Test Today!!!

Today we took the Unit 4 Test on Diseases and Viruses. The test lasted the whole class period, so we didn't have time to do anything else. At the end, Mrs. Stein passed back a lab we had done.

Homework:
Read 12.2 with a reading strategy of your choice!
(Skim the chapter and think about which strategy would be BEST)
---Make sure that on the top of your sheet, you write why you chose this strategy (This should be only one to two sentences).

I will probably be the scribe for tomorrow too because we did not do much today!

STUDY STUDY STUDY!!

Today we started class by turning in our homework, which was the postcard to Grandma Gertrude and UP 32 and UP 37-42, and to read 35.4 by tomorrow. After we finished the tree map on the Immune System, the acquired immunity branch.

In acquired imunity, you should know that it can either be active or passive. Active immunity means that the body makes the antibodies. An example of active immunity is vaccines or exposure to the disease, and active immunity lasts for a long time. Passive immunity means that the antibodies are obtained passively. An example would be breast milk or injections of antibodies. This is more temporary than active immunity.

After, we got the chance to ask Mrs. Stein questions because, we have a test tomorrow!! STUDY HARD EVERYONE!! It's going to be difficult considering there's a lot of difficult material covered in the test. Remember to go over the objectives page in the first page of your yellow UP packet.

The test covers pretty much all of chapter 35 and chapter 20.

Remember to review...

VIRUSES
-capsid, bacteriophage, prophage, retrovirus
BACTERIA
-prokaryote, bacillus, coccus, spirillum, binary fission, endospore, conjugation, and nitrogen fixation.

GERM THEORY, KOCH'S POSTULATES, VECTORS

IMMUNE SYSTEM
-non specific defenses
*first line defense: skin, tears, mucus, saliva, cilia
*second line defenses: inflammation, fever, histamine signals, and increase in blood flow and fluids

-specific defenses:
Humoral immunity: B CELLS (antibodies)
Cell Mediated Immunity: T Cells (attacks your body cells)

REVIEW ALL LABS

LOOK AT DIAGRAMS AND PICTURES MRS. STEIN GAVE US

Please, please, please make sure you understand the objectives page, if not, go to the review session tomorrow morning!! GOOD LUCK TO EVERYONE!!! :)

The next scribe is...Anastasia :)

Reminder: Save Your Daylight

This Friday we started off by stamping UP 28-31. Then did the disease of the day, Lyme disease. Lyme Disease is caused by a bacteria transmitted through a vector, the tick, causing a bulls-eye mark.

Afterward, we went over UP 22-25. Then we took notes on "Specific Immunity". Next, we looked over 28-31 and answered a few questions on it as well. finally we finished watching the mythbusters experiment.


HOMEWORK
  • Postcard-11/8
  • UP 32
  • UP 37-42
  • Read 35.4-Tuesday

A Good Example of a TreeMap

This treemap was a challenging task!  Below is a sample from one of your classmates... notice the structure, how the categories are divided... this map came pretty close to "nailing" it!

The Spread of Germs

Today in class we first checked in the homework, looked over the scribe for the day, went over some of the tree map that was the night before homework, and finally watched the first five minutes of a Mythbusters clip about the spread of germs.

We also made another contribution to the Disease of the Day chart that we have been working on for the past week. Today's disease was Pneumonia which comes in the form of a virus, bacteria, of a fungi which are called pathogens. Pneumonia is transmitted by casual contact such as saliva or mucus. The disease caused an inflammation of the lungs and can be treated with antibiotics.

in the first half of the Mythbusters video, we watched Adam spread the liquid from the rig attached to the edge of his nose one drip at a time. after the first experiment was finished they turned off all of the lights and put all of the items covered by the liquid under the black light. it was surprising to see how far the mucus from one person's nose can spread to places not even thought possible is such a short period of time. The next experiment consisted of a party where Adam was hooked up to the same rig camouflaged so it looked like a irritated patch of skin. there were three people who knew about the liquid drippings and were supposed to avoid it as much as possible. There were also three other people who didn't know about the liquid drippings and were just invited to the party. Adam's party ended at the same time class ended so we have yet to see the ending.

HOMEWORK

-UP pgs.28-31 (use your book)
-Bio Day Tomorrow
-Postcard due 11/8/10
-Test on 11/9/10


THE NEXT SCRIBE WILL BE............................

Intertesting Tuesday*

In the beginning of class, Mrs. Stein went over the agenda, which included the homework pass. Mrs. Stein described how important homework passes are and when we can get them. The deadline is next Wednesday, November 10, 2010. They are really reliable to stay away from a zero on your grade print-out. Nevertheless, next we went over Dana's scribe from the previous day about the lab we did. We then transferred to another topic on how the results were surprising. Some had swapped dirty objects and some other objects that were not as quite obvious to have many bacteria.

The Disease of the Day is: #6 Tuberculosis. (In our 'Current Infectious Diseases' chart).
- agent of disease: bacteria
- endemic
-spread through air (airborne)
-infects lungs, brain, kidney, and spine
-treated with antibiotics

In class we took notes on Antibiotic Resistance.
This just basically included:
-natural selection
-mutation~spontaneous
-conjugation
-problem in hospitals

In relation to the D.O.D., Mrs. Stein asked the class who was born in a different country. Nobody raised there hands . . . except me. I was born in Poland, and therefore, I have the vaccine mark on the my left shoulder ( a little lower). Mrs. Stein also said that I am immune to Tuberculosis, but if they tested me here in the United States, I would come out positive. Also, Mrs. Stein added that this doesn't mean that I have it, it just means that the vaccine/antibiotic is resistant/not resistant towards the disease. (I didn't really know how to explain this very well...)

For the rest of the class, we got to work on UP 22-25 (packet). We could, with a partner or individually. It was based on Eva's story on when she fell from her bike. If we didn't finish, unfortunately, it became homework.

Today, was full of information.


The Homework:

-UP 22-25 - tomorrow
-"Immune System" Tree Map
  • read 35.2 / 1st page of 35.3-Postcard 11/8
-Postcard 11/8
-Test 11/9
  • HW Pass by next Wednesday!

P.S. If you have trouble with the tree map, here is the link to the format on Moodle:

Immunity Monday






Hey everyone sorry for posting way to late, but here is your recap of our Monday class.

We finished our two labs about bacteria that we had started on Friday with Mr. Peck. For the first lab we had swabbed different areas around the class room and some groups even went around the school. Each group swabbed an area and tested for bacteria by putting three different area swabs in a petrie dish and leaving on section blank as a control, but we had to wait over the weekend to find out the results.
For my group, we tested the floor of the classroom, the top of teh germ-x container, and a sink handle. WE found there to be the most bacteria on the sink handle which is quite surprising because the floor is very dirt and was our hypothesis for having the most bacteria.

The other lab we finished on Monday was about antibiotics. We put peppercorn broth on a petrie dish and put on that same petrie dish three different antibiotic discs and then another blank disc as a control. After waiting we got to see the results today.
For my group, we found the neomycin was strongest against the bacteria, having a bigger diameter of non-bacteria around it then the other antibiotics.
Today we also had our Disease of the day.

Today our disease of the day was Malaria.

Malaria
-The agent of disease is protist
-transmitted by mosquito bites
-attacks the human liver
-prevented by bug repellents and reduction of standing water

Homework...
- finish UP 13-18
-read section 35.2 and 1st page of 35.3 about immune systems and use the note taking skill tree maps
-- Due Wednesday
