The dinosaur roars,
Snatching its unlucky prey.
It feasts on the meat.

 The snow falls to Earth.
The flakes sprinkle like paper,
Calmly from the clouds.

My Friend is a Bouncing Basketball

My friend is a bouncing basketball.
Sometimes up and sometimes down.
He is always on the court,
No matter what comes in his way.
He has the grip of a fresh new ball,
That you can’t let go of.
He spreads joy across the court,
With a few laughs along the way.
He never leaves,
And we both go for the basket as a team.

The Skipping Rock

            The rock skips on the water surface,
Sometimes up and sometimes down.
Hopping ever so quickly.
Flying in the air,
Thudding against the water.
Tasting freedom in the sky,
Yet slowing down every drop.
Getting wetter every moment,
Until it plunges deep into the sea.
Orko Oyon 7B

You Are Like….

You are like a water fountain,
Sprinkling joy everywhere.
You are like the shining sun,
As bright as can be.
You are like a gummy bear,
Always soft and always sweet.
You are like the start of a book,
Making me want to read more and more.
You are like a sparkling diamond,
                              Rock hard and precious.

The Killer Whale (Orcinus Orca)

লিখেছেন Orko Oyon   
Saturday, 04 February 2012
The killer whale has black and white body. It has a white eye patch just above its eye. The bottom of its body is white and the top is black. It has two black pectoral fins under on the sides of its belly, a black dorsal fin on the top of its body and a fluke at the opposite end of its head on its body. The killer whale has a sleek oval body shape.
          The killer whale has a variety of adaptations that allow it to succeed in its oceanic environment. The killer whale lives in an ecosystem with the ocean surrounding their environment so they would need a lot of adaptations to help them live that type of ecosystem.
          There are a lot of physical adaptations of the killer whale to help it succeed in its ecosystem. One obstacle of having the ocean as the Orca's home is that it would be very cold living there. The killer whale has many adaptations to help conserve its body heat. Like most mammals, killer whales have a thick layer of fat called blubber  which helps the killer whale keep its warmth on the inside of its body. Also, they have a high metabolic rate keep its warmth. The arteries in the killer whales body are surrounded by veins. The arteries contain the heated blood that goes closer to the core of the body and the veins contain the cooled blood that is closer to the outside of the body. The heat from the arteries is transferred into the veins so that the heated blood can go to the inside and the outside of the killer whales body. Here is a diagram that also explains this heat transfer:

          Heat isn't just the only adaptation that the killer whale needs to succeed in its aquatic environment. They also need some physical adaptations for swimming in the water. For a start, they need adaptations to help them paddle their way through the water. That is where their pectoral fins come in to action. The pectoral fins are two fins that are under the sides of the killer whales body and they help the killer whale steer and accelerate through the water. If you were to take an x-ray of the pectoral fin, the bones in it would look similar to bones of a human's hand.

          The dorsal fin can grow up to six feet and the one that is on the top of the killer whales body. It is used for stability while it is swimming. The flukes are the two flippers at the end of its body. They are used for slowing down and stopping.  The image below shows the body parts that would be on a killer whale (the English translations are in italics)
          The killer whale is a very good swimmer and a diver. They can swim up to 45 kilometers per hour, but only for a few seconds. They usually cruise at around 13 kilometres per hour which they can do for long periods of time. The killer whale can dive about 100 meters deep. Although the longest recorded dive by a killer whale was 274.3 meters which was under experimental purposes. They can dive for as long as from 5 to 15 minutes and they slow there heart rate when they dive; so less blood is needed to help the muscles function with very little oxygen.
          The killer whale needs to learn how to conserve oxygen because they cannot breathe under water. They only breathe at the surface of the water through their single blowhole at the top of their head. They exhale right before they reach the surface of the ocean and quickly inhale oxygen when 0their blowhole is above the surface of the ocean and exposed to air. Killer whales can open and close their blowholes using a muscular flap. When the blowhole is closed, it is in a relaxed position. To open their blowhole, they open the muscular flap and breathe in oxygen.
          Killer whales figure out ways for conserving useful energy underwater.
They are amazingly agile when it comes to swimming. Their body shape is shaped to help them swim quicker through the water (aerodynamic). They also ride the ocean waves to save more energy of paddling with their pectoral fins. The calves of the pod swim close enough to their mother so they can get the "slipstream" of their mother to help them swim faster and by doing less work.
          To help killer whales hunt, they use something called echolocation to locate their prey. Echolocation is where they send some high-frequency pulses or click through the ocean so it can the echo can bounce off of their prey and return the echo to the killer whale so that they know that something is up ahead. The killer whale sends these sounds from the "melon" and they get the echo back in the auditory "bulla".
          Physical adaptations are not the only adaptations the Orca has. It also has some special behavioural adaptations, too,
          Killer whales stay in pods. They use large pods for hunting schools of fish and large animals (sperm whale, blue whale etc.) and they use smaller pods to attack and kill marine mammals like seals. The Orca whales stay in pods so they can protect their young from getting injured or even killed, even though there are not very many predators in the ocean to the killer whale (besides humans) since they are the most feared animal in the ocean.
          Killer whales are able to slow their heart rates when they are diving. This helps the whale need less oxygen to go to the muscles of the body so that their muscles can work better with less oxygen.
          Pods of killer whales have their own call. This helps to call their friends and family when they are in danger or they found a prey but one killer whale can't kill it alone.
          Killer whales have very complex relationships with other marine animals. They have been caught harassing but not eating the marine mammals. In a video I have watched, the killer whales have been caught getting a seal on shore and playing with it by launching the seal up in the air with their mouths and their fluke at astonishing heights. You can watch this video here:
          Killer whales have been known to interact with humans. They have been known to "show off" for them. They can be taught to do tricks that humans had taught them to do and perform in shows for an audience with food as a reward.
           Not very many people know where the killer whale migrates, but some studies show that killer whales seem to migrate where their prey migrates so they can have food during the winter.
Reasons for Being Endangered
Killer whales have many reasons for being endangered and almost all of them revolve around one of the only threats to the killer whale: humans.
Killer whales have lost most of their habitats due to pollution and loss of food source. Humans have been polluting the oceans with garbage, oils spills and more and the killer whales cannot live in those deadly waters.
There is also a reduction of food source in some areas which causes killer whales to die since they do not have a food source or because they might have relocated and died along the journey by being tired, caught in fishing nets and in other situations. The problem also might be that the killer whales might eat too much that the food in the area decreases, which in result kills them.
Another problem that is now illegal but still affected the population of the killer whale is whaling. Whaling is where humans go out into the waters to kill whales for sport and for blubber and so they can consume their meat.
Salmon may be the killer whales main food source, but the problem is that the population of salmon is decreasing which isn't very good for the killer whale.
Traumatic events to the killer whales caused by humans can also bring the population of the Orca whales down. An example of a traumatic event is that 400 Orca whales experienced and oil spill in the 1990's. The scientists recorded that there are only 7 whales left and there has been no sign of reproduction since then.
Another big situation is that the killer whales are being held in captivity. They are used for shows and are used to be displayed at zoos. But research show that killer whales die quicker in captivity than in the wild.
                Humans are pretty much the ONLY thing that has impacted this species. The humans used to "whale" for fun which means they got to kill whales through boats. Luckily, this became illegal in 1986. But now there is a new problem: pollution. The humans pollute the water which causes the Orca's to die or have troubles to reproduce. Another situation is that the killer whale's food source population is decreasing because of fisherman or because of the killer whale eating too much of their food source which makes the population decrease. So that when they have to move somewhere to get there food source again, they could die along the way or they might get caught in fishing nets and get killed by boats.
Scientists have no idea of where the killer whales go or stay. This means that we do not know where to protect the killer whale's habitats. Scientists are trying to figure out where the killer whales homes are so that they know where to protect the killer whales.
The killer whales have very interesting habitats and a pretty demanding ecosystem.
The killer whales usually live near coastal waters because they like colder temperatures in their water. Some killer whales even like living near Antarctica! But some prefer to live in warm waters like Hawaii, Australia and the Galapagos Islands.
Killer whales are the most widely distributed mammal besides humans and the live in all of the oceans and some of the seas.
The killer whale needs a lot of biotic things in its ecosystem. A killer whale definitely needs this because the only thing it eats is meat (carnivore/consumer). Things the killer whale eats are fish, sharks, squids, marine mammals (whales, seals), turtles, octopi, birds, octopi, minke whales and penguins. So of course all of these things would need to be in its ecosystem and more since the animals that the killer whale eats need to eat as well and so on.
There are also a few abiotic factors the killer whale needs in its ecosystem. The biggest thing that the killer whale needs surrounds them their whole life time: water. Without the water the killer whale would have no use of their fins and they wouldn't be able to walk around because they do not have any adaptations to get around on land. Killer whales also need oxygen because without it they would either suffocate or drown. Orca whales also like cold temperatures and coastal areas which also count as an abiotic factor, too.
The killer whale depends on many things in its ecosystem to survive, biotic and abiotic.
It depends on biotic things in its environment like fish, sharks, squids, marine mammals (whales, seals), turtles, octopi, birds, octopi, minke whales and penguins to be in their environment so they can have a food source in their environment. They also need to depend on the food source of their food source so that their food source wouldn't move locations or die.
The killer whale depends on abiotic things like oxygen and air. The reason it needs oxygen is because any living thing needs to breathe, including a killer whale. The killer whale would asphyxiate without any air. It also needs water because it can only move in water which can help a lot in hunting. If the killer whale lived on land, animals could easily hunt it down because the killer whale would stay in one spot.
          The killer whale would definitely be able to survive in a jungle ecosystem for very long. There are many things wrong with a land ecosystem itself for a killer whale.
          First of all, the killer whale would not be able to survive on land because it needs water to move. It has adaptations like its fins that are meant to be under water so it can be able to swim. On land, the killer whale won't be able to move because it has no land adaptations like legs or arms. This way the killer whale would make an easy target for carnivores because the killer whale wouldn't be able to make a quick getaway or fight back.
          The killer whale would have a very big struggle with getting food because it wouldn't be able to move to catch its prey. This way, the killer whale would have a shorter life span.

Saving the Killer Whale
There is a variety of things the humans can do to save the killer whale. We could figure out where the killer whale lives so that we know where their habitat is and we know where to protect.  We could do our best to stop polluting the oceans so that the killer whale doesn't die from oil spills and more. We should be careful with our boats and fishing gear because they have killer a variety of killer whales.
What has been done and is being done is that by law, whaling is now illegal since 1986. The government hasn't given out any whaling licenses since then.

When we were younger kids, we all thought that this day would take a long time to arrive. But with years of hard work and dedication, we are finally rewarded.
We could not have done it without all of our teachers like Mrs. Godfroid and Mr. Forman. All of us thank you for helping us and teaching us. Every single teacher here at our school helped us learn and grow as people. I’d also like to thank everyone’s families for supporting and helping us when it came to our education. Mr. Thompson, our principal deserves a thank you as well for making this school such a great place to learn. Lastly, I’d like to thank my classmates. They encouraged each other whether it was indoors or outdoors. They are always friendly and kind to each other and have worked very hard. We could not have gotten this far without our friends.
     Of course with all of those people, we had memories. A week ago, we went camping. All of us enjoyed singing “The Wheels on the Bus” and to watch people in a skit faint from chocolate pudding. At Southwood, we all enjoyed competing and winning ribbons. Most of them were fourth place but we still had fun. The choir had presented an amazing performance at the anniversary of our school along with the students performing skits. The We Day group raised over a thousand dollars from a dance, movie day and garage sale that the whole school enjoyed. Last but not least is Grade 6 Testing. We all absolutely loved getting three booklets of work flopped down on our desks with only three days to finish. I bet everybody just admired getting dizzy from all those words.
     Either way, all that work has brought us to this day. Some of us might be going our separate ways but we all are going to be connected through this school.
     I’d like to wish Avenue Road a happy 50th birthday, our teachers to help kids learn, Mr. Thompson to continue to lead a great school, Mr. Pearce and Mrs. Cameron a happy retirement, Mr. Wilson to keeping this school shining and finally, my classmate to a great year in Grade 7.

In these series of articles, I will talk about some of my favorite Greek heroes who have saved their country from people and monsters who threatened mankind. Explore more.... 
Achilles was great hero. He was a part of the Trojan war, a battle that went on for 11 years. He was unstoppable. The reason he was unstoppable was because his mother, Thetis, dipped him in the River Styx in the Underworld, holding him by the heel so that when someone hit him, it wouldn't do any harm to him.
In the war, he helped his country a lot. Another warrior was mad at him, though. Because he had killed his brother, Paris had finally ended the life of this unstoppable hero.
The god Apollo had helped Paris to shoot an arrow into Achilles' tendon, which is another word for the heel. His heel was the only thing that wasn't dipped into the river. It was the one his mother held him by. Of course even Achilles couldn't resist that. So he slowly fell to his death. But today almost everyone remembers Achilles. We remember when we hear and say our own body part, the Achilles' tendon.

In these series of articles, I have written some parts of space history. But it is kind of hard to picture a moment of history with only words. So I have added a picture to every single "Space History" article.
I hope you enjoy all of the articles I have written.  Explore more.... 
Edwin "Buzz" Aldrin, Jr., the pilot of the Lunar Module is seconds away to walk on the moon. You can see our earth in the background. The picture was taken by astronaut Neil Armstrong.

                 Neptune is the farthest planet from the sun. It was named after the Roman God of the sea. The Greek’s call Him Poseidon. Neptune’s size in diameter is 49 530 kilometres. It is the fourth largest in mass. A year in Neptune would be 165 Earth years. A day in Neptune would be 16 hours. In its thick atmosphere, there is 74% hydrogen, 25% helium and 1% methane. Neptune has the fastest winds in our Solar System. The Great Dark Spot on Neptune is similar to the Great Red Spot on Jupiter. The Great Dark Spot may disappear and reappear again. This massive storm would go counter clockwise. It is so fast that it goes at least 2 100 kilometres per hour.
                Neptune is the third largest planet in mass. It is 17 times the mass as Earth. It is a little bit bigger than its neighbour, Uranus.
                Neptune was discovered on September 23rd, 1846. Neptune has been visited once by the Voyager 2 which flew by Neptune on August 25th 1989. It had taken pictures of Neptune and sent it back to Earth. The fact that this blue planet is an outer planet, it is a gaseous planet. It has 13 known moons.
                Neptune has active and visible weather patterns. Because of Neptune’s distance from the sun, its outer atmosphere is the coldest destination in our Solar System. In the clouds, it could reach up to maybe -218°C. At the centre of this planet, it would be at least 5 000°C, though.
