Happy Wednesday!!

Today we started class with our third animal of the day. It was called an Axolotl. Its in the class amphibia. What makes this animal different from a lot of other animals is that it does not go through metamorphosis.Next we looked at an evolunary tree. This shows organisms and how long ago they had a common ancestor.

We learned about radial and bilateral symmetry

bilateral symmetry - is when a single imaginary plane divides the body into left and right sides that are mirror images of each other.

radial symmetry - is when any number of imaginary planes drawn through the center of the body could divide it into equal halves.

Homework: Green chart due friday! (use DOT pages 30-45 in the back of the book)

read sections 26.1 and 26.2 don't forget profile due feb. 22 and t.v. add due feb. 28

LAD THURSDAY!!!

Today we worked on two labs one on pages 19 through 27 and the other one starts on page 14

on page 14 we have to identify the different animals in the different jars. All you have to do is look at the key on page 13 in the unit packet and figure out which phylum each organism is in. The second lab we went around to 8 different stations and answer the questions. some of the answers will be in our biology book and some answers will be in the book from last year. we also got to see a live centipede and learned the differences between a centipede and a millipede. Another interesting thing we experienced today was hearing a cockroach hiss.

homework: finish the two labs pages 14 and 19-27 due on tuesday

Green chart due tomorrow

profile due feb. 22

t.v. add due feb. 28

Tuberculosis Tuesday!!

In Class:

First, we handed in our labs which was pages 13-18 in the unit packet. Next, we started learning about our disease of the day, which was tuberculosis. The agent of this disease is bacteria and is spread through the air. It infects the lungs and then is spread it brain, kidney, and spine. Also, there is alot of antibiotic resistance. Then, we took some notes on antibiotic resistances and how much mutation and conjugation can make bacteria resistant.

This picture shows hows the pump can shoot the antibiotic out of the bacteria and other ways bacteria can be resisted.

HOMEWORK:

Postcard- Due November 8th

Test- November 9th

BP Oil Spill and How its Affecting the Tourism Industry By: Samantha and Gabby

Back to Biology!!!!

Our first class of the week was on Tuesday. We began by handing in our 3.1 and 3.2 cornel notes, then we picked up a diagram of a food chain. As we were taking notes, we learned about trophic levels which are each different stages in a food chain. We also learned how all energy that comes from the sun turns into energy for producers which then transfers to the consumer. We wrote down all the different categories that the plants and animals fall under they are: scavengers, decomposers, detritivores, omnivores, carnivores, herbivores and primary pruducers. You will find all of those and more in the notes you took in class.


Homework: RIP-O-METER LAB WRITE UP due wednesday!! dont forget it must be typed! Also read section 3.3 and complete picture this notes. (if you forgot how to do the picture this notes just look on moodle or you can also find how to do them in your blue packet.) Today was the last day for a homework pass but you have another opportunity to get one by going to the TLC before ,after or during a free period and working on biology for at least 30 minitues. You also have to get the card signed by a staff member in order to turn in the pass to Mrs. Stein.

Remember , we are going to be starting a project so start to think of ideas or opinions you have regarding the oil spill.

Our next scribe will be Hannah
