T.O.M

3 weeks ago kids from all around the world competed in the tournament of the minds or TOM for short. This is where kids from schools across the world are put in teams and have to do a task based on a certain subject this is the long term challenge. There is also a spontaneous challenge on the day. The subject our team chose was language and literature out of language and literature, applied technology, social sciences and maths and engineering. This year the task for language and literature was to make a picture book that was 12 pages long or less.

We also made a play to go with it too. We thought this was the hardest part to prepare as you have to make all your costumes and props. The basic idea of our book is a king has his crown stolen and someone needs to find it. We also needed to include 2 characters from other books we chose Katniss from The Hunger Games and Pearl Barley from Pearl Barley and Charlie Parsley.

On the day at La Trobe University we were all terrified on how we would do, I was the first person from our team there so I had to pick a spot to put our props and bags I chose by a drinking fountain. Once everyone came we registered and were shown where we  were going to perform. We went into the theater both excited and nervous we performed. After we performed we went to the spontaneous challenge and answered a problem that was open so there were multiple answers. Then it had finished and we went home.

The Science of Bacteria

Bacteria is used as a way of fueling the sewer plant and is used for even more bizarre things! Did you know that bacteria is almost everywhere and is probably on you right now! The only places bacteria doesn’t inhabit are: soil, water, acidic hot springs, radioactive waste and under the earths crust. Bacteria is needed for you to survive by dissolving  compounds into energy. It thrives in deep parts of the world like trenches and even lives inside you. When you poo your poo goes through a sewer pipe and enters a sewer plant  and is processed but the interesting part is that it the poo is transferred and is turned into bio solid which powers the sewer plant. But the bio solid is formed by the bacteria changing the poo so in a way the poo and bacteria powers the plant that processes the poo. Bacteria was even one of the first lifeforms to walk the earth. Bacteria is sometimes beneficial to your body bacteria like Bifidobacterium animalis is good because it aids the digestive system but sometime bacteria can be bad such as Salmonella Typhi this sort of bacteria can kill but not all harmful bacterias kill.

Explanation: The Lifecycle of Stars

This term at MPPS the year 3/4s wrote explantations. They needed to come up with a question and write about it these explantations needed to have features such as: cause and effect, tier 3 words, authors purpose needs to be to teach, and it needs to have a impersonal and serious voice these are some of the features. Heres my explantation on the lifecycle of stars.

Explanation: The lifecycle of stars

Have you ever been gazing up at the stars on a quiet night and asked yourself, “Whether they would stay there forever?” Stars are always above us in space and their life cycle is very different compared to ours. It even uses other stars that explode!

The lifecycle of a star starts with a nebula. A nebula is a cloud of hydrogen, helium and cosmic dust. Nebula is also the Latin word for cloud. When a nebula is affected by an explosion it breaks into smaller swirling clouds. At the centre of these clouds is a protostar. A protostar hasn’t developed its surface properly and doesn’t emit light and heat in the same way. The protostar will get hotter the protostar does this to develop and burn its hydrogen so it can survive and eventually it ignites and a new star is born!

 

The nebula leads to smaller swirling clouds and the protostars and the new star is made

After the star is born it will continue to burn hydrogen for several billions of years the smaller the star the longer it live. As it burns it gets bigger until it gets so big it turns into a red giant. Red giants are enormous and have a huge surface area. They’re mostly made up of gas, and as the name suggests they’re bright red.

When an Explosion affects a red giant the force blows off a layer of its gas which makes nebulas this process continues. Then the red giant turns into a smaller planetary nebula, this is a smaller star enveloped in gas.

  

 Stars burn hydrogen and then turn into red giants that lose gas to become planetary nebulas

Once the planetary nebula loses most of its gas it turns a bright white and is very small and dwarfish. This stage in the life cycle is called a white dwarf the white dwarf will continue to burn its hydrogen until it runs out.

After a star loses all its hydrogen it will explode! Effecting heaps of stars across the solar system. This explosion is called a supernova and it can last several days. It also has multiple types such as the pulsar which consists of several flashes because it has two poles of light with a blue core we see it as it rotates so it’s not actually flashing but your eyes will see this. This is similar to something called the munker white illusion if you type that into your search engine you and click on images you can see an illusion of colours this is similar to what we see as the pulsar rotates.

   

 

Different types of supernovas

Soon after a supernova dies down the star usually dies and is gone. But heavy’s stars shrink until they’re no bigger than a grain of sand instead of dying. But it still has a gravitational pull its gravity is so strong it has the ability to suck in light from a few kilometres away! This is the last stage in the life of a star and this does not happen to all stars it’s called a black hole. Eventually the black holes mass gets so big and it will collapse on itself and die. Then the life cycle continues…

The science of Di Cats (Felis Catus)

Did you know that cat’s spend 85% of there day doing nothing by nothing I mean eating, drinking, pooing, sleeping and generaly being lazy. There nose also has a print just like a human fingerprint. And that catnip is almost like a drug for them because 1 of its natural oils enters the cats system and acts like cat phermone And this will happen in around 80% of cats.  Since cats us scent to communicate when you pat a cat It puts its tail up this means it wants you to smell it’s behind This resembles a hug or hand shake for cats and spread they withe rub against you to put its signature scent on you and otherwise claim you. Some people say cats have night vision this is in fact not true they may have a additional feature in there eye that reflects light out so they can see in dim lights but in complete dark they can see no better then we can. Cats bury there poo not only to not attract predators but to show they are with a dominate cat this’s your cats way of recognising you as dominate. When a cat is angry it will hiss and puff up it’s fur it hiss’s to intimidate other cats and show its teeth. String is a cat toy but it can seriously hurt cats if they catch it between its teeth and eat it this is replaced by laser pointer dots which are very safe as they’re completely harmless and will not blind cats. Cats play because it improves there hunting and fighting skills they may also playfight to reduce there fear of attacking other animals

Diary of a INsANe Bunny/Rabbit

Day 1:

CarrOTS BGHFVYUJHG MUSt get CARRots ARRGGG EAt all CRarrots! Carrot GHFTGHF ArrGGGGG 5 hours earlier…

It was morning at the break of dawn and my minions have showered me in carrots like usual I ate all of them but one carrot seemed out of place It was glowing green against the pure white light emitted by my presence as king of everything. It was talking to me it said “Eat me Eat me EAT me!” It’s voice was hypnotic I ate the carrot then I went to bed and slept. I woke up and I went CRAzy “CarrOTS BGHFVYUJHG MUSt get CARRots ARRGGG EAt all CArrots! Carrot GHFTGHF ArrGGGGG EAT EAT uywhgeduwjgd YARRggG AGGGA CARROts CUYFG ARR” I yelled wildly. Then suddenly plop! and I fell backwards into the …

Swimming sports

The school wa sdoing swimming sports at queens park pool today. It was time for the relay the microphone roared loudly as we as we all walked to the diving boards and I went behind the yellow cone because I’m in the chisholm house. I felt both nervous and exicited. The four of us talked while the others where swimming “I can’t wait I wailed as I watched the others swim.

Suddenly our conversation ended as the teacher told us to swim in to our lanes this is when I feel like I need to go to the toliet and I’m drouned in clorine and I’m overloaded with energy! We jumpped into our lanes with all the other competiters I noticed the water was warm I whispered to my teammate “I wonder if someone weed in the water.” “I hope not.” She replied. Then the starter gun went off and my teammate started swimming they got to the other end then my other teammate swam lastly it was my turn to swim I came second.

At the end of the day they anounced the results and over all our team (Chisholm) came first! 🙂

Professor Bunsen Incursion (recount)

Today the year 3/4s had an incursion at school, Professor Bunsen came to our school to teach us children about science as that is our topic this term. He did so many experiments I’m sorry if I don’t list them all. First he showed us a special flower he called gun-cotten (was sure it’s just cotten that hasn’t been tampered with) he grabbed a electric fire lighter held it againest the flower and Boom! The cotten burst into flames, the science behind this was that before havested the cotten like other plants absorb energy from the sun this energy makes it easier to explode/burn. This is like how in a car crash the energy made by petrol just before the cars collide is the energy that breaks/damages the car.

 

Gun cotten burning

 

He also stuck 2 bottles together 1 filled with air and the other filled with water. He tipped the bottles upside down and The water didn’t flow down it stayed up because the air had nowhere to go and it stayed in the bottle. Then he shook the bottle and a mini tornado appeared and drained all the water into the other bottle and the air swapped bottles too.

He also told us how to change the colour of liquids. If you have red cabbage juice and you put it into a cup with a base such as soap, and It wiull go darker and pour that into a cup with citric acid such as the juice from oranges It will go lighter because red cabbage juice is a base and acid indicater.

We also put water, aluminum foil and drain cleaner into a wine bottle and sealed it with a balloon. After a while we all noticed the balloon was getting bigger and bigger. Eventually The balloon was huge! The aluminum foil was gone and a black liquid was left in the bottle also the bottle was so hot if you touched it it would rip the skin off you hand.

Lastly we put water in a bottle so mit was half full put it on a bicicle pump and it flew off into the sky and beyond!
