“English: Another World - Diversity.

22nd July 2019



Diversity


What we have been doing in English in the last two terms.

We've been doing really fine with some topics that we didn't know yet which is interesting because I was kinda bit confusing it's challenging for me to struggle. We were reading books like all of us are literally just reading but you know we got the device that can only read for us instead of us reading a book like you can only use ur mind to read them or stare at it. Also, we had watching movies to learn of how they doing like viewing angles, world diversity, etc.
that makes me challenge a lot. Somehow I don't actually know what to do which really disappoint me a lot but I did my best to finish my task but I fail a lot, to be honest. And we did the (zootopia) made of cartoons or animations whatever you called that was fun and amazingly easy to know them.

It is best for me to know about diversity. Diversity means different cultural or diverse, like opposed to monocultural,  homogenization of cultures, akin to cultural decay. 

What do I already know?

what I know about diversity is about is people who are different to them should respect like their culture are different between us.

What did I learn this year?

I only learned some of the diversity which is in the book (the children blood and bone). Understanding their different perspectives and I actually respect them. I should respect the various culture based on diversity.

Aim: Turning copper into gold

Equipment:

Wire wool, five grams of zinc powder, beaker, Bunsen burner, gauze mat, tripod, tissue, beaker tongs.


Method:

1. Clean the copper with the wire wool 
2. Add five grams of zinc powder into the water 
3. Now turn on the bunsen burner to boil the solution.
4. Once the solutions are boiling then add the copper coin.
5. once the copper coin turns silver lift it out the glass beaker.
6. Now put the silver coin in some water to cool down.
7. Take the coin out of the water and dab it dry with a tissue.
8. Now take the coin using the beaker tongs and put it on the flame of the bunsen burner
9. flipping it occasionally.

As we were doing that, we had lots of fun doing this experiment of changing their colours which makes me satisfied with looking at it. As u can see the photo, we finally have done our experiment and If u tried it u might gonna like of doing that. Done!

How Sir Ernest rutherford "split" the atom

10th May 2019

About Ernest Rutherford:

His mother, who believed ‘all knowledge is power’, made sure her children had a good education.

After gaining three degrees at Canterbury College, Rutherford won an Exhibition of 1851 scholarship and used it to study at the Cavendish Laboratory of the University of Cambridge. Nicknamed ‘crocodile’ (because crocodiles always look forwards), he became known for his ability to make imaginative leaps and design experiments to test them.

In 1898 he accepted a professorship at McGill University in Montreal, returning to New Zealand briefly to marry Mary Newton, the daughter of his former landlady. It was at McGill University that Rutherford made the first of three major breakthroughs of his career: the discovery that atoms of heavy elements have a tendency to decay. This heralded the ‘carbon dating’ technique still important in science today.

Questions:

What school did Ernest Rutherford go to? How far did he go in his education? Why?

Ernest received his early education in Government schools. At the age of 16 he showed great talent so entered Nelson Collegiate School. In 1889 he was awarded a University scholarship to the University of New Zealand, Wellington. 1894, he was awarded an 1851 Exhibition Science Scholarship, enabling him to go to Trinity College, Cambridge. It is believed that Ernest received more scholarships that any other chemist. 

Is it possible to split atoms?

Researchers have just shown how a single atom can be split into its two halves, pulled apart and put back together again. While the word "atom" literally means "indivisible," the laws of quantum mechanics allowdividing atoms -- similarly to light rays -- and reuniting them.

How sir ernest rutherford "split" the atom?

Ernest Rutherford was the first person to knowinglysplit the nucleus, in 1918 at pManchester University where he bombarded nitrogen with naturally occuring alpha particles from radioactive material and observed a proton emitted with energy higher than the alpha particlel.

What did Ernest Rutherford discover about the atom?

In 1911, he was the first to discover that atoms have a small charged nucleus surrounded by largely emptyspace, and are circled by tiny electrons, which became known as the Rutherford model (or planetary model) of the atom.

How did Rutherford do his experiment?

Physicist Ernest Rutherford established the nuclear theory of the atom with his gold-foil experiment. When he shot a beam of alpha particles at a sheet of gold foil, a few of the particles were deflected. He concluded that a tiny, dense nucleus was causing the deflections

Did Rutherford discover the proton?

In 1911 Ernest Rutherford who performed many experiments to explore radioactivity did an experiment in which he discovered that the atom must have a concentrated positive center charge that contains most of the atom's mass. He suggested that the nucleus contained a particle with a positive charge theproton.

What did Rutherford think the atom looked like?

The atom consisted of subatomic particles called protons and electrons. However, it was not clear how these protons and electrons were arranged within theatom. J.J. ... Rutherford tested Thomson's hypothesis by devising his "gold foil" experiment.

Why did Rutherford use alpha particles?

The highly variable trajectories of the alpha particles meant that they did not all generate the same number of ions as they passed through the gas, thus producing erratic readings. This puzzled Rutherford because he had thought that alpha particles were just too heavy to be deflected so strongly.

English Introduce

In English we have been learning about
Short stories and poems, visual texts.
I think we are learning about this because we could listen while the teacher speaking , concentrated of doing some neccesary stuff about english and looking forward of it.

(Story) helped me to understand....

Pee wee

This movie makes sense alot. Anyways, this movie is a type of comedy. This guy nakes people entertain about his movement and the way he talks is so hillarious! This movie was about the holidays of how he moved on to his job and decided to go wherever he wanted after moving on. From that photo obvious that its a comedy, if u had watched this movie i bet you might gonna like.
At the wnd of this movie you wont stop

Investigate how to test for different blood groups

25th Mar. 2019

A blood sample is needed. The test to determine your blood group is called ABO typing. Your blood sample is mixed with antibodies against type A and B blood. Then, the sample is checked to see whether or not the blood cells stick together.

What Are the Blood Types?

Categorizing blood according to type helps prevent reactions when someone gets a blood transfusion. Red blood cells have markers on their surface that characterize the cell type. These markers (also called antigens) are proteins and sugars that our bodies use to identify the blood cells as belonging in us.

The ABO blood system has four main types:

• Type A: This blood type has a marker known as A.
• Type B: This blood type has a marker known as B.
• Type AB: This blood type has both A and B markers.
• Type O: This blood type has neither A or B markers.

Blood is further classified as being either "Rh positive" (meaning it has Rh factor) or "Rh negative" (without Rh factor).

So, there are eight possible blood types:

1. O negative. This blood type doesn't have A or B markers, and it doesn't have Rh factor.
2. O positive. This blood type doesn't have A or B markers, but it does have Rh factor. O positive blood is one of the two most common blood types (the other being A positive).
3. A negative. This blood type has A marker only.
4. A positive. This blood type has A marker and Rh factor, but not B marker. Along with O positive, it's one of the two most common blood types.
5. B negative. This blood type has B marker only.
6. B positive. This blood type has B marker and Rh factor, but not A marker.
7. AB negative. This blood type has A and B markers, but not Rh factor.
8. AB positive. This blood type has all three types of markers — A, B, and Rh factor.

Having any of these markers (or none of them) doesn't make a person's blood any healthier or stronger. It's just a genetic difference, like having green eyes instead of blue or straight hair instead of curly.

Why Are Blood Types Important?

The immune system is the body's protection against invaders. It can identify antigens as self or nonself. To get a blood transfusion safely, a person's immune system must recognize the donor cells as a match to his or her own cells. If a match isn't recognized, the cells are rejected.

The immune system makes proteins called antibodies that act as protectors if foreign cells enter the body. Depending on which blood type you have, your immune system will make antibodies to react against other blood types.

If a patient gets the wrong blood type, the antibodies immediately set out to destroy the invading cells. This aggressive, whole-body response can give someone a fever, chills, and low blood pressure. It can even cause vital body systems — like breathing or the kidneys — to fail.

Here's an example of how the blood type-antibody process works:

• Let's say you have type A blood. Because your blood contains the A marker, it makes B antibodies.
• If B markers (found in type B or type AB blood) enter your body, your type A immune system gets fired up against them.
• This means that you can only get a transfusion from someone with A or O blood, not from someone with B or AB blood.

In the same way, if you have the B marker, your body makes A antibodies. So as a person with type B blood, you could get a transfusion from someone with B or O blood, but not A or AB.

Things are a little different for people with type AB or type O blood:

• If you have both A and B markers on the surface of your cells (type AB blood), your body does not need to fight the presence of either.
• This means that someone with AB blood can get a transfusion from someone with A, B, AB, or O blood.

But if you have type O blood, your red blood cells have neither A or B markers. So:

• Your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood.
• A person with O blood can only get a transfusion with O blood.
