NEW UNIT (:

Today, we started a new unit about the animals, but first, Mrs. Stein gave us grade reports and we saw what we got on the Evolution Test. She told us that we got a good head start on the new semester! After that we had a POP QUIZ on 18.1 **she sort of told us there would be one.** 18.1 was about classifying species and the order of diversity. Once we took the quiz, we took notes on the Animal Of The Day #1. We took notes on a hagfish, which is a slimy, eel like fish that has survived for millions of years. Then, Mrs. Stein introduced to us the Profile Project, where we are going to be invertabrates, an animal without a backbone, and we will create a profile. The project can be found on UP 3. Then, the learning came, and we took notes (:

PEOPLE ALL OVER THE WORLD HAVE SEEN THIS BLOG!

Just for entertainment, look at the map and look at how many people have looked at our blog!! It's kinda cool, isn't it!

BUCKTHORN EXPERIENCE

Yesterday, Anastasia and I were a part of the North Branch Restoration Project, and cut buckthorn at Harms Flatwoods. When we got there, we signed in and went went to the west side of the forest preserve to cut buckthorn. With us were normal volunteers and also students from New Trier. The person in charge of the group told us that buckthorn was being a problem in that it surrounds native trees like the oak tree and doesn't allow them to reproduce. He told us that whatever was green, was buckthorn. Buckthorn was the only plant still standing with its leaves, so it wasn't hard to miss. When me and Anastasia got to the site where we were going to cut buckthorn, we saw SO much of it! It was everywhere. It was taking over everything else. When we went inside the forest preserve, we took a clipper and we went and cut buckthorn, while the experienced people were putting up controled fires so we can burn the buckthorn. For some odd reason, this computer isn't leting me upload the pictures onto the post, so see Anastasia's. SORRY.

Anyways, Anastasia and I thoguth we'd be cold so we dressed up so warmly, and when we got there, with the four fires and the hard work, we were dying of heat. It was pretty interesting in that me and Anastasia helped the forest preserve from this invader, buckthorn. It was a lot of fun, and I would do it again any time!

STUDY STUDY STUDY!!

Today we started class by turning in our homework, which was the postcard to Grandma Gertrude and UP 32 and UP 37-42, and to read 35.4 by tomorrow. After we finished the tree map on the Immune System, the acquired immunity branch.

In acquired imunity, you should know that it can either be active or passive. Active immunity means that the body makes the antibodies. An example of active immunity is vaccines or exposure to the disease, and active immunity lasts for a long time. Passive immunity means that the antibodies are obtained passively. An example would be breast milk or injections of antibodies. This is more temporary than active immunity.

After, we got the chance to ask Mrs. Stein questions because, we have a test tomorrow!! STUDY HARD EVERYONE!! It's going to be difficult considering there's a lot of difficult material covered in the test. Remember to go over the objectives page in the first page of your yellow UP packet.

The test covers pretty much all of chapter 35 and chapter 20.

Remember to review...

VIRUSES
-capsid, bacteriophage, prophage, retrovirus
BACTERIA
-prokaryote, bacillus, coccus, spirillum, binary fission, endospore, conjugation, and nitrogen fixation.

GERM THEORY, KOCH'S POSTULATES, VECTORS

IMMUNE SYSTEM
-non specific defenses
*first line defense: skin, tears, mucus, saliva, cilia
*second line defenses: inflammation, fever, histamine signals, and increase in blood flow and fluids

-specific defenses:
Humoral immunity: B CELLS (antibodies)
Cell Mediated Immunity: T Cells (attacks your body cells)

REVIEW ALL LABS

LOOK AT DIAGRAMS AND PICTURES MRS. STEIN GAVE US

Please, please, please make sure you understand the objectives page, if not, go to the review session tomorrow morning!! GOOD LUCK TO EVERYONE!!! :)

The next scribe is...Anastasia :)

Population Density Lab

On Friday, in Science we started by asking questions about the Alien Species Project and about then wrote our homework, which is below. We then spent our class time outside and started the LAB 58. The point of this experiment is to learn more about population densities. Mrs. Stein assigned each group an area, and then each group set up a “quadrat” of 1 square meter, so each group basically isolated one square of 1 meter squared from the rest of the grass. Then, each group had to separate the squared area into ten sections, each ten centimeters apart, and start counting how many plantain plants, how many dandelion plants, and the number of clover plants were present in that particular area. Then, the group would total up their numbers of each plant.

Below is a dandelion like the ones we counted.

In the mean time, Mrs. Stein called us up and told us our grade on the last quiz; that is if we wanted to know our grade. Then, we went to the classroom, and we shared our data. The class data was that there were 176 dandelions, 95 plantains, and 236 clovers. Class ended by telling Mrs. Stein what animal one wanted to research and do his/her project on for the Alien Species Project.

Remember, on Monday, our period 2 STS Biology class will be meeting in the IMC.

The next scribe is Anastasia M.
