Cells
We started class by Mr.Finley telling us that he fixed the study guides. Then we watched a video and answered these questions...explain what you see. Is this living, nonliving, dormant, or dead? What is the evidence? The last question was what type of cells are these if alive? What is your evidence? (Animal, plant, or bacteria. Eukaryotic or prokaryotic). My answers to these questions were, I think I saw an oval like thing that had hairy things around it and I thought it was single-celled organism eating or attacking something. It is a living thing. My proof is it is moving and seems to have DNA scattered through it. My last answer was it is a bacteria cell because it is moving and seems to have DNA and all the parts that bacteria has which makes it a prokaryotic cell. We all saw different things which we never decided on what was what. Then as a class we decided that it was an animal cell because it jiggles, doesn't have a cell wall, and it a cillia. Bacteria and plant cells do have cell walls. We also decided that it had to be living because it seemed like a cell. Then we looked at two pictures of bacteria under an electron microscope. They had capsules and cell walls so you coudn't see through them but the animal cell in the video was see through. After this we watched another video with paramecium eating yeast that was dyed red.

Science Class
After that, we were told to write three paragraphs in our notebooks each answering a question that was on the board.
- The first question was: "What are the similarities and differences between bacteria, animal, and plant cells?"
- The second question was: "If I say I am looking at a prokaryotic cell, what does that mean?"
- The third question was: "What came first, prokaryotic cells, or eukaryotic cells?"
For the first question, we said that the plant and bacteria cells had cell walls and the animal cells didn't. We explained that bacteria cells can survive on its own. We also said that animal and plant cells have organelles and bacteria cells doesn't (like...nucleus', endoplasmic reticulums, mitochondrias, golgi apparatus', etc.). In addition, bacteria cells have hair and most animal and plant cells don't (multicellular). The reading told us that these classifications would be that plant and animal cells are eukaryotic cells and bacteria cells are prokaryotic cells.
For the second we said that it means to look at a cell with no membrane-bound organelles. Such as bacteria cells.
Lastly, for the third question we said that prokaryotic cells came first because it was the first basic cell. It later evolved into eukaryotic cells. Like bacteria cells came way before humans and plants.
After we finished writing the three paragraphs, we discussed it by looking at a picture of bacteria, animal, and plant cells. That was the science class in Mr. Finley's 7th period class.
- Prokaryotic Cell: A cell that doesn't have any membrane-bound organelles within it (like mitochodria).
- Eukaryotic Cell: A cell that does have organelles within it.

microscpoe lab
Methylene blue is necessary because... we think that that the cells are clear, so the methylene blue will make it blue. It made the cells visible and the air bubbles are completly white.
The dye can get inside of the cell because... it's like a sifter, the mythylene blue is small enough to get inside the cell.
Yes we do think the cell is made up of parts, because it had small lines, and a decent size circle.
Next we went over the anwers. Mr. Finely took another sample of his cheek cells and put it under the microscope that is atached to the smart bored. He put no methylene blue in the sample and all we could see were air bubbles. Next he put the methylene blue in as it was still under the microscope. The cells started to show up as the methylene blue went through the sample avouding the air bubbles and the cells showing up as it went.
Now Mr. Finely is sending people out to get 2 samples of grass. Next he made everybody that wasn't getting grass samples get microscopes and set it up. Then he said to break the grass in two so both groups could have one. we put one drop of water on the slide and then we put the grass on the slide. Next we put the cover slip on and put it under the microscope. We observed that it had little craks on it . We will comtinue tomorrow.

Cell Lab
Today we started class by hearing a bad report from the sub. We were very bad and Mr. Finley told us he was very embarresed because she is a friend of his. He then told us to take out a peice of paper and write a letter apologizing to him. He also told us we will not be doing the lab we were supposed to do. After he collected the letters he told us about the biology test we will have to take to pass 9th grade biology. He told us we had 7th and half of 9th grade to learn everything we need to know. He then read something from an older sample test. He then told us we had to watch the lab be done on video and our expert microscope group did not have a great presentation yesterday. He showed us notes/tips 4th period wrote about microscopes, using them, adjusting things, and slide plates and coverslips. Nect we talked about the lab. We were supposed to do it using our own cells but we had to use Mr. Finley's cells. The best cells to look at are cheek cells. These are the best to use because they are big and they constantly come off. To get the cells we gently rub the flat tip of a toothpick inside our cheeks and gently rub it on a slide. We were also supposed to use methylene blue. This is used for many things. We would use it to dye the cells to see them easier. We also learned that using it would make the slide a wet mount slide. If you happen to use a little too much methylene blue you can put a tissue on it but don't rub, gently place it on top to absorb some. This is the process of making a wet mount slide. We then learned about filters and what they are used for; seperating bigger and smaller things. Then Mr. Finley showed us the slide of dyed cells on the computer. They look like little small flower petals from far away but as they get closer they look more like petals from flowers. To finish up we sketched the cells and answered question.

New Unit Introduction
We thought back to the beggining of the video when it said that everyone lives in house in a block in a town or a villiage. Which makes a city in a state that creates a country that lies on a continet and the continent lies on a planet like earth With this we found the main idea which is that everything is made up of something smaller. Examples were that galaxies are made of star systems that are made of planets that are made of continents, etc. With this we found out that humans are made of organs which are made of tissues which are made up of cells etc. This then led us to a discussion to figure out if organs are made up of tissue of muscels. We agreed that if the organ has muscels it has to have tissue as well because muscels are made up of tissues. In addition, we found labeled some of the systems of the human body which are- circulatory, nervous, immune, digestive, respiratory, circulatory, skelatory, muscleatory etc. After that we said that the systems are made up of organs like the heart, liver, kidney, stomach etc. Then we said that organs are made up of tissues which are groups of cells working together. Lastly, we said that tissue is made up of cells. And Mr. Finley told us that in this unit we will learn about what cells are made up of.

Starting bacteria
Finishing amount of bacteria
After watching the video, we shared and discussed the observations that we made from the video. Also, that's when we talked about binary fision and why the bacteria doubled themselves hundreds of times.

October 22nd P7 -JP
First, we were talking about our lab reports which should have a hypothesis, conclusion, data, and your procedure. "For your procedure you must number your steps in order," mr. finley had stated. Just important reminders for your lab report. Second, Mr. finley talked about the observatioonal experimant that led to your hypothesis. You should probably include your observational experiment in your backround section. Your backround should be the first part of lab report. It sets up or makes a backround for your experiment. More specifically it is everything that leads to your experiment.(Important statements Mr. Finley made). Next we learned about our graghs. Basically Mr.Finley made sure we knew how to make a gragh.
Things to make a line gragh
1-Equal spaces between each axis lable.
2-Independent variable should be on the x axis.
3-Equal intervals between each axis lable.
4-Do not have to start at zero.
5-Scale should be an easy number to work with.
6-Lable each axis.
-Lable x axis with your independent variable.
-Lable your y axis gragh with your dependent variable.
7-Lables have to include units of measure.
8-Need a title
9-And ofcoarse put your data on your gragh.
10-Connect the points and/or draw the trend line.
11-Then try to find patterns or relationships between your independent variable and your dependent variable. This part is very important for understanding your gragh.
12-Your trend line does not have to be straight. Your trend line should touch some points and not touch others. A trend line is basically a genral line of the data on your gragh.
Next we worked on our graghs for our bacteria. If you missed class I can only say that everybody's bacteria grew. We did our usuall everyday basis of taking measurements, and adding to our graghs and coming up with more patterns.

cholera is a darrheal disaease caused by the bacterium Vibrio cholerae. it is active in nearly 70,000 villages and covers about 110 milion people.
hiv stands for human immuno defficiency virus. causes aids and there is no vaccine available. in 1980s, the first case of aids began. hiv is caused by infected blood cells. 1985 there was the first lisenced aids blood test was conducted. 1/2 million people die a year from aids a year in the u.s.

Period 7 Concept map/consensus
This class was not filled with confusion and it was pretty smooth. In class I was confused but this class helped me understand what the vocab we have been using in class more. Also this class helped me learn how to make a new graph of organization called a concept map. Finally I learned what concensus means. It means that a group of peopple agree on one idea out of all of theirs. I think that some other students were confused as well but i think at the end of class we all understood the concept.

Period 7 - Epidemic
Above is the website we used today.
We are trying to figure out if there is an epidemic at a town. We viewed the absences and found out that there were days where everyone was at band and other days where one third of the students were absent. We found out that most of the students where out on 5/20 in all schools. We also found out that a lot of the restaurants were doing unhealthy things. In some of the schools the ceiling tiles where missing and wires where exposed. There might have been the West Nile Virus. Classes with more people had more people absent. The students where back at school very quickly so the students might have gotten better quickly.
Today we looked at the band schedule for Jackson Middle School and Truman Middle School. The Jackson Middle School and Truman Middle School seemed to do a lot of activities together. We also looked at the reasons the students were absent and the symptoms they had. Most of the symptoms where the same in both schools so the might have the same disease. When we looked at what the parents said about the students being absent, they said it might be food poisoning or the flu. They all came back to school very quickly. There might be a epidemic at the schools.

Period 7 - Patient Zero Experiment
To start off the experiment, we tested out who Vinny traded his fluid with. And he traded with LB, JM, JS. So Stephen believed that it was Jake that is patient zero. At first we agreed, but when we continued the tree diagram, it showed that Jake is not patient zero. After that we tested who Jonathan traded with, he traded with JP, NM, and SD. We found out that he might have been patient zero. To check our hypothesis, we saw who Jordan traded with. He traded with SF,SB, and CT. After, that we tested who Jimmy traded with. He traded with JP and SD, and they turned out to be sick after they traded with Jimmy. But when Sophie traded with NM, she also got sick after trading with Sophie. We know that Jimmy and Sophie are definitely patient zero. This is because everyone they traded with, got sick.
