Part 2:
What was the purpose of this video? How does the producer of the video use rhetoric to support their purpose? Give three pieces of evidence from the video to support your claim. (Example of evidence can be narrator’s tone, the information presented, information not presented, music played, and/or images shown.)
  • Sal uses an informational tone to convey ethos, that he continues this throughout the video. This calm almost monotone voice really speaks to how he is only going to be going over the scientific aspect of this problem.
  • Sal presents factual scientific information (like explanation of how the two versions are different) in order to give the audience information and information only. This allows him to appeal to a scientific and studious pathos  
  • Sal uses a formal logos that shows clear info and logic backed up by reasoning in order to remove most opinion from this video. For example he logically walks us through when each type should be used instead of just presenting facts he explains them in a logical way.


  1. What diseases do vaccines prevent?
    1. Protusus
    2. Polio
    3. Varicella
    4. Rotavirus
    5. Strep sepsis
    6. Meningitis


  1. What is herd immunity?
    1. According to vaccines.gov “When a critical portion of a community is immunized against a contagious disease, most members of the community are protected against that disease because there is little opportunity for an outbreak. Even those who are not eligible for certain vaccines—such as infants, pregnant women, or immunocompromised individuals—get some protection because the spread of contagious disease is contained.
    2. This is challenged when people get exemptions from vaccines
    3. This causes the herd immunity to become less strong
  2. What does it mean to be immunocompromised?
    1. A medical term that means that your immune system can not get rid of pathogens as effectively as a normal person could an example could be a chemo patient


  1. What kind of people would be considered immunocompromised?
    1. Chemo patients
    2. Old or young people
    3. People who are already infected to a different virus
  1. How does herd immunity help people who are immunocompromised?
    1. Helps them by making viruses that are vaccinated less common so it reduces the chance that an immunocompromised person would be exposed


  1. What does it mean to “exempt vaccines”?
    1. To get a legal allowance to not have a child be vaccinated by opting out


  1. What two ways can parents “exempt vaccines”?
    1. Personal or religious beliefs


Part 2:
What was the purpose of this video? How does the producer of the video use rhetoric to support their purpose? Give three pieces of evidence from the video to support your claim. (Example of evidence can be narrator’s tone, the information presented, information not presented, music played, and/or images shown.)


  • Purpose: bring sensational light to the
  • The producers of the video choose a narrator with a deep intelligent voice to exude an ethos of intelligence and authority on a controversial matter as to calm the human need for controversy.
  • The video presents both sides of the argument to show logos in comparing both sides of the discussion but gives much less time to one side. By giving some representation of the opposing side in the last video the producer tries to make you feel that the examination is logical and covers all bases.
  • The video is made appealing to a wide pathos by using sensational words like “war” on vaccines. This stirs up passion and emotion, which can distract a watcher from true introspective thought.


Video #3 (For today, just watch the first 16 minutes of this video to complete the activity)


Part 1:
  1. What is the theory behind vaccines?
    1. Prime immune system to defend against certain things and next time you are exposed have quicker response


  1. What is the stigma around a person who questions vaccines?
    1. That they are immediately against all vaccinate in any form or type
  2. What is “informed consent”?
    1. Whenever you do a medical procedure you have to inform about benefits, risks, and alternatives


  1. Do doctors give “informed consent” to patients on vaccines?
    1. To a legal extent yess but handing a piece of legal document to a family to save time should not be enough


  1. Who controls vaccine laws?
    1. The state government controls instead of federal


  1. What is California’s vaccine law? (Not mentioned in video, please Google it.)
    1. Only medical exemptions


  1. How much knowledge do doctors receive about vaccines in medical school?
    1. Very little about what is inside effects or choices just benefits and when you can give them


Part 2:
What was the purpose of this video? How does the producer of the video use rhetoric to support their purpose? Give three pieces of evidence from the video to support your claim. (Example of evidence can be narrator’s tone, the information presented, information not presented, music played, and/or images were shown.)


  • Purpose: bring light to problems in vaccine administration and education and opinions
  • The video is presented as "the truth" about vaccines as if to suggest someone is lying to the viewer, and the only way out is to trust them. This creates false authority by necessity.
  • The documentary immediately starts out with an explanation as to why questioning vaccines isn't the same as being completely anti-vaccine. The documentary does this early on as not to dissuade a pro-vaccine audience from watching.
  • Also the documentary use title blocks under speakers with their qualifications. They are kinda hard to read but just having them there is meant to affirm us that the information is coming from a qualified individual.
Summary Questions:
 
  1. What is the “vaccine war”?
  2. The vaccine war is a "conflict" of ideas that people have of vaccines. Some believe that vaccines are the only option and are to be administered always, and some question this. Over time this difference of ideas has become more and more aggressive. People who question vaccine usage are often labeled as anti-vaccine.


  1. How has media shaped the “vaccine war”?
  2. Media has caused ideas to spread faster and allowed for dramatization, not a discussion of topics. videos like the first and last, do not allow for discussion but simply a dramatized representation of a topic that does both sides a disservice.


  1. How has researching vaccine ingredients, learning about the immune system, and watching three videos with separate agendas helped you?
  2. I have not changed my position on whether kids should be administered. Doctors should be better introducing risks and be getting more education on the vaccines. But I believe that they are necessary to maintain herd immunity.

Blood Lab

Introduction: According to a study by Neil A Zakai published in the Journal of thrombosis and haemostasis, “Blood type AB is associated with an increased risk of stroke that is not attenuated by conventional stroke risk factors and factor VIII levels were associated with 60% of the association. While blood type AB is rare in the U.S. population, it is a significant stroke risk factor and may play an important role in stroke risk in these individuals” (Zakai). This study illustrates the importance of knowing your blood type and the risk factors that come with it. It is very simple to determine your blood type and much harder to understand what a blood type actually means in terms of antibodies, antigens, immune responses, and blood transfusions. In NEW school we had the opportunity to determine our ABO Rh blood type, and, of course, I took the chance.


Purpose Question: What is my ABO and Rh blood type?


Hypothesis: If my blood has antigen Rh and only antigen Rh  presenting on the surface of my red blood cells, then my blood will agglutinate when placed in anti-Rh antiserum, because the Rh antibodies in the serum clump around the Rh antigens that are presented on my red blood cells.


Typing Tray
Materials:


  1. 1 Lancet
  2. Blood typing tray
  3. 3 Plastic Toothpicks
  4. 1 Cotton ball
  5. 1 Bandage
  6. Bottle of rubbing alcohol.
  7. Tub full of Bleach-Water Solution
  8. Lancets and sharps box
    Infectious Sharps Bin
  9. (1 drop of each) Anti A, Anti B, and Anti Rh Antisera




Procedure:
  1. Add a drop of each antiserum to each corresponding basins in the tray
  2. Adding Antisera
  3. Clean your index finger with rubbing alcohol on cotton ball to sanitize the area
  4. Use lancet to prick finger and squeeze blood out of the hole
  5. Use plastic toothpicks to transfer blood to basins one at a time, while mixing them and using a new toothpick for every basin
  6. Look closely at each basin and observe whether the blood is agglutinating.
  7. If it is  agglutinating mark a yes in the column which  corresponds to the type of antiserum your blood agglutinated with.
  8. Sanitize materials in bleach bath and dispose of lancet in sharps box

Conclusion: Red blood cells are similar but differ in that they have either have or don't have several antigens (proteins), and are classified by the presence or lack of three different antigens. Antigens are proteins that can be found on the outside of cells, including your red blood cells. Your blood contains antibodies (more proteins) that peruse the cells in your blood. When the antibody "sees" a cell with antigens that don't match the antibody signals for a lot of other antibodies to be produced. These antibodies are slightly different: they swarm around the foreign antibodies that didn't match the original antibody. This signals for the white blood cells to attack the pathogen. This process is part of both the innate and acquired immune system.  So, if you get a blood transfusion with blood cells with antigens that aren't the same as the ones on your blood cells the process will be carried out on those blood cells. This causes many issues. But, there is hope: the blood transfusion does not have to be from a donor with a  perfect blood type match because as long as the blood does not have antigens that your blood does not have, your antibody won't recognize it as different and therefore won't attack the foreign blood.  My blood type is O+ because my blood agglutinated when exposed to to anti Rh antiserum. When my was blood introduced to to anti a, b, and Rh antisera, my blood only reacted with anti Rh antiserum. This means that the Rh antibodies in the Rh antiserum swarmed around my  red blood cells because there are Rh antigens presented on the outside of my blood cells.  And, since a similar reaction did not occur with the other two antisera, my blood does not have a or b antigens presented on my blood cells. Our results seemed completely conclusive and encountered no significant variables. Next time i would like to carry this lab out in a more sanitary environment and look at the results under a microscope to be absolutely sure of my blood type.

Immune System Q and A

The first line of Innate Immune defense

Neto Demoing the effect that mucous has on pathogen entry




After watching the Neto’s Demo on the immune system I now can answer the following questions.
  • What is the point of the immune system
    • keep out pathogens( virus, bacteria paricites fungi)
    • your defense system
  • What is the difference between the first line of defense
    • keep things out
      • skin mucus oil acidic environments like stomach 
  • What is non-specific immunity mean?
    • an immunity that responds to generally everything that seems bad
    • does dot know what it is dealing with just attacks
  • inflammatory reponse= bringing stuff to the fight
  • phagocytes: cells that can eat up pathogens  use sensors to detect and eliminate invadersby enveloping it becomes phagosome
  • major histocompatibility complex II (MHC II)? 
    • a protein that takes broken up peptide chains from the broken up pathogen in the phagosome that then takes it to the outside membrane  so it can help reconize
  • What is an antigen?
    • a protine/ pep chain that can be delt with in the specific imune system

Virus Notes

Today we watched this video to gain insight on viruses.

  • first discovered 1901
  • are everywhere
  • ingest millions every second
  • pretty much everything has a virus that targets it including viruses themselves
  • viruses are very tiny
  • contain rna or dna
  • needs host cell to replicate
  • turns cells into virus producer
  • needs to have matching memrane to virus receptor
  • why some viruses target specific types of cels
  • usees virus rna and enzymes to take over protien producton of cell
  • cell helps make new viruses
  • make many new viruses inside until they burst
  • posible that a virus was the first nucleus

Sci Assessment 7 Re Vamp

To reflect on my performance on Sci Assesment 7 I watched 2 videos in areas that I struggled.
I often Mix up independent and dependent variables while reading test questions. I created the following sketch notes to end my confusion. I came up with a compassion for IV-DV in a medical IV line. IV lines can have their contents changed to elicit a reaction from the patient or the DV.



My group also struggled round water. I did not know that we get water from melted snow. This is interesting because some years we get a lot of snow but others almost none, this must hurt the water supply.

gled with the identification of where drinking water comes from. This video explained that most drinking water comes from snowmelt and

Eco Demo




Ethanol would be the best fuel to burn because of its high energy density and its clean burn.
Ethanol burns blue and therefore clean. Also it has a high energy density which make it an efficient fuel. Over all the best part about this fuel is its low co2 emissions. It is very hard to create enough of this fuel on the other hand because it is hard to farm corn to the extent that is needed to produce enough ethanol to support our infrastructure without harming the environment.

Impacts with Audrey

Today Audrey taught us about the environmental impacts of fossil fuels



Vocab:

  1. air pollution: mixture if air particles  and gasses that contaminate the atmosphere
  2. Global Warming: used to described how greenhouse gasses are trapping heat waves   and raising earth's temperature
  3. Co2 emission: the production and discharge of co2 into the atmosphere
  • Coal releases methane 
  • lasts hundreds of years
  • air pollution
  • acid rain
  • mercury lead and arsenic
  • Oil emits co2 global warming
  • sulfur dioxide   acid rain
  • nitrogen oxide    respiratory
  • can also cause oil spills
  • kills of marine life and creates a marine life food web domino effect
  • gas
  • methane 
  • ethane 
  • propane
  • causes natural resources to diminish
  • can not be replaced quickly

Fossil fuels With Kelly


Today, Kelly taught us  about
fossil fuels and their alternatives
  • formed when  organic matter decomposes when heat and pressure are applied over long periods of time, needs special conditions
  • internal pressure high heat and time are the conditions
  • renewable resource: a substance that can be replenished as fast as they are being drawn out
  • fossil fuels are not renewable bc they can not replenish fast
  • energy efficiency: the corresponding amount of energy produced by a given amount of fuel
  • 11 tons of oil used per year
  • 2088 there will be no more fossil fuels
  • clean energy source: an energy that does not pollute the atmosphere when used
  • think solar geothermal and wind
  • energy yield is much lower than fossil fuels
