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

Video Thoughts?

Did anyone have any thoughts about Friday's film? I have seen that film many times now, and everytime I watch it I always really admire those 'disease warriors' who worked so tirelessly to bring vaccines to remote parts of the world. I feel that so many people are only concerned with themselves... to travel to places like India and Africa to try and rid the world of such horrible diseases really says something about those volunteers.. They really made a difference in the world... not everyone can say they have done so. How amazing would it be to be able to rid the world of HIV like they did with smallpox? What were your thoughts? Reply to my post with a comment as to what your thoughts or reflections were on the movie.

Re-seeding at the Interpretive Center

This saturday I went to the Interpretive Center at the Air Station Prairie.

For the time I was there, we gathered the seeds of a plant that were going to spread when the wind came, unbalancing the ways of the prairie.

By the end of the morning we had gathered many bags that looked like this.These seeds are to be taken to other locations where invasive species, such as buckthorn, has been cutdown and the land is in need of another plant.

In front of the prairie was a building that ran on the solar panels on the roof and a wind mill in front. Also the tables and all materials used were made out of different recycled woods that could been removed without having the tree die. They also had countertops that were made out of sun flower seeds.

Not only did the solar panels and wind mill provide electricity, it also heated the building and the water.

Overall, I learned a lot about the air station and the prairie, a part of my town that I never really knew about.

Cancer Paper

what should the font size be for the cancer paper????? and if there is no article and you get your info from, for example WebMD, do we just put that in the citation??? also are you just not able to use 'you' in the opening and conclusion, or the entire paper????

"Teach Me How to Bucky?" Scribe- October 21, 2010

Hey Class!

On October 21, we started off class by listening to Mrs. Steins new favorite song, "Teach Me How to Bucky", while writing down the homework for the weekend. Next, Mrs. Stein had us go up and get our homework checked in (which was pages 4 and 5 from the Unit Packet) and she also gave us a NEW homework stamp sheet. Then, we discussed our homework and the zapper game from last class. We went over how the Zapper game and viruses are similar. We discussed how computer viruses and disease-causing viruses are alike, as well. Since someone was absent the day we played the Zapper game, we begged Mrs. Stein to play it again. So the entire class played two more games of Zap! After that, Mrs. Stein pulled up the slide show and we took notes on "Spread of Diseases". We learned that diseases are spread by physical contact, contaminated food or water and vectors which are animals that carry diseases. Lastly, we watched a video about "Disease Warriors. This video was interesting because it showed us how viruses could be spread, wether it was from another person, or by animals. It also showed how some vaccines were created. Earlier in class we were assigned homework for the weekend. The homework is the following:

~Read section 20.1 with 6 questions AND answers

~Watch out, Grandma! Disease postcard project ( Due November 8th)

~Remember to finish the Cancer Paper (Due Monday)

If you need any rubrics or the format for 6 types of Q's and A's, then look on Mrs. Steins homepage!

The next Scribe is....... Adrian!

"Does everyone know how to wink?"

Hello! So In todays class, we did many things. We started off with everyone recieving a grade report, then you collected your papers off the lab benches if you did them. Although Mrs. Stein didn't hand back our tests, the grades are on the grade reports. If you have any special questions or if you want to go over your test, please go to the TLC or ask her for special questions. Also, by now you should have your turnitin.com account completely set up. If not, ask Mrs. Stein for help. Or you can look on moodle. While discussing the cancer paper assignment, which is due monday, we talked about plagerism and how to site your quotes and information. Dont cheat! Also, Mrs. Stein said that she will be posting a link on moodle to show you how to correctly site your information.
Next, We started our new unit on infectious diseases. Heres a little bit of the notes that we took:
Disease: Any change that disprupts the bodys functions.
Pathogens: Agents which cause infectious disease.
We didnt take many notes today, because we spiced it up and played a game! ZAP! In this game, you tried to avoid getting "zapped" by the person who was infected by the disease in which our case was Swine flu. In the second round, a little more than half the class was vaccinated and there was still one zapper. I think that a lot of people in the class really enjoyed this game!
Hw for tonight: - UP 4-5
- Finish your cancer paper!!! Due Monday. ( If you need a copy of the rubric, look on moodle!)
Thats all! The next scribe is... Caroline! ^.^

October 18, 2010

Hey guys, sorry for the late post...anyways, here's what we did in class yesterday (as today was a BIO DAY!!! I mean c'mon how interesting was that? "I had a little birdy, his name was Enza, I opened up the door and influenza"...haha so weird!!!!))
First we started off by turning in our multi-flow map and since Mrs. Stein's computer was down, we skipped the star&wish for Michael B's blog. Make sure to check out his blog and to comment on it.

Then when began to take notes in class, and I titled mine "Cancer Notes"
Here's how they looked:
Plant cells:
-Cell plate forms between cells.
-No centrioles.
-Spindle fibers
-Stages of Mitosis (PMAT)*
Animal cells:
-Centrioles
-Cell pinches at cleavage furrow.
(SAME AS PLANT CELLS):
-Spindle fibers
-Stages of Mitosis (PMAT)*
*Note: PMAT stands for the four stages of Mitosis; prophase, metaphase, anaphase, and telophase.

Then we went on to try to understand PH, which can be found in your text book on page 43-44.
Notes involving PH:
Acid is at a PH level at 14, a neutral is at a PH level 7, and a base is at a PH level of 14.
Examples: acid: stomach acid, soda; neutral: pure water; base: soap.
-If more positive charges than negatives, then it's classified as an acid.
-If it has more negative charges, then it's classified as a base.

We moved onto another section of notes: regulating the cell cycle, which is what our previous HW assignment was on; here are some notes:
-Cyclins are proteins that regulate the cell cycle.
-Spindle formation is during Interphase.
Ask yourself this question: What does DNA control?
And answer with this (one): DNA contains the instructions for making important proteins.
Note: If this goes wrong or bad, then the cell can either: 1) divide out of control or 2) not divide at all.
-The cell has internal regulators that check and make sure the cell is ready to go through Mitosis. (Spindle fibers, replicated DNA, etc.)
-External regulators, on the other hand, are out signals meant to help speed up OR slow down cell divison. P53 is an external regulator.
(Note: such as wound healing or contact inhibition.)
-Caginogens are things that cause cancer, such as the follow:
~tobacco
~UV rays

That was all for the notes we jotted down in class on Monday, here's the homework:
-SIGN UP by TODAY for TurnItIn.Com
(Steps: 1. Click "NEW USERS CLICK HERE"
2. Click "New Students start here"
3. Click on Create a User Profile
4. Choose student in the next window avalible.
5. The class ID is 3574346, and the password is our teacher's last name, no caps.
6. Enter your information that it is asking for.
7. Create a password that is 6-12 characters (LETTERS & NUMBERS) long
8. Choose your helpful question.
8. Click I AGREE
9. Log in!)
-Cancer Paper: 10/25...must be on TurnItIn.Com AND have a paper copy, as well.
-Cell quiz/test on Wednesday

That's all! The next scribe is Jordan.

Good luck studying, everyone!

..?

so uhm where on moodle do you find the id's for turnitin.com???

TURNITIN.COM??????????????????????????????

I was able to creat an account on Turnitin.com, but the website denied my Class ID and the Enrollment Password when i tried to enroll in this class!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?!?

period 2 sts biology

Today in biology we started out class by discussing and taking notes on why cells reproduce. I learned that cells reproduce for three main reasons. 1. To replace dead cells in case of an accident like a cut or wound. 2. To keep a cell from growing to large, it needs to follow the cell cycle and split every now and then. 3. To let the body grow and develop through childhood. If cells would not reproduce then we would not be able to live, grow, and exist.

After discussing we were given time to finish up the lab from the day before. we quickly set out our microscopes and started filling in our lab in our lab packets. If you did not finish the lab it is not to be completed for homework. Mrs. Stein is giving us an opportunity to come in before school Monday morning to finish it!

The homework for Monday is:

read pages 43,44 in text book skip buffers.

read section 10.3 in text book up to 52b-52d and create a flow map

Cancer paper is due on 10/25

Create citation account by tuesday

Sorry, forgot to post the homework.
up 44-51
cancer paper 10/25

Mitosis

Biology was very interesting today, as always. Mrs. Stein started off the class going over web recources we can use for our cancer research paper. We can either go to science resources or the libguides. Next she went over how to cite our bibliography and what to do after a sentence that you took from a resource. You have to use the MLA guidlines. Next we went over the guidlines for the paper. The format can be what ever you feel like is proper. the rubric consists of:

• Cover page 1 pt
• Grammar, Spelling, Format 2 pts
• Analysis of Cancer Risk Graph (in your intro) - Estimation of Cancer Risk (UP 55) 2pts
• Research on One Type of Cancer 7p ts
• Prevention 2 pts
• Conclusion 2 pts
• Visuals 2 pts
• Bibliography 2pts
• Citations and Appropriate use of resources
• Inclusion of "Estimation of Risk Graph" (UP 55) - colored appropriately
• http://www.turnitin.com/ - submission on time (you must still hand in a hard copy)
• Total pts: 25

Next, we watched the mitosis video that Mrs. Stein showed us. It showed all the stages of mitosis. Then, we took notes on Mrs. Stein's mitosis lecture. The notes:

1. Prophase

• 
  
  chromosomes condense
• 
  
  nuclear membrane dissapears
• 
  
  spindle fibers form as centrioles move toward poles

2. Metaphase

• 
  
  chromosomes line up along center
• 
  
  chromosomes attach to spindle fibers at centromeres

3. Anaphase

• 
  
  sister chromatids seperate and move toward poles

4. Telophase

individual chromosomes gather at poles

nuclear membrane reforms

5. cytokenisis

• 
  
  cell pinches in half
• 
  
  two cells form
• 
  
  animal cells - cleavage furrow
• 
  
  plant cells - cell plate

Finally, we did the lab, where we observed and labeled onion root tip mitosis.

*The Cell Cycle*

We always learn something new in Mrs. Stein's classroom every day.

Since today was late arrival with thirty-five minute classes, the class began by walking in, picking up a sheet and a picture, and sitting down. The sheet was our homework, and the picture was to tape into our notes. After organizing ourselves, Mrs. Stein asked for everybody to have their stamp sheet and their Estimation of Cancer Risk Graph located in the UP packet (55). Continuing the morning, Mrs. Stein had notes on the Smart Board for everybody to copy down - there is a picture of them on the left of this scribe. The notes were on the Cell Cycle and basics about it. The cycle has four stages, in which chromosomes take place. The cycle consists of: Interphase (G1), S Phase, G2, and the M Phase. Cells undergo these stages in order to grow, replicate, prepare for mitosis, and finally, divide. Chromosomes are in the cell, and they are the ones that do the jobs. After taking notes for about twenty minutes, we were allowed to work on our Mitosis (65) Worksheet. We had to annotate, and on the back, color the appropriate structures the appropriate color. Since that was fifteen minutes, the bell rang and class
was over. We walked out with our heads filled with science and looking for tomorrow.

HOMEWORK:
1) Annotate the Mitosis worksheet (with notes in the margins!), and color code the back.
2) Start Cancer research.
3) Cancer essay due 10/25.



















The Homework. ^ ...... >

Extra Credit!!! Shhhh!!!! It's a secret!

Click on this picture and play the Cell Cycle game!  Who is the "supervisor" in the game?  Email me the answer!  Extra credit will be awarded to the first 5 people from each section who email me the correct answer PRIOR to the start of class.  Don't tell anyone. Shhhhh!

Hey everybody!

Monday's class was pretty busy. We started off the day by recieving back privious work.We were handed back our cell structure and function lab, oil spill video rubric, cell quiz, cell color code, and grade reports. Mrs.stein went over the answers on the cell quiz (if you want to go over your quiz you can go to the TLC and get some help). Then we talked about the homework, which is- The enzyme lab (lab on up 24-30) and to read 10.1 and 10.2 with flow map and title it "cell cycle"-go to moodle or see your blue packet for help and examples. Next we were told to report to the math lab on tuesday to begin our cancer risk survey and if we had time left over to begin research on our cancer paper. Later we took a few quick notes, which should have been review about the lab. The notes were...

Catalyst

• A substance that sppeds up a chemical reaction
• Catalysts decrease the amount of energy needed to start the chemical reaction
• DOES NOT get used during the reaction

Enzymes

• Proteins that act as biological catalysts
• Enzymes are very specific
• substrates fit like "lock and key"
• Affected by changes in PH, temperature, substrate concentration

Lastly each group gave data about their enzyme lab. The data we gave was the temperature that our individual group was given and the average height of the bubble. The whole class copied down the data and discussed why the data was the way it was. Our data should have shown that there was the highest bubble at 37 degrees celsius because that is our body temperature, so enzymes are working the most at that temperature. Our class data was kind of different and Mrs. Stein said that we probably did some lab errors, but its fine. When we were done collecting data we worked on our enzyme lab questions for the last few minutes left of class. 


The next scribe is Izabella!

Enzymes

Here is the picture I showed you in class. It does a nice job illustrating how an enzyme works.

Enzyme Lab

{Sorry this post was kind of late guys...but my computer was having trouble connecting to Moodle}

Agenda:
Enzyme Lab
UP pg. 24-32
turned in UP pages 36 & 37
got a stamp for Enzyme Pre-Lab wrksht

Homework:
Enzyme Lab due Tuesday
Read 10.2 & 10.3 by Tuesday
(do a Flow Map titled "Cell Cycle" on 10.2)
[Flow map available on Moodle]


In class on Friday we talked about the Enzyme Lab that we were going to begin that day. We discussed that the beaker of water that served as the "water bath" had to stay at the temperature you were given and it was supose to be like a practice test just to observe what happens. Afterwards we did the trial with the assigned temperature we were given which was either 0, 15, 22, 37, 55, 0r 100 degrees Celsius. My group was assigned 15 degrees Celsius, and we were also suppose to do the trial a multiple number of times and then record our data.

Also in class Ms. Stein showed us an example of the lab we did. She poured hydrogen peroxide in a graduated cylinder and then added potassium iodine to cause close to the same reaction as our lab. It was really cool to see because the hydrogen reacted so furiously to the potassium that it overflowed an extreme amount into the plastic bin it was in.

Te next scribe is Mirella

Plasmolyzed Cell Lab!

Agenda:

1. QUIZ!

2. Bring up 34-35 with stamp sheet

3. Discuss diffusion lab and osmosis in cells

4. Discuss pH enzymes and tomarows lab

5. Plasmolyzed lab (UP 36-37)

Homework:

1. Finish Plasmolysis lab (UP 36-37)

2. Prelab for enzyme lab:

a. Use section 2.4 in textbook for extra help

b. Lab on UP 24-30

When we first got to class we took the quiz. After that we got our stamp for the diffusion lab. Next, as a class we discussed the diffusion lab and answered any questions we had. Mrs. Stein then explained how osmosis in cells works. She explained that a cell might have 99% water and 1% salt in it, while its in a puddle of 6% salt and 94% water. If this happened then the cell would get rid of all the water in it because it moves from high concentration to lower concentration. When this happens, the cell membrane gets smaller and squeezes all the chloroplast into the middle of the cell. Then we witnessed this for ourselves by doing the Normal and Plasmolyzed Cell lab. We ended the class by working on the Analysis questions. If you dont understand this read page 211 in the textbook.

Plasmolyzed Elodea Plant Cell (in salt water):

Elodea Cell (in tap water):

The next scribe will be: Gabby

The Sausage in the Cup

Today we did a lab which was an example of diffusion. diffusion is when one object passes through a cell or a cell membrane into a less densly populated area. The lab that we did involved a plastic tube about 7 inches long, 200ml beaker, glucose solution, an iodine solution, and a soluble starch solution. First we got the plastic tube and tied a string tightly to the bottom of it, then we filled it with the starch solution. After the tube was filled, we added 20 drops of glucose into the starch. Meanwhile the others in the group filled a beaker with water and added a good squirt of iodine into the beaker.

Then we put the plastic tube into the beaker and waited. while we waited we reviewed some of the organells that we have a test on for tomarrow.

When we came back the glucose and the starch had a purpleist tint to it. We later learned that the iodine from the beaked had diffused into the plastic bag. it did this because there was a large population of iodine in the beaker and some of it wanted to get into a less populated area.
That is how the lab went so we cleaned up and and started on answering the questions in the unit packet.
Homework :
-Finish diffusion lab, Pgs.33-35
-STUDY FOR ORGANELL QUIZ!





















The next scribe is Natatlie

Lab Questions

Ok. I'm very confused, one of the questions says the starch didn't diffuse and i thought it did. So did it or didn't it???? Help me please!

Cells 10/5/10 Scribe Post

Hello everyone!

We started off class today by turning in our "Check My Understanding" sheet (pages 226-228 + 250-251) which was due today. While we were turning the homework in, we collected two papers from the counter. The large green paper that we got was the "Prelab for Diffusion Lab" and the other small paper was a diagram of cellular respiration. Next, Mrs. Stein showed us the rest of the slide show which gave us information about the mitochondria(converts chemical energy), biochemical energy(cells store and release energy using ATP), cellular respiration(energy fomr glucose is released), lysosomes(breaks materials down into small molecules to be reused), vacuole(stores materials), cytoskeleton(provides support/shape and is involved in movement) and cell walls(provides protection and support). Mrs. Stein said that if you could not finish all the notes, then she would have the slide show posted on the blog. After watching the slide show, Mrs. stein explained the homework to us. Also, Mrs. Stein announced to us that the Cell Quiz will be on THURSDAY instead of Wednesday.

The homework is as follows:

-Read diffusion prelab on pages 33-34 in your Unit Packet.

-Finish color code and annotations

-Read all of 7.3..... If you were in my row, Mirella's row, Dana's row or Amandas row, you were assigned to do ENDOCYTOSIS and FACILITATED DIFFUSION and the rest of the class was assigned to do MOLECULAR TRANSPORT and MITOSIS. (ex. http://gbs-moodle.glenbrook225.org/moodle/file.php/1521/Reading_Strategies/Definition_Mapping.pdf)

-Reminder: there is still time to do the extra credit!

For the remainder of class, we worked on our homework!

Sorry... I wanted to upload pictures but it wouldn't let me :(

The next scribe is Joel

Cells

Hello everyone! Today was pretty much a normal day in Bio...

We started off by turning in and/or getting a stamp the homework from yesterday:

1.) UP pgs. 9-14
2.) The organelle chart (stamp)

Next thing we did was we went over the organelle chart. To make things more clear on the different functions of all the structures in a cell Mrs. Stein showed us a slide show. In the slide show she showed us information about the nucleus, ribosomes, ER, golgi bodies, and chloroplasts. If you missed the slide show or missed something you can find the slide show at the bottom.


For the rest of class we worked on homework or did the microscope test (if it wasn't done already).

The homework is the following:

1.) Finish colorcodes w/ Annotations of readings
2.) Read pgs. 226-228 and 250+251 w/"Check My Understanding"
3.) Quiz Wednesday!

Cells ppt (ch 7)

N/A

Hello.
This is Sam.

This Friday we finished up the lab for the majority of the period. Your groups are the same people that you worked with on the rip-o-meter lab. During the lab Mrs. Stein took students and tested them on how well they did when working with a microscope. Once the period is over we cleaned up after ourselves and left.
For if you didn't finish observations or was absent, here are the things we looked at:
Frog blood
Cheek Cells

Homework:

• Read 7.2 and Complete the Organelle Chart (Chart available on moodle)

The next scribe is Captain Chloe.
