The Blog Post Of Wenesday, Febuary 9, 2011 (:

Today in class we first teared out from our book lab 40 but we didn't end up doing that lab so we could have time to answer test questions! BTW I'm really happy that we didn't do that lab becuase we had to do something with REAl and GROSS huge grass hoppers. soo yeah...

We then turned in UP 44-47 and we got our 26.3 notes stamped!

THEN.....we took notes!! (fun!!)

Here are the notes....

What is a Primate?
*Binocular Vision
*Developed brain
*long fingers and toes
*Rotating shoulders

What Make us Human?
*Characteristics of the Hominine Family
-Bipedal
-Opposable Thumbs
-Larger Brains

Hominine Evolution
*Ardipithecus ramedus, "Ard", 4.4 mya
*Australopithecus afarensis, "Lucky", 3.2 mya
*Homohabili, "handy man", -200,000 years ago
*Homo Sapien
-modern human- 100,000 years ago

After the notes we spent aome time going over the objectives part of our packet (first page of UP)
Some stuff we went over FOR THE TEST and some things you may have questons on.....

Homologous Structures- pretty much the same basic structure but with a different funcion but also made out of the "same stuff". example--- a whales arm and human arm

Genetic Drift- when a RANDOM group of individuals go off and start a new population (look at the diagram with the bottles and the blue and yellow marbles)

Gradualism- understanding that evolusion happened SLOWLY -bit by bit

Punctuated equilibrium- understanding that evolution happened fast and with a rapid change

aerobic- with oxygen
anaerobic-without oxygen


HOMEWORK:
TEST FRIDAY!!!!!!
TV ad 2-28

AND....we had a bio day on Thursday!!!

NEXT SCRIBE IS TAYLOR!!!

Happy Monday! (;

Today In Class
- Handed in Flow Maps
- Went over UP p
ag
es 33-36
- Watched a little clip of a Billy Nye video.

- M&M Lab!!!
(fun and yummy!)
Notes

Ancient Earth
  • Earth is about 4.6 billion years old.
  • Atmosphere was composed of gases: CO2, N2, water vapor, CH4, H2 S. (There was no O2.)
  • Oxygen came from plants.
  • Organisms in the past were aerobic. (didn't use/need oxygen to survive)

First Organic
Molecules
  • 1950's Miller and Urey reproduced conditions of ancient Earth.
  • Electric sparks stimulated lightning.
  • Amino acids began to form.


Miller and Urey's Experiment



ENODSYMBIOTIC THEORY
Homework

1. Finish M&M Lab UP 31-32. (tomorrow)

2. Read 26.3 w/ check my understanding (WEDNESDAY)
3. TEST FRIDAY! STUDY!!!!

4. Tv Ad dude 2/28


the next scribe is.......... Melissa! (;

Yayy Evolution!!!


IN CLASS:
-We went over the T.v add project (on page 2 of the packet)

-Began theories: Lamark/ Darwin

-Continued the video about the origin of species


HOMEWORK:

-Double bubble map due 2moro: Lamark and Darwin
-use text book chapters 16.1, 16.2, 16.3

-Make it detailed!!

-Visit Mrs. Stein for a homework pass due next Tuesday

-T.v add due 2/29


IN CLASS NOTES:
Jean Baptiste de Lamark

-first to recognize that organisms change

-published his hypotheses in 1809
-theory was disproved!



3 key assumptions: -desire to change

-law of use and disuse

-inheritance of acquired characteristics

Charles Darwin
-credited for the theory of evolution

-HMS Beagle sailed in 1831- Galapagos islands

-published origin of species in 1858


Darwins Observations
-observed tortoises, iguanas, and finches

-the islands had different climates and vegetation

-the animals were similar...but had noticeable differences


NEXT SCRIBE IS Jose!!!!!!!!!!! :))))) <3

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!
