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.

11/1/10 Blog
Hellooo period 8 Bio-ers! Here is a recap on what happened today.
1) Mr. Paek talked about a new project: A post card to sent to your technology hating grandma Gurtrude about a new virus epidemic (you choose what one) and send a post card telling her how to prevent it. Look on UP page 2 for more information.
2)We finished the bacteria lab that we started last Friday by checking the petri dishes and seeing the growth of the bacteria that grew. According to some people, it smelled bad....but whatever. Then you finished the remaining questions about the lab.
3)Third and Finally, we watched a BILL NYE THE SCIENCE GUYY video about bacteria.
Annddddd thats about it!
REMEMBER: THE POST CARD IS DUE NEXT MONDAY!
HOMEWORK: 35.2 NOTES!

4.2 Niches, and Community interactions
Chapter 4.2 Niches Community interactions
First question, whats a niche? A niche si when organisms live in different places so that the organism can live according to its needs. The conditions define how and organism will live and where it will live
Every specie has its own tolerance level. Tolerance meaning the ability to survive and reprodouce under a range of enviromental circumstances. Basically, it means what an animal can live in that good for its needs. If something in its enviroment changes, like a rise in temprature, the organism or animal starts to become stressed. When it becomes stressed, it has to use more energy to keep homeostasis (maintaing internal stability), thus, having less energy to grow and reproduce. Organisms have an upper and lower tolerance limit, but go beyond the lower or higher tolerance limit, and the organism will die.
An organism's tolerance level will define its habitat, or "adress" of where it lives.
To follow up on Niches, a niche not only describes what an organism does, but how its reacts with living and non living things
Other things about niches
-Resource can mean any nessecity of/for life (light, food, air, etc) Resources are needed for a niche to survive.
-For the physical aspects of a niche, the weather/climate has to be ideal for the organism to live in the niche.
-The biological aspects of a niche is the biotic (living) features that it needs to live.
In niches, competition is a big part of life. For example, plant or tree roots might compete for rich soil and water. Competition happens when two organisms try and use the same resource at the same time. A winner and loser is produced everytime theres competition, then the organism that lost dies out. Theres a principle called the Competitive exclusion principle that says that no two species can occupy exactly the same niche in the same habitat at exactly the same time.
Sometimes, organisms/species will even split up, or divide the resources.
All animals must eat other animals to get the nutrients and energy they need. Predator and prey relationships are when a predator hunts and feeds on the prey, this is called Predation.
There are also herbivore (plants) relationships where the animal eats only plants and vegitation.
Changed in population or a single specie is called keystone species. And that can make big changes in the community it lives in.
Symbioses is any relationship in which two species live closely together. And there are three main classes of symbioses.....
1)Mutualism: when both species benifit.
2)Parasitim:A relationship when one benifits when the other is harmed
3)Commensalism: Where one benifits and the other is not harmed.
And thats the 4.2

Tuesday 8.31.10
First, Mr. Paek talked about the microscope lab that we were going to be doing later on in the class and finishing on Wednesday. He also talked about the “quest”(quiz/test) we were going to have on THURSDAY about microscopes and making graphs.
Second we looked in out UP (unit packets) page 33 and it was about the microscopes (compound) were going to be using. Then, we were taught the do’s and dont’s of handling a microscope. Such as
1. Start with the lowest power (smallest lens) then work your way up to the strongest.
2.Mr. Paek talked about how the microscope lens and how the eye piece already magnifies whatever you’re looking at by 10 times. (pg 41 in packet)
3. And the different types of various knobs that moved the stage, focused on what you’re looking at, or made it more defined. And the knob that lets more light in to see your slide.
The class got into groups of 2-3 and started the lab, looking at a lot of different slides, such as; a wet mount slide with pond water, a wet mount slide also but with yeast culture, and another wet mount slide with a fish scale.
Taking out the microscope, and making the wet mount slide (that we learned how to by putting whatever you’re looking at on the slide and putting a drop of water on it, then putting a plastic cover over it) and then drawing a colored picture about what you saw, then answering questions that corresponded to what you just looked at.
When you were done with the mandatory slides to look at, turning to page 39 in your UP, and getting a dollar bill from either Mr.Paek of your own, you looked at the dollar bill with good ol’ George Washington’s facing you, then answering the questions on the page.
We didn’t have time to finish the lab, so that was all we got up to for today.
