Evolution!

Welcome Back!!!

After getting new seats, we started our new unit on Evolution! Everyone was REALLY excited! We started off by playing a game of written 'telephone' to illustrate how things can change over time.  In the process, we learned that we aren't the best artists! We then brainstormed a little bit about what we already knew about evolution... below is a summary of our brainstorm:
-Change over time
-"we evolved from monkeys"... NOT TRUE!!! we shared a common ancestor with monkeys!
- Darwin is credited for 'natural selection' and 'survival of the fittest'
- Evolution is a THEORY, not a LAW.. but it does have a lot of evidence

We then started a movie about Darwin's voyage.

A Timeline of Life

ARIANA will be our next scribe!
For Homework... nothing is due tomorrow, however, you need to do a DOUBLE BUBBLE MAP titled "Darwin v. Lamark" using the readings from 16.1, 16.2, and 16.3.  It is due Weds.  Be sure to do a good job of including specifics IN YOUR OWN WORDS! See moodle for help with the format.

Also, come visit Mrs. Stein for a HW pass before next Tuesday! 

Lets all get off to a good start! 

Secret Scientists Are Making It Rain!!!

so on the gold thing we filled out today i metioned scientists making artificial rain in the Rub-al-Khali desert also known as the empty quarter for being so dry and hot...baisically of all the places you could get stranded try your besst not to get lost there.. k? k.

here is an article if you are interested :
http://www.aolnews.com/2011/01/10/secret-scientists-claim-to-create-rain-in-arab-desert/

if you google it then you'll see that they've done it in other areas as well but I think that making it rain in the "empty quarter"

p.p.s. buena suerte con los examens finales :)

TEST REVIEW!!!!!!!

Here are some review questions that will hopefully help with studying :)

Q: What is the importance of the reproductive system?
A: It is important to the survival of a species and it may increase genetic variation.

Q: Describe the difference between Asexual and sexual reproduction and give examples.
A: Asexual is when there is one parent and the offspring is a clone. Some examples are, bacteria, plants, and other simple organisms. Sexual reproduction is the joining of gametes which increases genetic variation. Some examples are, plants, and many animals.

Q: What are the different male reproductive parts? Describe them.
A: Testis is the site of the sperm production that produces chromosome testosterone. The scrotum contains the testis maintaining the temperature at below body temperature. The Epididymus is the site where the sperm mature and the Vas-derin carries the sperm from the testis to the urethra. The Urethra carries urine and sperm out of the body. The penis is an external reproductive organ.

Q: What does testosterone cause?
A: Muscle growth, pubic hair, broad shoulders, and facial hair

Q:What are the female reproductive parts? Describe them.
A: The ovaries contain the follcies where the eggs mature and where hormones are produced. The Fallopian tube is where the egg travels down and into the uterus . The urethra tube carries urine from the bladder to the opening to the entrance of the vagina. The oviduct carries eggs from the ovary to the uterus where fertilization occurs.

STUDY THE PICTURES IN YOUR PACKET FOR MORE INFO ON THE REPRODUCTION PARTS!

Q:What is internal fertilization and external fertilization?
A: External is where the gametes join outside the body where you need large number of gametes and water. Internal is where the gametes are joined inside the body where you need specialized organs and mating rituals.

Q: What is ectoderm,mesoderm, and endoderm?
A: Edoderm-living of digerstive, roproductive, and repiratory system
Mesoderm- muscles, blood, and the bones
Endoderm-skin and nervous system

Q: Describe the positive feedback loop.
A: The ovary releases low levels of estrogen which stimulates the hypothalamus to release hormones to the pituitary glad which gives off FFH to the ovary.

Q:What is the difference between Amnion and the Chorion?
A: The Amnion develops into the amniotic sac which cushions the fetus and the Chorion is a membrane in mammals to develop the placenta.

Q: What is Tubal Ligation?
A: getting the fallopian tubes tied to prevent pregnancy

Other things to know for the test:

Endocine system- Regulates bodily function and maintains homeostasis and it signals secrete hormones into the bloodstream

Hormones- chemicals released into the bloodstream (ex. Estrogen)

Pituitary glad- secretes nine hormones and regulates other endocrine glands

Other things to help prepare for the test 2maro......Review pages in packet (19 &20)

Homework:
STUDY FOR THE TEST WHICH IS 2MARO!!!!!

The next scribe will be..talkative TAYLOR! lol

YIKES I ALMOST FORGOT I WAS THE SCRIBE!!!!!!!!!!!!!!

Hello fellow class mates! Today in Bio we had a pretty funn day!=)

First off we started class by handing in our Flow map from homework over the weekend, and we took out our UP pgs. 19-20 that was also asigned for homework due today.

The first epidemic thing that we completed in class was when Taylor was asked to explain what FSH and estrogen does to the body, When David and Jacob continued to mess with her they had to answer the question



No Jacob Etrogen does not make babys i'm sorry='(



Then Sarina told us that it really makes the utirine lining fill with blood. WAY TO GO SARINA!!!!!!



After completing that we went through UP 19-20 and asked questions and went through the answers up on the smart board



Then we toke some notes off of a power point about Pregnancy and Development and Contracepion. OHHHHHHHHH=)



FINALLY Mrs S. told us all a story about how she found out she was pregnant, It's pretty cool you should ask her if you havn't heard it!



HOMEWORK FOR TONIGHT IS TO STUDY FOR FINALS AND FOR OUR QUEST ON WEDNESDAY!!!!!!!!



Next scribe is TARA!

It's the weekend

On Friday we learned about Fertilization and Implantation. We took notes and discussed this in class. Then we had about 30 minutes to work on lab 31. The notes were:

-Fertilization occurs in the oviduct

-Zygote-a fertilized egg, diploid cell

-Cell division begins

-embryo-more than 1 cell

-morula-solid ball of 64 cells

-Blastocyst-hollow ball of cells

-Embryonic Development

-gastrulation is the formation of 3 embyronic germ layers

-endoderm -lining of digestive, reproductive, and respiratory systems

-mesoderm- muscles, blood and bones

-ectoderm- skin and nervous system



The homework for the weekend was to do pages 19 and 20 in the U.P. and to read 34.4 and do a flow map



Have a good weekend, the next scribe is Briget N!!!

hey so it's thursday :)

Today was...ineteresting... first we finished the puberty myths and then we got on to the topic of douches and how they actually increase chances for infection...but then we got on the topic of why people call other d-bags( yeah that happened)..it was actually pretty funny... but if you didn't know what a douche is it is a squirt bottle or bag that women use to clean their vagina...Then after we talked about birth control and how pregnancy tests work and I'm going to attempt to summarize sort of how it works.. here it goes... So when you are preggo there is a special hormone that is present in you're urine and it only releases when the ovary is fertelized so the stick that ladies pee on is testing for the presence of that...i hope that's correct cross check with mrs.s if you want a more accurate answer and you're really curious...

In other news we had the reading check and we took some notes...and started annotating Lab 31.
The homework:
1)annotate lab 31 due at the end of class on friday but DO NOT slack off because we only get thirty minutes and you could be doing other productive things in those thirty minutes like studying for the bio final (smart idea since you can ask mrs.s questions)
2) watch online links on the menstural cycal (they're on moodle)
3)Review pages 992+993
4) test / quiz on wednesday
I don't think the notes are on moodle..and I left my notebook at school :/ so get them from a friend if you need to..sorry

the next scribe is Sam :]

p.s. i like to check the vistor location thing...kaycoolbai ;)

Halfway through the week!!!

Today in class we started out by talking about yesterday which was bio day. The movie that we watched talked about how a baby was born. It took us from how it was conceived to the moment where the baby was born...in great detail.

We cotinued the day by reviewing the notes that we took yesterday about reproduction and developement in animals. How some species fertilize and develope externally and others internally.

Then we corrected our homework that was due today (UP 5-8). Which was about the reproductive structures of male and female. After that, we took notes on male reproductive structures and the male secondary sex characteristics. We started on the female reproductive structures but then decided to finish the rest tomorrow.

We went on to do the puberty myths worksheet. Which had some pretty interesting facts. Some of the true ones were: women can swim while they are menstruating, erections can happen in male babies, and warm baths may relieve menstrual cramps. There were many false ones and some of them were: Women are the only ones responsible for birth control, only older women can use tampons, and teens sledom get STDS.

Homework:

Read 34.1 and 34.2-not all, check moodle for the pages that is suppose to be read
There is a reading check tomorrow so be prepared for whatever it is that she gives us.
There is also a 'quest' on Wednesday.
The next scribe will be....Saadia.

Reproduction

Today in class we first looked at Mrs. Stein's wonderful blog about the new year. We also saw some great pictures of her son Max. After that we shared our fascinating stories. That was very fun! We eventually received our tests back that we took right before the break. The scores were scattered across the board and ended up learning about how grading curves work. This was all very fun.... but the highlight of this class had to be the video we watched. It went into great detail about all different animals and how they perform sex.  Some of this was pretty graphic. The most unusual technique was probably the dragonfly's. This class was a whole lot of fun and I learned a lot! We will be learning a whole lot more about this subject tomorrow in our Bio Day! I'm Looking forward to it!  Here is a picture....

The Homework was...

UP 5-8... label diagrams AND describe functions

Our next scribe will be.... Angela

HAPPY NEW YEAR!

Hope everyone had a wonderful and restful Winter Break!  The next two weeks is going to FLY by... finals will be here before you know it!  To help get yourself ready for finals, get your materials from your classes organized SOONER than LATER.  Figure out what material is the hardest for you and start there... so you have time to review that material more than once before the exam.  We are going to do one more short unit before finals... we will learn about reproduction and hormones. 

Our next scribe is... DAVID
