Announcements-Quiz tomorrow on Phylums, know the characteristics of each phylum and examples for each phylum.

Homework-Study for tomorrow's quiz and work on the T.V adds.

Today in class we began by learning two new animals of the day:

Animal of the day #4 Dumbo Octopus

Phylum: Mollusca

Grows up to 20 cm

Have ear-like fins at the top of their bodies

Lives in the benthic zone, living at extreme depths

Status: not considered to be endangered

Animal of the day #5 Frill-Necked Lizard

Phylum: Reptilia

a.k.a."Frilled Dragon"
1 meter in length
Large ruff of skin supported by spines of cartilage, exposed when scared
Frill might help with thermoregulation
Runs bipedally, often climbs trees to avoid predators



After we finished going over the first two animals Mr. Paek showed us a video of a lizard nicknamed the Jesus Christ Lizard because of its ability to run on water.



We then took notes on the Phylum Arthropoda before beginning our lab. The notes said that Arthropoda are jointed leg animals with four classes
1:insecta-insects
2:arachnida-spiders, tics, etc.
3:crustacea-crayfish, lobster
4:myriapoda-cenepedes, millipedes

The lab we did in class today was on pages 28 through 33 in the unit packet and it covered the Phylum Arthropoda. We split up into lab groups and each worked on the Lab while observing a spider, grasshopper, and crayfish that were dissected on the table in front of us. It was a very interesting lab.

We ended the day in our lab groups finishing the lab and for the next two days all the biology teachers are going away to a conference so we will have substitutes and remember, "BE NICE TO THE SUB".

The next scriber is Su.

Today in class, Mr Paek showed us a clip of the movie Stand by Me. When 4 kids are in the middle of the forest and they decide to go across a small lake. When they get out they discover that they are covered in leeches. Leeches are apart of the Phylum Annelida. They feed on another hosts blood. They often feed on humans blood. Without this supply of blood the leech will die.


After that Mr. Paek told everyone what the homework was and a few announcements. We are going to have a quiz on Tuesday about animal diversity. Mr. Paek said the best way to study for it is to know:

How To Study For The Quiz on Tuesday:

1. How to label a table with the 8 phylums.

2. Know 1-2 key characteristics about each phylum.

3. Memorize all 8 phylums.

4. Review the Unit 8A Notes Sheet.

Homework:

1. UP page 14, 19-27

2. Don't forget to start on the TV Ad. It is due March 1st

3. Quiz Tuesday



Right after that we finished up the lab, "Investigating Invertebrates". On UP pages 14, 19-27.

Station 1: Phylum Porifera (UP19)

This is an animation of a sponge.
















Station 2: Phylum Cnidaria (UP20-21)



This is a picture of a J\ellyfish

-




This is a picture of a flatworm

Station 4: Phylum Nematoda (UP22-23)





This is a picture of a Vinegar Eel

Station 5: Phylum Annelida (UP23-24)







This is a picture of an Earthworm.

Station 6: Phylum Mollusca (UP24-25)







This is a picture of an Octopus

Station 7: Phylum Echinodermata (UP26)

This is a picture of a Sea Urchin

Station 8: Phylum Arthropoda (UP27)

This is a picture of a Scoripion.

HOMEWORK:INVERTEBRATES ANIMAL PHYLUM CHART

In Bio today, we.....
1) We wrote down the animal of the day: Axolotol, and its in the Amphibia class.
2) We talked about Phylums, in the kingdom chart (no notes!). You would read the phylum chart by reading the animal name, then looking at the other animals branch off of it.
3)We worked on a green sheet about different types of invertabrates and they're types of locomotion, and unique characterists, etc. (It has to do with phylums) The pages are in chapter 26.1, but its easier to go to the apendix at the back of the book, 30-45. Thats the homework.
4)Also, with that chart, we learned about symmetry (Bilateral, radial)
5) We also took out leeches and...*shudder* cockroaches. Mr. Paek dropped a leech....twice. Also, a millipede was also taken out, but it wasnt that interesting.....

And thats it.

2-15-2011

Announcements-

Mr. Paek passed out grade sheets with the 2/11/11 evolution test grade. Mr. Paek took out all of the extra credit in homelogic because even if you got a D on your test, your grade will still be over 100. He wanted you to know your actual grade. But, he will put them back in your grades (homelogic) later when they will actually take effect.

Homework-

1.UP pgs 7-12 if you didn't finish in class ( DON'T DO #4 AND #5 ON PAGE 12)

2. read 26.1

Today, we took notes in the Unit 8A note sheet and filled out the section, Three Domain System, in the 2nd page.

Notes:

Three Domain System- larger, more inclusive than kingdom, recent addition to taxonomic structure. Based on comparing rRNA subunits.

1. Domain bacteria- unicellular, prokaryotic, corresponding to kingdom eubacteria

2. Domain Archaea- unicellular, prokaryotic, corresponds to kingdom archaebacteria.

3. Domain Eukaraya- consists of all organisms that have a nucleus, includes kingdoms, protista, fungi, plantae, animalia.

The animal of the day #2 is star-nosed mole. You only have to know that it is a mammal.

LAB

We did a lab today with a partner. UP pg. 7-12
Mr. Paek showed us how to do the classification key in page 5.

Classication key is like when...here are examples.

If you divided period 8's class into 2, you would separate boys against girls. Then, within the each 2 groups, you would then next separate again according to hair color and so on.

Another example is like saying "if it's this then go here" If the part,"If it's this", is true, then follow the directions on where you should go. It may be telling you a name and that will be your final answer.

UP pg. 5 (practice with Mr. Paek)

directions:

1. look at the first picture, A.
2. look at 1a and 1b and choose the correct fact as you look at the dog.
3. since it is a organism with two or four functional legs, go to 2.
4. look at 2a and 2b and choose the correct fact as you look at the dog.
5. since it is a organism without wings, it is a Canis familiaris (FINAL STEP)
6. you do the same thing for the other pictures.

the answers to this page are

ACFGDHEB

UP PAGES 9-12

DIRECTIONS:

The diagram tells you the characteristics of a shark so take #1 and put it in the key and find out the family each shark belongs to.

The next scriber will be Colleen

HOMEWORK: read chapter 3 in unit 18 (taking notes is recommended)

ANNOUNCEMENTS: The new unit packet is out! There also is a project due next week on Tuesday. You can find the project on page 3-4 in the unit packet.

*The Endangered Species Commercial is due in two weeks (Tuesday)

In other news, today I successfully ate some fried chicken throughout the span of class without Mr. Paek noticing (or, at least, caring enough to take away). It was a successful day.

There will be a lab on thu. and fri. featuring leeches so prepare yourself!

Animal of The Day: (a new daily thing) the animal of the day today is the Hag-fish.

type: agnatha, jawless fish

other features: the fish, when disturbed, sprays a slime which reacts with water, hardening into a jell-like substance. It's pretty cool, you can check out the Hag-fish in action at:http://www.youtube.com/watch?v=Bb2EOP3ohnE

notes: Taxonomy-def.: naming and classifying

Taxonomy groups:

-Kingdom: broadest grouping

-phylum

-class

-order

-family

-genus

-species: most specific

(those are groupings based on similarities of animals like: vertebrate vs. invertebrate, type of animal, ancestors, etc.)

"KPCOFGS" (Koo-pa-ka-fo-gus) is one way Mr. Paek remembers the order of the taxonomy groups in order of broadest to most specific.

Evolutionary relationships: based on biochemical similarities.

Binomial Nomenclature def.: 2 names comprised of genus and species.

Ex: Homo sapien (must be italicized, second word is lowercase)

Kingdoms:

-archaebacteria- comprised of prokaryotic cells

-protista- comprised of unicellular eukaryotic, heteretrophic, or autotrophic organisms.

-fungi- comprised of multicellular, eukaryotic organisms (like mushrooms and yeast)

-plantae- comprised of plants

-animalia- comprised of animals

-eubacteria- comprised of single cell organisms

And finally we ended the day with a movie about large bugs, we ended at a part where the host was trying to prove that there were very large dragon flies at one point but they died of leaving only the smaller ones. he did this by trying to prove that the large flies were not used to the sudden decrease in percentage of air in the atmosphere (thanks to developing fungi which released more carbon dioxide into the atmosphere) and therefore died of from not having enough energy to gather food and reproduce, thus, leaving the smaller dragon flies to survive (assuming, that's where he was going with his study).

And that was bio for Feb. 14th 2011 (and i apologize for any misspellings)!

Oh and before i forget, the next scriber will be Su.
