Friday Blog post
Next we started 2 labs. One on page 13 and the other on page 16. We received 2 petri dishes. For the first lab we took the one with the cross shaped divider and labeled the sections on the back 1-4. Then we took samples of 3 different places around the school and put them in sections 1-3. #4 is the control group. Then they were put in an incubator.
For the second lab we took a petri dish that was not divided but on the back we still labled 4 sections. then we took 3 different kinds of antibiotics and one little piece of paper and put them in each section. One antibiotic in each section but 4, which had the paper in it. We put this in the incubator too.

Cholera and John Snow
Since I am such a John Snow fan...i found these videos that i thought you might exjoy. Watch them and email me the answers to the following 2 questions..
1. Who was often spared from cholera outbreaks and WHY?
2. What was the name of the other 'protagonist' in Stephen Johnson's book Ghost Map?
Sadly It's Not Friday.....
After Homework we did the disease of the day (pretty depressing name)!!! Today's disease was Cholera (Mrs. Stein's favorite disease!)!! Cholera is a bacteria that causes diariah and can kill if proper attention not given.
Then we took a good amount of notes on bacteria. We talked about Binary Fission (how the cell reproduces), shapes of bacteria (rods, spheres, and corkscrews), and stuff like that.
Afterward we watched a movie on bacteria and antibiotics. The movie explained how antibiotics are just a tiny bit of the bacteria (or a simmaler bacteria) that get your body used to it so your immune system knows ho to get rid of it without totally infecting you with it.
HOMEWORK.....
UP 2 due: 11/1
THE NEXT SCRIBE IS........

When we walked into class, we turned in our cancer papers. then we talke about the small pox video we saw yesterday (see Mrs. Steins blog post).
Then we took notes on viruses...
Notes:
"What is a virus?"
*Non-living-
- require a host to reproduce-"parasites"
- don't use energy
- NOT CELLS!
- don't respond to stimuli
*Particle made of protein, nucleic acid
- protein-capsid
- nucleic acid- DNA or genetic material
*Invade cells, hijack cells
- attach to cells and trick membrane for entrance
------------------------------------------------------
LAB
After the notes, we did a lab on UP pages 6-9. The lab was called, "Who Infected Who?". We had to get into our lab groups and try to figure out who were the carriers of a disease. We got some information of people from a school and had to make a wed of disease transmission. then we got samples of "saliva" from the people that we picked to test for the disease and dropped some disease indicator solution in it. if it turned pink, tha means that they are a carrier of the disease.
Homework
- Finish UP pages 6-9 -due tomorrow
- Read in text book 20.2 with "In picture and in words" -due wednesday
- QUIZ THURSDAY!!!!
- post card -due 11/8 (we got paper for the post card today in class)

ALMOST FRIDAY
We have begun class by receiving a new Unit Packet, a new class Syllabus,a diagram for our notes, and a Student Summary Detail Report. There was also a group of papers that have yet not been picked up from yesterday.
If you had any questions regarding about your Cell Test or anything else with your Detail Report, you should talk with Mrs. Stein after class.
Notes:
We have been given notes from slides about our new unit DISEASE AND IMMUNITY! :D yay :
1) Infectious Disease:
- Disease - Any change that disrupts the body's functions
- Pathogens - Agents which cause infectious disease
- Germ Theory of Disease
- Infectious disease are caused by microorganisms.
- Bacteria
- Viruses
- Protists
- Worms
- Fungi
3) Spread of Disease
- Physical contact - direct and indirect
- Sexual Contact and airborne
- Contaminated water or food
- Poor sanitation, raw meat
- Animals like insects & rats which carry disease are vectors
- Rabies, West Nile, Malaria
- Robert Koch - German Scientist (Late 1800s)
Game:
After we took these notes we played a game called Zapper. Everyone stands in a circle and everyone received a card with either Zapper (1) and a player (everyone else) for the first game. The zapper (disease) will wink (attack) a player (other cell) and the player will sit down (die). In the second game a vaccination card was thrown in the cards and if the zapper will look at the vaccinated player (vaccinated cell) the cell will not die because they already know how to handle with this disease therefore they live.
Homework:
- Do pages 4 and 5 in the Unit Packet but cross off the first four empty boxes under What That Game Element Represents on Page 4. And cross off number 3 on page 5.
- Remember to do your cancer paper that is due this Monday, October 25. It has to be turned www.turnitin.com and in a hard copy by that day.
- Remember to do extra credit! The next upcoming date will be this Saturday from 9 to 12 at the Glen.
THE NEXT SCRIBE WILL BE: Taylor

Highlights of Friday
Prophase is the first phase of mitosis. During this phase genetic material inside the nucleus condenses and the chromosomes become visible, and outside the nucleus a spindle starts to form. The nucleolus disappears,and the nuclear membrane starts to disappear.
Metaphase is the second phase of mitosis. The nuclear membrane completely disappears and the chromosomes line up in the middle of the cell.
Anaphase is the third phase of mitosis. The chromosomes seperate and move along the spindle fibers to the opposite ends of the cell.
Telophase is the final phase of mitosis. The nuclear membrane and the nucleus reform during this stage. Cytokinesis is almost done and the chromosomes uncoil to chromatin.
Thursday, October 14, 2010
It's Thursday????
So today in class we talked a little more about mitosis and we learned this cool way of remembering all the phases ask about it in class if you missed it
Then we took a couple of notes on Prophase,Metaphase, Telophase and Anaphase
since I can't find them on moodle I'm putting the video that Mrs.S showed us:
http://http://highered.mcgraw-hill.com/sites/0072495855/student_view0/chapter2/animation__mitosis_and_cytokinesis.html
a couple questions that came up in class were:
Q:Are the proteing used in cells the same type of protiens that we eat?
A: Yes and No. The proteins we eat get broken down and are then used by the cells. Think of them as legos. You have a cool lego piece and the little blocks are the protiens used by cells
Q: Telophase in Animal cells vs. Plant cells (not really a question but you catch my drift)
A: In Animal cells they pinch apart and with Plant cells they form a Cell plate in between the two cells, it's baiscially an add-on to the cell wall.
In class we also did a Mitosis lab it started on page 44 in the unit packet and this first lab was baisically understanding mitosis. You can do this at home easily. This first lab was mainly to get us ready for the second one we will be doing tomorrow. It has to do with identifying the stages in Mitosis. The second lab we will be doing in class it starts on page 48 in the unit packet and goes to page 51.
Also, don't forget about your Cancer research paper! don't procrastinate about this! The 25th is a lot sooner than you think! Today we talked about citations within text and that is for example:
tra la la la la (someone's last name and a page number if it's a primary source).
the period always goes after the parentheses and other things that could go in the parentheses if the author is missing:
-A company say you got it from the American Cancer Society
-an abreiviated version of the title
Homework:
1. UP pages 44-51 due at the end of class tomorrow
2. Cancer paper due 10/25/10
in other news: Max turns 4 months today! woooohooo!! <3
and the scribe is.....Angela!!!!
Mitosis is fun

(: Happy Monday :)
Today, bio passed by very quickly! When you came into the classroom, we picked up some papers that Mrs. Stein graded for us. We went over everything that we received back:
-The Normal and Plasmolyzed Cells Lab
-Animal and Plant Cell coloring Assignment
-the Cell Structure and Function lab
-the cell quiz that we took on Thursday
Mrs. Stein also went over one of our homework assignments: we must complete a survey about our risks of cancer. The link to the survey is on Moodle. The survey is about how mush we are at risk from different types of cancer, but don't do all of the tests (check which ones girls have and which ones boys have). In total, all of the surveys should take 40-45 minutes, so each survey should take 3-5 minutes to complete.
After we finished going everything over, we quickly added to our notes:
Catalyst
-a substance that speeds up a chem. reaction
-decreases that amount of energy needed to start the chem. reaction
-doesn't get used during the reaction
Enzymes
-proteins that act as biological catalysts
-enzymes are very specific
-subtrates fit like a "lock and key"
-affected by chanes in pH, temperature, subtrate concentration
Then, we took the class's data from the enzyme lab we worked on last week.
group 1: 0.5 C 70 mm
group 2: 18 C 105 mm
group 3: 22 C 10 mm
group 4: 37 C 103.333 mm
group 5: 53 C 102.5 mm
group 6: 98.3 C 7 mm
(Mrs. Stein said that some groups probably made human errors, because the numbers didn't exactly turn out the way they were supposed to. The height of bubbles should be highest at 37 degrees, because that is the temp. that we are mostly at within our bodies (98.6F), and the bubble height should have been shortest at the lowest temp.)
After we collected all of our data, we went over how to make the graphs. The first graph should be the graph of your own group's data. This should be a bar graph.
The second graph should be of the classes data. This is going to be a line graph. Make sure that you write your number correctly on the graph; they must have order, they can't just be written in random places.
At the very end of class (the last five minutes), we got a chance to get started on our homework!
The homework for tonight is:
-Finish the enzyme lab (graphs and analysis questions)
-Begin Cancer Survey (Complete Graph on pg. 55 in unit packet by Wednesday)
- Ch. 10.1 and 10.2 flow map "cell cycle" - g1 to cytokinesis
P.S. The next blogger is...

ENZYME LAB!!!
In class- In class on October 8th we did the enzyme lab! First off enzymes are proteins that speed up chemical reactions in cells. The enzyme we used in this lab was catalase, which is found in blood cells and also some other cells. Catalase speeds up the break down of hydrogen peroxide into water and oxygen.
Enzyme Lab! (pages 24-32 in UP)- In this lab we tested the amount of enzyme activity in different temperatures. You measure the amount of enzyme activity by how high the bubble column is in the test tube. For part A we had to test how the catalase works. You had to set up 3 test tubes with two marks on them. One mark 1 cm from the bottom of the test tube, and one mark 5 cm from the bottom of the test tube. In test tube #1 we put catalase in up to the first mark and hydrogen peroxide up to the second mark. Then you had to measure how high the bubbles rose from the second mark in millimeters. Then we did the same thing with test tubes 2 and 3 but with different contents. Test tube 2 had water to the first mark and hydrogen peroxide to the second, and test tube 3 had catalase to the first mark and sucrose solution to the second, and recorded the height of the bubbles for all of them. Once we knew how the catalase worked we went on to part B. In part B we tested how the catalase worked in different temperatures. Each group was assigned a different temperature and you had to get your water bath to the correct temperature. If you had a hot temperature you heated it up, and if you had a cold temperature you had to put ice cubes in it to cool it down. Then you had to fill the test tube to the first line with catalase and set it in your water bath so the catalase got to the correct temperature. We had to monitor the temperature of the catalase with a thermometer until it was at the given temperature. When it was at the right temperature we put hydrogen peroxide in the test tube up to the second mark and measured how high the bubbles rose. If you had enough time you were supposed to do another trial for more accurate data. Here are some pictures from our lab:
Catalase reaction to hydrogen peroxide...
Cooling down our catalase to 15 degrees Celsius...
Our catalase reaction at 15 degrees Celsius...
Fun Sunday Adventure!
Yellow Indian Grass
October 9th Restoration Day at the Grove: I found out that in order to cut down buckthorn it had to have rained the prior day. Since today was such a beautiful day, the Grove had a day for people to help out in other ways. Today I went and helped pick seeds at the Grove to help restore their prairies and grasslands. We picked the seeds from each of the plants and put them in brown paper bags. Above i attached pictures of two different plants that we picked to get seeds from, which were the Yellow Indian Grass and the Turkey's Feet. These two plants are native plants to the Grove and many of the invasive species are taking over their land. These plants will die before the winter and then the Grove will replant the seeds and the snow will push them down into the soil. While picking the seeds, the leader told us a lot about the Grove's land and how much they appreciate our hard work.
In 1836, the Kennicotts came to the land and Mr.Kennicott was the first doctor and mail man in the area. He became a famous scientist and that's why they ended up keeping the land and naming it the Grove. Mr.Kennicott started the seed business and started planting all different plants to sell throughout the area. When they got to the area known as the Grove now, they had 800 ares but they now only have 123 ares. This is because we have built buildings, roads, houses, banks, and much more on the land that once belonged to them. The leader told me that not only are the invasive species taking over the land of these plants but so are we. Helping them by picking the seeds is a great way to keep these plants in the Grove. I learned today that a pound of the Yellow Indian Grass could be sold for about $100! Wow that's a lot!
I had a ton of fun helping out at the Grove and they want me to tell u guys that they need more helpers!!!
