We got a lot done last Thursday.
We decided what we going to do.
Below is the address of the video we watched during our meeting on Thursday.

Service learning last Thursday
During our meeting last Thursday, we discussed about what we want to do. Some people want to do C.H.O.P( Children's hospital of Philadelphia) and other people want to do the homeless shelter. We decided to breaking down into two groups. We was thinking about maybe break-off into two groups or do the C.H.O.P first and then we do the homeless shelter. Mrs. Madhi received a letter from C.H.O.P., and we watched a video clip from C.H.O.P. website that has information about C.H.O.P.

Gene Mutation- Bio
A gene is essentially a sentence made up of the bases A, T, G, and C that describes how to make a protein. Any changes to those instructions can alter the gene's meaning and change the protein that is made, or how or when a cell makes that protein. There are many different ways to alter a gene, just as there are many different ways to introduce typos into a sentence. In the following examples of some types of mutations, we use the sentence "The fat cat ate the wee rat" as a sample gene:
Point Mutation
A point mutation is a simple change in one base of the gene sequence. This is equivalent to changing one letter in a sentence, such as this example, where we change the 'c' in cat to an 'h':
Original
The fat cat ate the wee rat.
Point Mutation The fat hat ate the wee rat.
Frame-shift mutation
Frame-shift mutations. In a frame shift mutation, one or more bases are inserted or deleted, the equivalent of adding or removing letters in a sentence. But because our cells read DNA in three letter "words", adding or removing one letter changes each subsequent word. This type of mutation can make the DNA meaningless and often results in a shortened protein. An example of a frame-shift mutation using our sample sentence is when the 't' from cat is removed, but we keep the original letter spacing:
Original
The fat cat ate the wee rat.
Frame Shift The fat caa tet hew eer at.
Deletion
Mutations that result in missing DNA are called deletions. These can be small, such as the removal of just one "word," or longer deletions that affect a large number of genes on the chromosome. Deletions can also cause frameshift mutations. In this example, the deletion eliminated the word cat.
Original
The fat cat ate the wee rat.
Deletion The fat ate the wee rat.
Insertion
Mutations that result in the addition of extra DNA are called insertions. Insertions can also cause frameshift mutations, and general result in a nonfunctional protein.
Original
The fat cat ate the wee rat.
Insertion The fat cat xlw ate the wee rat.
Inversion
In an inversion mutation, an entire section of DNA is reversed. A small inversion may involve only a few bases within a gene, while longer inversions involve large regions of a chromosome containing several genes.
Original
The fat cat ate the wee rat.
Insertion The fat tar eew eht eta tac.
DNA expression mutation
There are many types of mutations that change not the protein itself but where and how much of a protein is made. These types of changes in DNA can result in proteins being made at the wrong time or in the wrong cell type. Changes can also occur that result in too much or too little of the protein being made

NHD Reflection
Vietnam War
Documentary
Amie S., Chengxian Z.
My topic was about Vietnam War. I learned a lot while doing this such as how the war started, conflict and compromise, and why the United States got involved. Why the United States got involved was basically what we focus on. Some people think that it was wrong that the United States sent troops to support the Vietnam because it caused more people and the soldiers doesn't know what they fought for. After finished this project, I have more knowledge about the Vietnam War.
Working with partners was all fine, but I was mad because 2 of my partners doesn’t do nothing. I was mad at that time but now its over and we done with this project. I gave up in the last minute, I thought my documentary was a mess and I didn’t want to work on it anymore, but Amie still working on it and I think the documentary was better that before.
Some challenges like the interview. The interview was pretty good, but the problem was that the sound was not clear. And the guy that we interview talked too much and it doesn’t fit into our questions. We were sad about it. Another problem was that doing a documentary and have to stay after school. Last time I stayed after school until almost 7:00PM, and I was worried about that my parents would call my grandma. So I called my parents to China.
I think I will do a paper next year, because I can’t work with a partner who don’t do nothing, I’m tired of doing things in the last minute. Doing a documentary has to stay in the school and do it. Its more easier than documentary.

chapter summary
-Chapter one starts on page 3 to page 12
(Summary)
In this Chapter it talks about how the Thomas family live, four people to a one bedroom apartment. How they are poor, how rats be coming out and Bigger kills it, and starts to play in his sisters face with the dead rat and scares her. Bigger mother stays on him about getting a job to help out with the family.
During this Chapter it basically talks about Bigger and his family how they are like dirt poor and they live in an one bedroom apartment, they have rats, yes rats not mice. That’s how bad they got it. Bigger kills the rat and acts like a big kid playing with the dead rat in front of his sisters face it basically killed her half to death. He’s lazy don’t want to get a job to help out his family. So Mrs. Thomas(Bigger’s) mother basically tell him to get a job all the time to help out with the family but he still doesn’t listen

Bloom's taxonomy
Bloom’s taxonomy
1. What happen after Bigger killed Mary?
Bigger place her body into a furnace. Ad he cut her head off because the body cannot fit into the furnace
2. What do you think would happen next after Bigger place Mary’s body into the furnace?
He burned her body, and he pretended like nothing happen. People will find out who killed Mary and what happen.
3. What questions would you ask Bigger Thomas if you meet him one day?
First I will ask him about his family, what kind of situation they lived.
And then I will ask him the reason why he killed Mary.
4. How was this book similar to ‘The wire’?
They both talk about murder and drug.
5. What would happen if Mary didn’t get drunk?
How many ways can you describe Bigger?
Mary wouldn’t got rape and kill by Bigger.
Bigger Thomas was a poor, twenty years old man who lives in Chicago. Anger, fear, and frustration.
6. What do you think about Bigger killed Mary?
I think Bigger has no reason to killed a white girl who got drunken.
