Aaah, Help Me!! | Chemicals and Chaos

Welcome to another post on my blog. In today's post, I am sharing my task that I completed in Chemicals and Chaos. In Chaos, we had done an activity about the Zombie Apocalypse. The teacher explained the instructions and then did the work independently. There were 34 rules to survive in a Zombie Apocalypse and we had to either make it in Canva, Google Drawing or Piktochart. I chose to do the task on Google Drawings, here is my work. I hope you like it.

Filtration | Chemicals and Chaos

Welcome to another post on my blog. Today in Hur 3, Chemicals and Chaos, while doing Chemistry, we are doing an experiment about filtration, this experiment will include chemicals being separated.


Aim: To Separate a solution from a precipitate.

Hypothesis: I think that both will separate

Equipment:

  1. Sodium sulfate
  2. Conical flask
  3. Stirring rod
  4. 200ml Beaker
  5. Funnel
  6. Filter paper

Method:


1. Pour approximately 50mL of copper sulfate solution into a beaker.
2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form. Called copper carbonate. 
3. Watch demo then fold filter paper to fit inside the funnel
4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask. 
5. Stir the mixture in the beaker, then carefully pour it into the funnel. 
6. Observe what happened.

Observation:

When we mixed Copper Sulfate and Sodium Carbonate, the 'carbonate' and 'sulfate' swapped and turned to;

Copper sulfate + Sodium Carbonate turned to Copper carbonate + Sodium sulfate 

The Copper carbonate stayed on the filter paper and the sodium sulfate filtered down.

Rats (Kiore) | Chemicals and Chaos

Welcome to another post on my blog. In today's post, I am sharing the work that I had done in Chemicals and Chaos, it was about Rats/Mice.

Rats/Mice can cause so much chaos!


Questions for Mice Video (Plague)

  1. Where did this happen?
    • Western Australia
  2. How did this happen?
    • The weather was rainy and sunny and rats came and ate all the crop food and spread all around.
  3. How much offspring (Babies) can 2 mice parents make?
    • 2000
  4. How much wheat did the mice eat?
    • 5000
  5. How did they get rid of the mice and how many dead mice were there?
    • Poison - 1080. 100 million rats were dead.

Sometimes Rats/Mice are not seen as chaotic


Questions for Rat Temple video

  1. Where is this happening
    • Northern India
  2. Why is this happening?
    • They consider rats as gods, they worship them and they believe in the reincarnation.
  3. What special treatment do the rats get?
    • VIP treatment, they were served as celebrities, you can eat with them, they taste the food anytime. Rats in the kitchen meant good luck for them.

Welcome to another post on my blog. Today, in Health, we had to debate about, 'Online relationships are not as important as real-life relationships'. We had to write our debate on our blog.


Some people may think that online relationships are as important than real-life relationships, this may be because they can interact with people any time and anywhere, which incorporates online video chat and online fun. Another point of view is dangers if you are in a relationship with someone you don't know it can be dangerous. It is more dangerous if you don't know how they look, what they do, etc.

But on the other hand, some people believe that real-life relationships are more than online relationships, this may be because you can't have fun going to places together than having fun online. Among real-life relationships, you can go to places, eat together and do other things together in real. You can go to the ice-cream store and have fun talking beside each other.


In conclusion, I think that 'online relationships are not as important as real-life relationships' because it may not be safe and there is a different feeling to be present with them rather online.

The Present

The Present - OFFICIAL
Credit: https://thevideosuite.com/the-present-official/
Welcome to another post on my blog. In today's post, I am sharing the activity that I've finished in Wānanga yesterday. As a class, we watched the video, 'The Present'. The video informs us that we need to be resilient and create connections. The body acknowledges that the dog is not kept back by his missing paw. The dog is playful, resilient and happy.




We were given a few questions to answer after watching the video, such as;


How would you describe the boy at the start of the video?


  • Angry
  • Gamer



What did he think of his present?


  • Happy at the start
  • Angry after seeing that the dog doesn't have a paw


Why didn't he like him?


  • Because of his paw


Why do you think he didn't want to play with him?


  • He was interested in his game


Why did the mum choose this dog for her son?


  • Because he doesn't have a leg, so she picked a dog which doesn't have a paw.



How do you think the boy feels about himself?


  • Bad because he is not the only one without a leg.



What message do you think the story is trying to teach us?


  • To be happy what you're given
  • Never give up - Dog



After that, we had to write a diary from the boy. I hope you like it.




One really hot afternoon I decided to play Xbox 360 when my Mum was at work. I closed the blinds because it was too hot. I had a selection of games on the TV cupboard.

When Mum arrived from work she had a box in her hand. Then Mum put the box in front of me.

“What was inside the box? Was it a new console, a comic? or something else?” I thought.

I was still playing on my Xbox 360, then my Mum had a phone call. My Mum said before answering the phone call “I’ve got a present for you. Open it.” I decided to open the box to see what is inside it?

When I opened the lid of the box a dog barked at me. It had bright yellow skin with a black nose and brown eyes.

I called out “Wow!! Awesome!!” The best present ever!!”

When I picked up the dog I saw that he had a half left leg. I dropped the dog on the ground.

The dog sat up and came to me, I kicked the dog and said: “Get lost!”

When the dog was looking upside down he saw a red softy ball under the table. The dog ran and smacked the cupboard door on his head (crash)! After getting the ball he ran to me with the red ball. I kicked the ball and hit the box that the dog came in and still carried on with my game. The dog ran but fell down on the ground because of his left arm the dog sat up and ran but fell again. He jumped and trapped himself in the box. He tried to find the ball but he couldn’t find the ball instead he smacked the TV cupboard. After getting out of the box the dog couldn’t find the red ball in the box. I laughed. Then I remembered that I had to concentrate on the game. I couldn’t concentrate because the dog was barking and running to get the red ball. When the dog noticed me watching him the dog ran the ball to me with the red ball in his mouth. But fell down, after falling down the dog tried to balance himself to not fall down. The dog dropped the ball in front of me.

“Maybe it’s awesome with a friend that has got half a leg like me?” I thought.

I took the ball, got the crutches and put the ball in my pocket.

“Mum we’ll be outside,” I said to my mum.

We played fetch out in the front yard the whole afternoon.


I hope you like my post about 'The Present'. Have a nice day!! Bye!!!

The Extinct Moa

Welcome to another post on my blog. In today's post, I am sharing information about the extinct moa that was a flightless bird in New Zealand. 



Photo by Sciencemag.org
Moa is New Zealand’s largest birds apparently became wiped out within one hundred of humans first landing in New Zealand, about 1300 AD. Although, there were unconfirmed sightings of moa by whalers and sealers into the 18th and even 19th centuries. Moa is ostrich-like flightless birds native to New Zealand and compose the order Dinornithiformes. Approximately 600 years ago, moas abruptly went defunct. Their extinction coincided with the appearance of the first humans on the islands in the late 13th century, and scientists have questioned what role hunting by Homo sapiens (Humans) played in the moas’ deterioration.

Scientists have long debated about what began the extinction of many species of giant animals including mammoths, mastodons, and moas, occurring between 9000 and 13,000 years ago when humans started to spread around the world. Usually, the animals abandoned shortly after humans landed in their habitats, directing some researchers to recommend that we killed them by overhunting. But some scientists have led to natural conditions, such as disease, volcanic eruptions, and climate change at the end of last Ice Age, as the key causes for these species’ dies. The moas show an especially fascinating case, researchers say, because they were the last of the giant species to disappear, and they did so recently when a changing environment was no longer a factor. But did other natural reasons set them on a direction to unconsciousness, as some scientists suggested in a 2004 paper?


Moa were nine species. The two largest species, Dinornis robustus and Dinornis novaezelandiae reached around 3.6 metres in height with neck outstretched and weighed around 230 kilograms. They were the only wingless bird identified to have existed, yet their cousin the flightless kiwi still has small underlying wings covered under its feathers.

According to Maori tradition, moas were speedy runners that protected themselves by kicking when cornered. Early Polynesian peoples captured moas for food and made spear points, hooks, and ornaments from their bones and water transporters from their eggs.


Moas were mainly browsers and grazers. Inference from skeletal and other remains unveils that they ate seeds, fruits, leaves, and grasses, which were ground with the help of more than 3 kg of stones in the gizzard. Moas laid one large egg, up to 18 cm in diameter and 25 cm long, in a hollow in the ground.

Who Invented the Light Bulb?

“Everything, anything is possible; the world is a vast storehouse of undiscovered energy.”
 - Thomas Edison  

Thomas Edison says electricity will cure everything (1914) - Click ...
Thomas Edison (1914)
"Electricity will cure everything"
Thomas Edison is acknowledged with inventions such as the first light bulb and the phonograph. He used over 1,000 patents for his inventions.

Encyclopædia Britannica, Inc.

Thomas Edison (Thomas Alva Edison), was born on 11 February 1847, Milan, Ohio, United States, is an American inventor who held a world 1,093 patents. He also created the world's first industrial research laboratory. He was the youngest of seven children of Samuel and Nancy Edison. His father was an exiled political activist from Canada, whilst his mother was ana accomplished school teacher and a major influence in Thomas Edison's early life.


Early Age

At an early age, he began hearing problems, which have been inconsistently attributed but were most expected caused by a familial tendency to mastoiditis (is a bacterial infection of the mastoid air cells surrounding the inner and middle ear.). Whatever the reason, Thomas Edison's deafness strongly influenced his behaviour and career, implementing the urge for several of his inventions.

In 1854, Samuel Edison became the lighthouse keeper and carpenter on the Fort Gratiot military post near Port Huron, Michigan, where the family lived in a substantial house. He attended public school for 12 weeks. He was a hyper and wild child, prone to distraction, he was considered "difficult" by his teacher.

His mother quickly got him from school and taught him at home. At the age of 11, he gave a voracious thirst for education and reading books on a broad variety of subjects. In this wide-open curriculum, Thomas formed a method for self-education and learning individually that would help him during his life.

Thomas Edison’s shortage of regular schooling was not surprising. At the time of the Civil War, the average American had attended school a total of 434 days, little more than two years of schooling by today’s standards.

In 1859, he quit school and began working as a train boy on the railroad between Detroit and Port Huron. Four years before, the Michigan Central had initiated the commercial application of the telegraph by using it to control the movement of its trains and the Civil War brought a vast expansion of transportation and communication. Edison took benefit of the opportunity to study telegraphy and in 1963, he became an apprentice telegrapher.

Edison moved to New York City, where he initially went to a partnership with Frank L. Pope, a noted electrical expert, to produce the Edison Universal Stock Printer and other printing telegraphs. From 1870 to 1875, Thomas Edison worked out of Newark, New Jersy, where be made telegraph-related products for both Western Union Telegraph Company and its rivals.

Edison's mother died in 1891, and that same year, he married 16-year-old Mary Stillwell. To overcome his costs and the attraction to spend money, Edison brought his now-widowed father from Port Huron to build a 2 ½-story laboratory and machine shop in the rural environs of Menlo Park, New Jersey, 19 kilometres south of Newark, where he moved in March 1876. With him were two key partners, Charles Batchelor and John Kruesi. Batchelor, born in Manchester in 1845, was a master mechanic and draftsman who integrate Edison perfectly and served as his “ears” on such projects as the phonograph and telephone. He was also in charge of fashioning the drawing that Kruesi, a Swiss-born machinist, translated into models.


Edison encountered his finest hours at Menlo Park. While experimenting on an underwater cable for the automatic telegraph, he observed that the electrical resistance and conductivity of carbon (then called plumbago) changed according to the weight it was beneath. This was a significant theoretical discovery, which allowed Thomas to devise a "pressure relay" using carbon rather than the usual magnets to vary and balance electric currents.

In February 1877, Thomas Edison began experiments made to provide a pressure relay that would expand and develop the audibility of the telephone, a machine that Edison and others had examined but which Alexander Graham Bell was the first to patent, in 1876. By the end of 1877, Thomas had produced the carbon-button transmitter that was applied in telephone speakers and microphones for a century thereafter.



The Phonograph

Thomas Alva Edison invented numerous items, which includes the carbon transmitter, in reply to specific demands for new products or improvements. But he also had the gift of serendipity: when some unexpected appearance was witnessed, he did not wait to finish work in progress and set off track in a new path. This was how, in 1877, he attained his most original discovery, the phonograph. Because the telephone was thought a modification of acoustic telegraphy, Edison while the summer of 1877 was trying to devise for it, as he had for the automatic telegraph, a device that would copy signals as they were received, in this instance in the form of the human voice, so that they could then be delivered as telegraph messages. (The telephone was not yet conceived as a general, person-to-person means of communication.) Some earlier researchers, prominently the French inventor Léon Scott, had theorised that each sound if it could be graphically recorded, would create a distinct shape resembling shorthand, or phonography (“sound writing”), as it was then known. Thomas Edison believed to reify this theory by applying a stylus-tipped carbon transmitter to make marks on a strip of paraffined paper. To his amazement, the barely visible imprints formed a vague imitation of sound when the paper was drawn back under the stylus.

In December 1877, he revealed the tinfoil phonograph, which replaced the strip of paper with a cylinder wrapped in tinfoil. It was greeted with wonder. Certainly, a leading French scientist declared it to be the trick device of a genius ventriloquist. The public’s amazement was soon followed by universal recognition. Edison was projected into worldwide prominence and was entitled the Wizard of Menlo Park, although a decade spent before the phonograph was changed from a laboratory curiosity into a commercial product.


The Electric Light

While Edison was not the inventor of the first light bulb, he got the technology that helped bring it to the masses. Edison was driven to perfect a commercially practical, efficient incandescent light bulb following English inventor Humphry Davy’s invention of the first early electric arc lamp in the early 1800s.

Over the decades following Davy’s creation, scientists such as Warren de la Rue, Joseph Wilson Swan, Henry Woodward and Mathew Evans had worked to perfect electric light bulbs or tubes using a vacuum but were failed in their attempts.

After purchasing Woodward and Evans' patent and making adjustments in his design, Edison was allowed a patent for his own upgraded light bulb in 1879. He began to produce and market it for public use. In January 1880, Edison began to contract a company that would produce the electricity to power and light the cities of the world.

That same year, Edison established the Edison Illuminating Company, the first investor-owned electric utility, which later converted to General Electric.

In 1881, he left Menlo Park to start facilities in several cities where electrical systems were being installed. In 1882, the Pearl Street generating station gave 110 volts of electrical power to 59 customers in lower Manhattan.

Frequently, the Menlo Park property was used simply as a summer home. In August 1884, Thomas Edison’s wife, Mary, experiencing from deteriorating health and subject to periods of mental derangement, died there of “congestion of the brain,” apparently a tumour or hemorrhage. Her death and the move from Menlo Park about the point the midway point of Thomas' life.

He built a large property and research laboratory in West Orange, New Jersey, with facilities containing a machine shop, a library and buildings for metallurgy, chemistry and woodworking. Spurred on by others’ work on developing the phonograph, he began working to make a commercial model. He also had the plan of combining the phonograph to a zoetrope, a machine that strung together a group of photographs in such a way that the images appeared to be moving. Working with William K.L. Dickson, Edison accomplished in creating a working motion picture camera, the Kinetograph, and a viewing instrument, the Kinetoscope, which he patented in 1891.

Synchronising sound and motion showed of such an overwhelming problem, but, that the idea of linking the two was rejected, and the silent movie was born. Edison produced at the laboratory the world’s first motion-picture stage, nicknamed the “Black Maria,” in 1893, and the following year Kinetoscopes, which included peepholes that provided one person at a time to view the moving pictures, were launched with excellent success. Competing inventors soon developed screen-projection systems that hurt the Kinetoscope’s business, however, so Edison acquired a projector developed by Thomas Armat and introduced it as “Edison’s latest marvel, the Vitascope.”

Another derivative of the phonograph was the alkaline storage battery, which Thomas started making as a power source for the phonograph at a point when most homes still required electricity. Despite it was 20 years since all the problems with the battery were resolved, by 1909 Edison was a leading supplier of batteries for submarines and electric vehicles and had even made a company for the manufacture of electric automobiles. In 1912 Henry Ford, one of Edison’s biggest followers appealed him to invent a battery for the self-starter, to be introduced on the Model T. Ford’s request led to ongoing contact within these two Americans, and in October 1929 he organised a 50th-anniversary celebration of the incandescent light that turned into a universal glorification for Thomas Edison.

Most of Edison’s successes involved electricity or communication, but throughout the late 1880s and early 1890s, the Edison Laboratory’s top priority was the magnetic ore-separator. Edison had first worked on the separator when he was searching for platinum for use in the experimental incandescent lamp. The project was assumed to separate platinum from iron-bearing sand. Throughout the 1880s, iron ore prices rose to unparalleled heights so that it appeared that, if the separator could extract the iron from unusable low-grade ores, then forgotten mines might successfully be placed back in production. Edison bought or received rights to 145 old mines in the east and established a large pilot plant at the Ogden mine, near Ogdensburg, New Jersey. He was never capable to overcome the engineering difficulties or work the bugs out of the system, but, and when ore prices fell in the mid-1890s he gave up on the plan. By then he had liquidated all but a small part of his holdings in the General Electric Company, sometimes at very low prices, and had grown further and further apart from the electric lighting field.


Later Life of Edison

Failure could not dishearten Edison’s passion and enthusiasm for invention, however. Despite none of his later designs was as successful as his earlier ones, he proceeded to work even in his 80s. His growth from a poor, uneducated railroad worker to one of the most famous men in the world made him a national hero. More than any other person, he was recognised with building the structure for modern technology and society in the age of electricity.

Edison’s career, the achievement of the American dream of rags-to-riches constant hard work and intelligence, made him a folk star to his citizens. In character, he was an uninhibited egotist, at once a tyrant to his workers and their most entertaining companion, so that there was never a monotonous time with him. He was appealing and attracted publicity, but he had difficulty socialising and disregarded his family. His shafts at the expense of the “long-haired” fraternity of scientists sometimes led formally taught scientists to deprecate him as anti-intellectual; yet he used as his aides, at many times, a number of famous mathematical physicists, such as Nikola Tesla and A.E. Kennelly. The different nature of his forceful personality, as well as such irregularities as his ability to catnap anywhere, contributed to his legendary status. By the time he was in his middle 30s, Edison was announced to be the best-known American in the world. When he died (18 October 1931, West Orange, New Jersey) he was adored and mourned as the man who, more than any other, had placed the foundation for the technological and social cycle of the modern electric world.

The 2002-2004 SARS outbreak was an epidemic involving severe acute respiratory syndrome (SARS) caused by severe acute respiratory syndrome coronavirus (SARS-CoV or SARS-CoV-1). The outbreak was first identified in Foshan, Guangdong, China, on November 16, 2002.

There were over 8,000 people from 29 countries and territories were infected and 774 died worldwide. The significant part of the outbreak lasted for 8 months since the World Health Organization declared SARS held on 5 July 2003. But, several SARS cases were reported until May 2004.

The ongoing COVID-19 pandemic is caused by SARS-CoV-2, a strain of coronavirus related to the one which causes SARS.


Symptoms of SARS CoV involve fever, cough, severe headache, dizziness and other flu-like illnesses. The illness presents as atypical pneumonia that seems not to react to regular treatments. There were 8,098 confirmed cases of SARS from November 2002 to July 2003, with 774 deaths.

Overview

In November 2002, doctors in the Guandong province of southeastern China started to see the first cases of what would become recognised as SARS or 'severe acute respiratory syndrome'.
