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

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.
