It's Almost Friday!!!!

Above are some pictures of what we talked about in class and what we veiwed in our lab.

IN CLASS:

*First, we showed Mrs. Stein our homework from last night. Which was a pre-lab on page 8 of our packets, and our bubble maps for chapter 7.1 in our text books. Mrs. Stein also stamped our stamp sheets.

*Next, we looked over Michelles's blog from yesterday and did stars and wishes

*Then, we took notes on our new unit that we started yesterday: Types of cells

*Some people took a microscope test to see if they could get a slide in focus within one minute (not many people did well :P)

*Lastly, we began our lab- UP 9-14

NOTES:

Major Cellular Regions:

*Plamsa Membrane - outer boundary of a cell

*"Nucleus" - contains DNA

*Cytoplasm - gel-like substance between the cell membrane and nucleus

*Cyto- Cell

*Plasm- Liquid

HOMEWORK:

*Read 7.2 with organelle chart- due on Monday

*UP 9-14- due Monday

*Extra Credit

ABOUT THE LAB:

For the lab, we got into our groups from before during the Rip-o-meter lab. Then, we took a slide, the first one was of an Eloda Leaf, and then put it under the microscope and looked at it under high power. After that, we recorded a picture of what we saw and gave the picture a title and wrote down the magnification that we veiwed it under. Next, we answered some questions about what we saw. For the slide after that we did the exact same thing except we put a drop of iodine on the Eloda Leaf. The slide we were to observe after that, was of a human cheek cell. However, most of us (including my group) did not get a chance to complete the whole lab.

HAPPY ALMOST WEEKEND AND HOMECOMING!!!! :)

Our next scribe is Jose!!!

Wednesday, September 29

Beginning of Class:

• Once we have settled down, everyone has gotten a Student Summary Detail Report (basically, your grade report). If you had any questions about this, you should have a talk with Ms. Stein in private.
• After that we have talked about the cluster map here on the blog and that someone in the middle of the US has checked it out .. creepy.. To make it even weirder Mr. Sheller comes in the room with one eyebrow cocked and looks over us and then leaves.

• After all this commotion we have all picked up our new Unit 3 Packet and the blue assignment sheet if you didn't get one earlier.

The New Unit!!

• The new unit is about cells. And the theme is cancer. What is cancer? Cancer are mutated cells that can divide/multiply out of control. This process is commonly known as mitosis.

• The class has brainstormed for a minute of what we knew about cells. After that we shared our thoughts with the class.
• After we got the general idea, we went over a couple power point slides Mrs. Stein has put up on the smart board. It mainly discussed the levels of organization, the cell theory, and cell specialization. It was basically a review but you should get the notes from a friend just in case.

Microscopes

• Do you remember we had to rate ourselves on our test on Tuesday of how we can perform with a microscope without looking over the guidelines in our packet? Well, after we took our notes we were put into assigned groups (so there is one person who knows extremely well how to handle a microscope and one person who can use some more help) and practice how to use the microscope.

Homework and Upcoming Quizzes:

1. WE HAVE A QUIZ TOMORROW OF HOW TO HANDLE A MICROSCOPE WITH A SLIDE!
2. We have to read 7.1 and take double bubble notes. You were to compare Eukaryotes Vs. Prokaryotes.
3. Moodle was down yesterday so you still have today to finish any discussion questions that you haven't done so already.
4. Rememeber to do extra credit! Only one visit counts for points but volunteering more for fun won't hurt!

The next scribe is Ariana

REVIEW DAY!!!

IN CLASS: Today in class before we really even started we picked up our graded Lab 58, the worksheet we did while watching "Planet Earth," our rip-o-meter lab write up, the comparison chart we made for section 6.4, and our stamp sheet. Then we talked for a little bit about Yvette's post. After we went over what the homework for tonight is she answered any questions we had about the concepts on our unit packet(pages 1 and 2) or about the test in general. Then, we played a review game of jeopardy covering all of the topics we talked about in our ecology unit. We played girls versus boys and....the girls won!! Yeah girls!!

What should you do for studying..?

-Review objectives from UP pages 1&2

-Review notes

-Review what we read from the textbook

-Go to review sessions in room 374(day before test 3:00pm, day of test 7:00am)

-Go to http://gbhsweb.glenbrook225.org/gbs/science/stsbio/revsheet.htm and play the review games but..WARNING--some of the things on the review are not current so make sure this isn't the only way you study!!

-Practice questions

-Old quizzes

-Labs, reading strategies, worksheets..

-REVIEW AND UNDERSTAND DIAGRAMS!!!!

Homework:

1) Video comments and moodle forum-you are supposed to post a detailed comment at least for of our classmates videos and respond to the questions Mrs. Stein posted on moodle. You should read the comments before yours so you can respond to the question and also other peoples posts. This is all due Wednesday.

2) ECOLOGY TEST TOMORROW!!!!!!!! Make sure you study for the test using the tips above.^^ There will also be a review session before school tomorrow in room 374 at 7:00 am if you missed the one after school. If you can't get there at 7:00 it's okay you can still pop in if you have a quick question or want to review for a little bit.

3) Extra Credit! There are various dates to earn extra credit at many places. Mrs. Stein thinks the most fun one is at the Grove(: See the "Extra Credit" post for all of the dates/times/info.

Today was mostly a review day but a fun one also. Good luck on the test tomorrow!!!:)

The next scribe will be Michelle.

oil spill video!!!

7th Period Class; Ecology. 9/24

In Class:
The day started off normally. We first read the blog from last night and did the "star/wish". After that, we quickly went straight to finishing up our notes on global warming and the ozone layers, which were to be finished up on Thursday, but we got off topic. (: In other words, we are a lot more behind than Mrs. Stein's other STS Bio classes. 20 minutes before the class was over, Mrs. Stein took us to the math computer lab to: help out people who were having trouble uploading their oil spill video onto the blog, and also allowed us to start our homework. (scroll down to see a better description of what the homework was)


Notes: In class, we finished up our Ecology notes that were about Global Warming and Ozone Layers.
These are the rest of the notes of what we took in class on Thursday!

Greenhouse effect: natural situation where heat is trapped by CO2 methane and other gasses.

EXAMPLE : http://www.environmentalsociety.ca
Mrs. Stein thinks of a Greenhouse effect as like a " blanket wrapped around the earth to keep it warm."

Effects of global warming:

• Rising of sea level
• Loss of biodiversity
• Natural disasters

Ozone Depletion: A layer of O3 gas in the atmosphere.
^ filters harmful UV rays (sunscreen for the earth)^ 1970's scientists found that CFC (chloral floral carbon) caused a hole to form in the ozone layer.^ CFC's were used in aerosol cans and were banned in 1987^ Ozone holes are shrinking


HOMEWORK:
* Alien Poster: is to be printed and handed in on MONDAY in class. (print in color. make it neat, creative, and colorful)

* Blog comments: This was the homework that we were given time to work on in the computer lab. This assignment involves going onto the blog, looking at four or five classmates oil spill videos, and write good, age appropriate comments about them. ( in other words do not just write, "cool video. loved the music". Mrs. Stein wants the comments to include facts about the video. She wants you to prove to her that you've watched the video carefully and paid close attention to what your classmates had to say about their point of view on the oil spill.)

* Moodle forum: Log on to moodle. Scroll down on moodle to Unit 2- Ecology. Click on 7th period - Video Response. Answer the two discussion questions asked by Mrs. Stein about global warming. If you do not have enough information about global warming, watch the two videos that go along with this assignment. They are only a couple minutes long.

* Extra Credit: Extra Credit information about The Grove is up on the blog. Check the times and dates in order to go and help out!
last thing.....
STUDY FOR THE ECOLOGY TEST ON TUESDAY 9/28
Review and extra help is available MONDAY MORNING or MONDAY AFTER SCHOOL. Ask Mrs. Stein about more information. That's about it. oh and p.s. we didn't get off topic on friday, meaning we are not behind anymore! (:

the next scribe is Madison.
