick on that, and just write down that is on the screen. Copie that down without doing the actual simulation. Youjust write what you see. Here is what my group saw. We saw two parent cells ans 4 daughter cells. The colors of it could be green or yellow. There is upper case letters and Y's and R's. Same textures as the parents. Half of the kids look like one parent and the other looks like the other parent. There are little circles all by the children. Those are called radio buttons and you can click them. You chose two peas and breed them together. Then they become the parents and then they have 4 children. So now we are playing this game. So the point is to breed the children correctly 5 times in a row. On the same website. Loriks group prediction is that 1/2 is going to look like one of the parents and the other 1/2 will look like the other parent. Here is what we will have to do. -hypothesis -prediction -test -check outcome matches -then revise hypothesis. -then try to figure out what the letters mean If your peas look the same no matter what x out and start again Thats what we did in class today! ALSO WE HAVE A TEST A WEEK FROM TODAY ON MEIOSIS KK

First we came into class. Then we review the rules of the activity that we started yesterday. The objective of the game is to get the one group to say the message in English, but they can not talk. In the beginning the group that couldn't talk sent a message to us asking what we did. We told them that we can decoded things. Then the group that couldn't talk sent us the message. We decoded the message and sent it to the group that needed to read it out loud. They didn't now what to read it at first. We sent them a message saying to read it out loud. We had won the game. Then we answered some questions on the whiteboard. What part of the cell was table A? The answer is they was a nucleus because they started with the original message and had to transfer it and copy it. Also it sends signals to the organelles, like they did in the game. And the nucleus copies DNA just like they had to copy the message. Second question was what did the message represent? It represented DNA. The nucleus stores DNA like blueprints. The last question was what were the purpose of the rules? The answer is so it was like a real cell. The nucleus can't move just like group A. The kids sitting in a circle was the membrane of the nucleus. Only a copy of DNA can move like the copy of a message. They couldn't talk because the membrane can't communicate. Next we started to take notes. The nucleic membrane has little pores in it for transportation. DNA can come in different forms. There is Chornatin which is like twirled spaghetti. There is Chromosomes which is like two rubber bands rolled up. Lastly there is a Double Helix, which is like a twisted ladder. A section of each Chromosome is called a gene, which has traits. DNA stands for deoy ribo-nucleic acid. It is basically two sugar strings twisted. It was a good day. We took some fast notes, but got to finish our game which was fun.

Today Mr.Finley said that if you blogged during the presentation last month and you didn't like your blog you can redo it at the end of the month after the blogging cycle is over. We made a web that started out with Dead then we defined it as was once living and had all the characteristics of life. Living is that it has the characteristics of life now. Then nonliving never had any of the charateristics of life. Dormant is Lima Beans, Acorns, and Yeast, these things could become living if you add something to it , like water.Dead and dormant can be to diferent things or they come under living or nonliving. Mr.Finley said there is no wrong answer.After that we discussed the homework from Thursday. first, we discussed wether or not a plant cell is an organism. Then, Mr.Finley asked us what a cell was which is the smallest living thing in life.

Then, Mr.Finley said that cells can be organisms, but they don't have to be. That was what we did today.
