February 1, 2011 - SNOW DAY TOMORROW!!

Agenda:

• Show Mrs. Stein UP 26 (the endangered animal sheet) plus the "Picture This!" homework
• Enjoy Matt's post and it is revealed that I am to be the scribe today
• Evidence for Evolution Quiz
• Discuss and grade quiz
• Lab 38

We started off the class period by showing Mrs. Stein our UP 26 and Picture This! homework and received a homework stamp sheet. Then we were handed back our breakfast for birds lab (UP 4-8). We then spilt into partners or worked by ourselves and did a Evidence for Evolution quiz on such terms as Homologous, vestigial and analogous structures. We then graded our quizzes in class and took a few notes on the terms:

Comparative Anatomy- the study of similarities and differences between species' bodies.

Homologous Structures- similar bone structures

Comparative Embryology- examine and compare embryos of organisms

Analogous Structures- different organisms began living in similar environments, their appendages evolved to perform the same function.

Then we did "Lab 38" which is located in our biology lab books. Mrs Stein explained how we have to color the bones in the animal diagram and then answer the questions. We finished off class by finishing the lab and hearing how the travel advisory for today was "life threatening" from Mrs. Stein.

Homework:

• finish the lab
• Read 19.2
• T.V. ad 2/28

Snow day on wednesday so all the homework except the t.v. ad is due on thursday.

our next scribe will be...... Amanda!!!!

Bio Day Tomorrow!

Agenda:
Hand in UP pages 4-8
Look at Delia's scribe!
Go over green sheet for homework
Work with class on UP page 13
Discuss natural selection lab UP pages 17-19
Engage in superduper fun natural selection lab UP pages 17-19

Today's class started off by handing in the unit packet pages 4-8. We then took a gander at Delia's scribe which then left me with some tragic news at the end. Anyway, after that Mrs. Stein went over the green sheet that goes along with 16.4 for homework. We then worked briefly on page 13 in the unit packet as a class. We had to tell whether the sentence went along with Darwin, Lamarck, neither or both of their theories. After, Mrs. Stein then described to us what was needed to do for the natural selection lab. (UP 17-19) Finally the class split up into their groups and worked on the lab. The natural selection lab shows how the environment determines what species survive and which ones die out. In this case the dots who camouflaged with the cloth were the ones that survived.

Today's Homework:
UP 17-19 and chapter 16.4 w/green sheet - Due Monday
TV ad - Due 2/28
Visit Mrs. Stein for a homework pass!

Bio day tomorrow, meet in the auditorium!!

The Next Person to recieve tragic news (scribe) will be...Susie!

.....Dreams do come true.

Agenda

Hand in double bubble map

Finish discussing Darwin

Breakfast for Birds

Today class started off by everyone handing in their double bubble maps.

We took notes about Darwins Assumptions, Variations, and Descent with Modification.

Darwins Assumptions

(based on his observations)

- Over production

* More offsprings are produced than will survive.

(For ex: producing a lot of eggs)

-Struggle for existence

* Predation and competition

-Survival of the fittest

* Individuals best suited to the environment will survive, reproduce and pass on the traits to their offspring.

(Meiosis- genetic variation gives natural variation)

-Variation

* Differences among members of the same species

-Descent with Modification

*Principle that species change but descend from common ancestors.

After note taking we began a new lab.

Mrs. Stein gave us all a brief understanding of our lab BREAKFAST FOR THE BIRDS.

-There were five stations

1) Log (rice)

2) Pond ( foam pieces)

3) Field (sunflower seeds)

4)Rocky ledge (staples)

5) Worms in grass (rubber bands)

At each lab station there were pliers, forceps, spoon, and a staple remover ( one of each tool).

Each person used ONE tool to collect as much "food" as they could with that tool. Each tool represented the beaks of a bird.

At the end of each session each person had to count how much "food" they collected with their "beak" (tool) and the group had to collect their data as they moved around to each station.

After the lab was completed Mrs. Stein explained our homework (the graphing part of it).

It was simply graphing your data onto a bar graph to analyze and compare the results.

Homework

Up 4-8

See for hw pass- Tues

Tv ad project- 2/28

Next scribe will be Matt

Today in class Mrs. Stein started off the day by speaking to us a little bit about our newest project on endangered species! More information can be found on the project on page two of the newest biology packet. Then, we all took some notes on Jean Baptiste de Lemark and Charles Darwin.

Jean Baptiste de Lemark

*First to recognize that organisms change

*theory was disproved

3 key assumptions;

-desire to change
-law of use and disuse
-inheritance of acquired characteristics
Charles Darwin
*Created for the theory of evolution
*HMS begle sailed in 1831-galapagos islands
*published origin of species in 1858
Darwin’s observations;
*observed tortoises, iguanas, and finches.
*The islands had different climates and vegetation

*animals were similar, but had noticeable differences.

After taking these, awesome and utterly interesting, notes we continued watching the video on Charles Darwin’s adventure to the Galapagos islands. Just before leaving the room, I fortunately remembered to copy down the homework. This concluded the class period of Tuesday, January 5th.

Our next scribe will be Delia!
Homework;
1.double bubble map-tomorrow  “Darwin vs. Lamark” use test sections 16.1, 16.2, &16.3
2. Visit Mrs. Stein by Tuesday to receive homework pass
3.TV ad 2/28

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 that was hosted by Alan Alda... the dude from MASH!



Timeline of Life!

Holly 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!
