Cuttin some Buckthorn


In this Picture I'm cutting down the invasive Buckthorn bush. For the past 2 years I have been participating in workdays by the Chicago river to try to eliminate Buckthorn. On this day we cut down other plants as well but our main focus was Buckthorn. It was explained to us by the project leader that Buckthorn poisons the ground not allowing other plants to grow. Then it will spread its seeds and take over the area. By cutting them down and dabbing herbicide on the top of the stump this can kill the bush and alows new life to sprout.

Fridays Class

Fridays class had a sub. In the beginning of class we got our home work checked in for a stamp (UP- 12). After we got our homework checked in we went over it. We specifically discussed problems 8 and 9 because some people had difficulty answering those problems. After we talked about homework we talked about Influenza.

Influenza
  • Virus
  • endemic/respiratory infection transmitted by casual contact
  • treatment for symptoms only
  • prevented by vaccines and sanitation
  • 40,000 in u.s year
  • one million world wide

A video about Influenza ---> http://www.youtube.com/watch?v=FvEOjwUOzJc


After discussing Influenza we went over the lab (UP 13-18 ).

Lab: How common are bacteria and how quickly do they reproduce?

The purpose of this lab was to learn about sterile techniques, expose nutrient agar to 3 objects to determine if bacteria are present on the objects, observe bacterial colonies on your agar plate, evaluate your sterile techniques and determine places where bacteria are likely to be found.
The four objects/surfaces my group tested were, 1- Locker, 2- water fountain, 3- top of a hand sanitizer bottle and 4- was unexposed.




The picture above is an example of what the trays looked like only our trays were cut in fourths.


Homework

UP 13-18
Post card 11/8
READ 20.3 w/ double bubble map "Bacterial vs. Viral Disease" - Monday

CLEVER TITLE FOR MY POST

When I first walked into class today I was all psyched for the test! Then we proceeded to take the test. After the test Mrs. Stein assigned the days homework which was...

Homework:
1)UP 12-due tomorrow
2)read 20.3-double bubble map "viral disease v.s. bacterial disease" -due monday
3)post card-11/8

After the homework was assigned we watched an interesting video on Malaria. In the video we learned many intriguing things.
*Over one million die of malaria a year
*Malaria is caused by a parasite that invades red blood cells
*Malaria enters the body through mosquito bites
*MANY african children are suffering
*Many Places all over the world used to have malaria until DDT was used to kill mosquitos that spread the disease, it killed much more than just the mosquitos and was banned-Africa was never reached with the chemical so malaria still remains in Africa

It was crazy to think about America at one point suffering from malaria. The video brought up some very interesting factoids about malaria. When the video finished so did class.

Super Awesome Post

Hey everyone sorry for not posting yesterday but this one is going to be an amazing post that is going to make up for it. So this first section is going to be all about yesterday or 10/26. So our Agenda was as following

-Take out UP 6-9 w/ stamp sheet
-Star and Wish
-Go over lab
-notes on viruses
-video on viruses
Homework
-20.2 "Picture and words"
-Quiz Thursday so study
-post card 11/8

The Lab that we went over was the who infected who lab. In the lab hopefully everyone found out that ed was the carrier (a carrier is someones who has the infection but shows no symptoms(just in case you forgot)). Also Marriam and Tran tested negative for having the disease. Your final web or chain of infection should have been, Mr.Paek gave it to Heather, Heather gave it to ed (the carrier), and then ed gave it to Mrs. Dillion, Laura, and Mr. Wegley. Note that Mr. Wegley could have given the disease to Laura. Following our discus ion on the Lab we started the notes on viruses.

The first slide showed us the Viruses come in variety of shapes.




these are the different cells that were shown in the diagrams we were shown

our next slide was about the lysogenic cycle



Viral Disease

- How Do viruses cause disease?



  • Attacks and destroys cells
  • Disrupts homeostasis

- Common viral diseases:

  • West Niles, HIV, Chickenpox, Flu, Warts

-vaccines may prevent disease

-Antibiotic DO NOT work against viruses


This was the last of the notes for Tuesday.

After the notes we watch a video for a little bit on diseases and cholera and other topics under viruses.



Today...yay!!!


Today we turned in our 20.2 notes or kept them and got them stamped so we could study them. During this time I was reminded that I forgot to Scribe. Then i was informed that i had to make this post super awesome (which it totally is). After that little discussion we talked about the disease of the day which is cholera. After that we started our noted on Bacteria and everything about it......well....not everything cause that's a lot of info, we would have to be genius. Anyways after the notes which ill share with you in a bit we watch a movie about a lethal bacteria that can help cure hyper muscles. In the movie they were talking about how the bacteria is the most lethal bacteria in the entire world. but at a thousandth of the lethal doce it can be used to relax muscle. This bacteria is now also used in Botox.


The notes:

Bacteria
-Unicellular
-prokaryotic- no nuclear membrane; one chromosome found in cytoplasm
- ribosomes

metabolic Diversity


Energy Source

-heterothophs get their energy from other organisms

-autptrophs make their own food

  • Photosynthetic
  • chemosynthetic

Respiration

-obligate aerobes requires O2

-obligate anaerobes w/o O2

-Facultative anearobes w/o or w/ O2

Binary Fission

-DNA replicates,and the cell divides in half

conjugation

-exchange genetic material across a hollow bridge (pili)

Spore Formation

-ENDOSPORE may form under harsh conditions

-Spores stay dormant until conditions are favorable

-Protects DNA


These were all the notes that we did, study these and good luck on the quiz.

Today we also did a disease of the day. To day it was cholera, the notes are as follows.

Cholera

-Bacteria

-Diarrhea

-Transmitted through contaminated food and water

-Treated by antibiotic

-Prevented by purifying water, sewage treatment, and proper cooking.

-1000,000-2000,000 deaths a year worldwide

Thank you for listening and reading my amazing awesome post have fun reading all of this during class and don't forget to check out the videos and pictures that I'm going to post:D

John Snow and Cholera







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?

About The Day: 10/25/10


This morning we started the class off by turning in our cancer papers in the red bin. Then we discussed our thoughts on the Small Pox film from last week. We will be watching more videos from this series later on in the year. We answered questions and wrote them down from our homework. Mrs. Stein brought up the epidemic in Haiti and how it relates to today's lab (Who Infected Whom? UP 6-9). The point of todays lab was that there was a virus being spread in GBS. Many people were coming down with this illness. Out of all the people that got the illness, one person was carrying the illness in their body but they had no symptoms. This person is called a carrier. In our lab Ed was the carrier. We did this lab until the bell rang. If you need help with the Picture+ Words here is the general format.

Homework for 10/25/10:
-Finish UP 6-9: due tomorrow
-Read 20.2 w/ "In Picture + Words": due Wednesday
-Postcard: due 11/8/10
-Quiz Thursday

The next scribe is Alex
