Force part two
We also discussed the idea of the mass or massiveness. Mass is the amount of matter that is consisted in a substance.
Mass is what gives us weight. It is because the mass of a substance is pulling down on us, that of force that is pulling down on us gives us our weight!
In space, there is no gravity until we come close to a huge mass like the moon or another planet. So, if we launch a rocket into space, the rocket will stay in the course that we put it in. Then the rocket will start accelerating toward a mass because of the mass' gravity is bulling down on the rocket toward the mass. So eventually, with the gaining acceleration of our rocket, the rocket will crash into the mass.
Since the moon has a lesser gravity than the Earth, the moon will have a less pull on the objects near it. Or less gravity in the objects near it.

Force

This week in science, we learnt that there is something that makes things and us move. and that is force. Force is a push or a pull on a object.

Science
There is a simple pneumonic that can help students remember the organization of nature:Kangaroos Play Cellos, Orangutans Fiddle, Gorillas Sing.
If we take a Ring-tailed Lemur, we can trace it through the hierarchy of nature, taxonomy as follows, it belongs to:
The Animal …Kingdom
sharing with all other members of this group the need to feed on organic matter (unlike plants which can create energy using light and minerals)
The Chordate (or vertebrate) … Phylum
sharing with all other members of this group of animals, a back bone with a hollow nerve chord
The Mammal … Class
sharing with all other members of this group of vertebrates, the ability to feed their offspring on milk and having a body covering which includes fur
The Primate … Order
Sharing with all other members of this group of mammals, a thumb that can be opposed to the other digits, binocular vision and various more broadly defined characteristics (including high intelligence, relatively long maturation period for the young, dental similarities, tendency for complex social organization, and generally bearing one or two young)
The Lemuridae … Family
Sharing with other members of this group of primates, a slightly longer nose, smaller brain, long slender limbs, a tail, more specific dental features including the grooming comb formed by the lower incisor and canine teeth
The Lemur … Genus
Sharing with other members of this group of lemurs, scent marking methods, vocalizations, aspects of social structure and overall body shape
The Ring-tailed Lemur … Species
I have to cite this: http://www.tigerhomes.org/animal/curriculums/lemurs-4.cfm
Just like that, we are classified live this:
Kingdom: Animalia 
Phylum: Chordata Class: Mammalia
Order: Primates
Family: Hominidae Genus: Homo
Species: sapiens So, we are classified as Homo Sapins. Thi s is the most dynamic way of saying what we are.

Cockroaches!
Friday, April 10, 2009
1)the mud in a bog is full of tanning acides that when a man was thrown into the bog, then picked up 1000 years later, th ebody was fully preserved but the body was tanned like leather.
2)When you are out in th ewilderness, and it is cold. You do not have any thing but sticks to build a shelter, build a shelter low to the ground. this will thake your body heat and warm the small area that you are in.
3)Salamanders breathe from their skin!
4)Cratures that live in a stream have a stronger body/aerodyminicle body to fight the current of the water.
5)When a stromg wind is coming,and you have a high structure, the wind could snap the structure in half. Tha tis why you should put holes in the building so the air passes through the building

Genetic Variety in Reebops

Monday, March 9, 2009
This week in science;
(Exp.---white flower*Red flower=Pink flower.
This is a really cool site that told me a lot about incomplete dominence:::
http://www.hobart.k12.in.us/jkousen/Biology/inccodom.htm
The next day, i got a migrane and had to miss the first 4 periods of school, so this is what i learnt from that day:when you have 2 dominance for a trait, it becomes a co-dominant. This happens in blood when there is two DOMINANT blood types mixed like A and B (AB).Then on top of that, there is the proteins that attach on to the blood types.(positive and negative.) The positive always is the dominant one.
I don't know what happened the rest of hte week in science.

On Wednesday, we went over some of the things about Genetics. Then Finley told us some things about the Lab that we will be doing th enext day. We created "egg and sperm cells for the experiment."
On thursday, we learnt that the Genetic Mutation always results in the strand mutated becoming the Dominant Gene.
On Friday, we did the experimen of mixing uop sperm and egg cells and looking at what the outcomes would look like. Then we had a quiz that we had to do at home whch I just hot to see.
This is what tje quiz was
Spiderman and Spidergirl got married and soon found out that
Spidergirl was expecting a son. Spiderman couldn't wait to
welcome his new son into the world and was looking forward
to fighting crime with him. However, when he was born
Spiderman realized that his son does not have his parents'
"spider" quality. Spiderman believes that the baby might
actually be Batman's! (Remember, Batman has ZERO special powers)
What do you know about the "spider" trait?
What could spiderman and spidergirl's genotypes be?
Did spidergirl have batman's baby? Support your answer with an explanation
Hard Quiz.

Science
A homozygues is a species that has the same trate from the mom's side and the Dad's side.
A hetrozggues is a species that has two different trates. One from the Dad's side and one on the mom's side.
The recessive trait is always the trait that does not take over unless there are two rrecessive traits, which makes it a homozygues.
If hter is a dominent gene and a recessive gene, the dominent gene always takes over.
This is a great video that i found that helped me understand Genetics.

Meiosis
The first stage of meiosis is:
Interphase I: Whe the cell goes through its normal life.
Prophase I: The centrioles pull apart the one
Metaphase I: the chromosomes or homolagues pairs line up on the metaphase plane and are ready to be seperated by the centrioles.
Anaphase I: During anaphase I, the cell's spindle fibers pull the chromosome pairs and start to go to opposite poles.
Telephase I: During telephase I, the cell's nucleas starts to reform and th edaughter cell's nucleas also starts to reform and finishes to reform.
Cytokinesis I: During cytokinesis, The cell's membrane reforms and there are two indevidual cells now.
Meiosos II
Interphase IIDuring Interphase two, the cell's centrioles come and surround the nucleas and start producing spindle fibers.
Prophase II: (Interphase II)
Metaphase II: During Metaphase II, the cell's chromosomes line up ready to be seperated.
Anaphase II: During Anaphase II, the cell'schromosomes are pulled apart just like meiosis.
Telophase: During Telophase II the cell's membrane starts to close off creating 4 new cells. Then the nuclear membrane reforms.
Cytokinesis II: During cytokinesis II, the cell's break off from each other creating 4 sperm cells.

Mitosis(Cell reproduction)
On monday, we talked about the things that happen mitosis and the stages/phases that occur during Mitosis.
Interphase-the phase that the cell stays in and when the cell copies the DNA/chromosomes for reproducton.
Prophase- Is when the nuclear envelope wears away exposing the sister chromotids.
Metaphase- When the cell's centrioles use the spindle fibers to pull apart the sister chromotids.
Anaphase- Is when the cell's centrioles seperate the sister chromotids and go to the other ends of the dividing cell.
Telophase- Is when the cell's nucleas starts to reform in the prexisting cell and the daughter cell just created.
Cytokinisis-Is when the cell's membrane reforms around both the parent cell and the daughter cell and the cells are now no longer dependent on eachother and Mitosis ends.
Then we had a Quiz on that stuff

Science
On Tuesday, we reviewed for the teas on Tuesday by watching a video on how our skin and body is crawling with living organisms. On Wednesday, we had the test on The things we learnt on cells before.
On Thursday we looked at cells under the microscope to learn about mitosis, which is when cells reproduce.
On Friday, we went to a website that shows the different stager of mitosis and did a workshhet on it. Here is the website: http://www.cellsalive.com/mitosis.htm.

Science This Week
This is a website that shows an animation of this:http://www.cellsalive.com/mitosis.htm.
We also learnt how mRNA gets translated by the ribosome. This is a good show to go to that will explain how transcription and translation takes place:http://www.youtube.com/watch?v=nl8pSlonmA0
Thursday, January 8, 2009
During the week in science, we did a lot of things.Here is what we did;
We learnt how to decifer DNA and RNA reading. this is an image of RNA being translated by a ribosome.
Below is a website that explains mRNA translation.
http://www.biology.iupui.edu/biocourses/N100/2k3ch13dogma.html
When a cell needs to make new proteins, it sends out a part of its DNA called RNA. That Messenger RNA goes to the ribosome that is on the outside of the nucleas and gets read by it. The ribosome then creates the proteins that the mRNA told it to make. Those proteins then go to the golgi apparatus to get sent to the part of the cell that needs
it.
We also learnt why a fish cannot survive out of water.This is how: When a fish is in the water, the fish's gills filter out the water and other chemicals in the water. Then it only allows the oxygen to get into the fish so the fish could breathe.
If the fish was out of the water, the fish would not be able to breathe because the gills of the fish cannot filter the other gasses in the air and only let the oxygen in. Therefore the wish will suffocate to death.
