Suddenly, it came down the drainpipe it was amirical it was … the most amount of lego in the world. Quickly, i ran out-side and started to play with all of the lego first I thought I shouldn’t tell anybody but then I decided I should. I told Jack; Billy and Fred and we all made a massive ship together and it was probably the biggest ship I’ve ever seen made out of lego. Then they all went home and I took most the lego up to my room and I started to make room for the lego ship I made.
Suddenly, it came down the drainpipe and was soaking with water, it was a rat. The drainpipe was filled with rats and mice. It was disgusting to witness and experience however it was kind of scary. The next day I saw another rat as well as yesterday and was red and yellow and blue however there were loads and loads of them there under the pipe. Any way I was going to my friends house and my aunties after I’ve been to my friends house and to have lots of fun. Suddenly I was in a different world. To be continued…
It slowly followed Jade, without her even knowing. The black spirit, slithered behind her, hiding every time she turned around. Jade yawned as she turned on the tap to get some water.
“Oh I am so tired,” moaned Jade. As she went to fill up her glass, the spirit climbed in, not relising it was about to be filled with water.
“Woof,” cried Mimi (Jades dog).
“Mimi!” Jade cried. Tipping the glass forward, the spirit fell up into the tap. Slowly, it came down the drainpipe and into Jades best friends house. There was a shriek from next door… “Was that…GEMMA!”
Our visitor who was called Simon came into our classroom to learn about buoyancy and he has dived in Antarctica and teaches people to dive safely underwater. We learnt about Buoyancy and how it works in water. We were told the less buoyancy you have more heavy the object will be and maybe will sink Or if there is more buoyancy it will float on the surface of the water. However if the weight of the object is the same as the buoyancy the object would float in the water. We made fake divers out of a poppet and white tac and a bottle of water. We filled the bottle up right to the top so if you squeezed the middle of the bottle it would float to the bottom and if you let go it would float to the top. Our class asked questions about his diving experience and what its like to dive underwater for a job. I tried a scuba diving suit on he wore when diving. That was our visitor who came to our school.
Boaty McBoatface is a yellow unmanned submarine, the lead submarine for the research in Antarctica and is owned by NERC (Natural Environment Research Council). The name Boaty McBoatface was suggested by BBC radio presenter James Hand as a joke but the public seemed to like it and it quickly got popular. The vote was originally for naming the ship but as Boaty McBoatface was such a silly name they called the ship RRS Sir David Attenborough and the sub Boaty McBoatface.
Boaty will be carried aboard the vessel RRS Sir David Attenborough (still under construction) as it gets prepared for its dives. Boaty has already been put to work on the RRS James Clark Ross looking at the conditions of the water it is in. It is a new sub and if needed it can operate under ice. It will set sail in 2019 and will hopefully help scientists by checking the levels of krill, ice thickness and will also take measurements of seawater.
On the 30th of January a man called Simon Holebeach came to our class to talk about his experience of being a Polar diver and a instructor, and he also came into to talk about buoyancy: he shown us a slideshow to make it easier to understand. He then went to say if you wanted to sink to the bottom of the river or sea, you need to less buoyancy and if you want to float you need more buoyancy. Then he said if you wanted to stay at the right depth you needed to get the exact buoyancy. After that, he got out his wet suit (which has been all over the world), and he shown us the two holes on the arms that release air and one that sucks in air for buoyancy.
We then went on to make small plastic diver’s, then when we drew faces on the diver’s he put white tack all round the middle of the diver. Then when it was fully stable in water you were able to put it in a bottle, screw the lid on then when you squeeze the bottle it should sink and when you let go it should come to the top again. You now have your own diver
Last week orchid class was visited by… a polar diver. He told us hundreds of facts about what it is like under the water, buoyancy, and what you need to do when you are diving.
Buoyancy can be easy and difficult to learn but you will probably get it in the end. I found it hard to understand at the start but I got it in the end.
How to go down
When you go down there are tow different ways to do it. First, you will have seven weights and if you need more you will go down to the bottom of the sea and pick up a few rocks. Second, you will have air in your suit, so if you need to go down you press a button on the arm of the suit.
How to go up
When you go up there are also tow different ways to do it. First, you will have seven weights like you already know, you just need to take them of until you need to. Second, to go up you can let into the suit but pressing a button, it goes through a vowel and it goes into your suit.
About the divers
Simon Holebeach was the person was the person that came in and told us about everything you and I now know. To be a polar diver you need to pass a few tests to be able to be one. When you are a polar diver you have to help do a few things. First, they need to cut the ice into blocks and take them out using a strong rope. Next, they need to get their dry suit on; you can even where your clothes in it. After that, you can go under water and swim around. Every few minutes you have to tug on the rope to tell the person above water you are fine. Finally, you need to go up from the water really slowly because if you go fast when you get above water your arms and legs would hurt if you move them.
That is all you need to know about buoyancy and polar divers.
The British Natural Environment Research Council, asked the public to help it name a new ship. The most popular name turned out to be Boaty Mc Boat face, but in fact the boat was named after David Attenborough. A little yellow remote control submarine took the name Boaty Mc Boat face. The submarine can travel under ice and reach depths of 6,000 metres. It will transmit the information it collects to researchers via a radio link. It is looking at water flow and water movement in the Southern Oceans.
On Tuesday the 30th of January, a man called Simon Holebeach came to our school to show us all about being a Polar Diver and to tell us some facts about the sea. Simon brought in his diving suit so we could have a look at it and so we could wear it. He wore his suit in lots of different countries like Egypt. He told us his favourite time which was when he was at the bottom of the sea and some seals came over to him and were playing with all of his diving gear.
After that we did a little experiment where you put a pipette in a full bottle of water, the pipette has white tack round it, you put it in the bottle of water and put the lid on, then squeeze it and you pipette should go up and down. Mine didn’t work very well.
Then we got to ask him some questions like “what was you favourite dive you have done,” we also got to try on his diving suit, the people who tried it on looked so funny! I had a really fun time.
Buoyancy is the difference between floating and sinking, or staying in the middle. When you drop a ball full of air into the water it normally floats, that’s because the buoyancy force is stronger than the weight of the ball. If you drop a ball that has no air inside it into the water it will sink. This is because the weight of the ball in stronger than the buoyancy force, so it sinks. If you drop a ball that has a bit of air inside into the water it will float in the middle. This is because the forces are both the same.
A man and a lady came into our school and talked to us about buoyancy, we made little divers out of white tack; a bottle of water and a little tube that water can go inside. If you add lots of white tack it will sink in the bottle of water, that is because it is too buoyant. If you take some off it will make it float. Once it is floating you can squeeze the bottle and the diver will go down. When you let go will go back up, we tried to make it stay in the middle. It was really fun learning about buoyancy and I would like to learn some more.
