Speech 2017 (Bad things that have a good result)

Have you had a bad thing turn into a good result, like you're dreading to go to somewhere but turns out ok, or you're fearing the worst and ends up in a good result?… well I've got a few examples of it i'd like to share.      

For my 11th birthday can you believe it I got a 10 year old card from my nana. I was really embarrassed and told mum. Then mum said well we can ring her later, and tell her that you are actually 11, but then mum added at least you only got one wrong card, and then even worse my nana told her son (my uncle) that I was turning 10, so I got 2 10 year old cards for my 11 birthday. That was the bad side the good side is that nana gave me an extra $20 to say sorry. Bad thing, good result.

Anyway speaking of money and expenses, I was practicing my cricket shots without a ball in my lounge, and one time the bat just slipped out of my hand and before anyone could do anything, SMASH, it flies into the the t.v and broke. As soon as it happened I didn't know how to react because both mum and dad shouted “what’s happening down there!” I was really embarrassed and I felt terrible. A day later dad was looking at our insurance policy and he noticed that they had our car registered in auckland for like 10 years, and because of that we got heaps of money back. It turned out we got a new and even bigger t.v with this money!!! Bad thing, good result.

What about the time when you and you family are meant to go to the swimming pool because it's an extremely hot day and you just want to cool off in the outdoor pool,but the outdoor pool is closed and you think that it's horrible, but you go to Mega Air instead. This would be a good thing for anyone who likes trampolining over swimming. Bad thing, good result.

I think this one might be the coolest/best one so far!
It starts off when mum says “we're going clothe shopping” for me this is the boringest thing in the world but then when we get to the mall wherever you go to get clothes is shut. This is what mum hates but then she says “let's just go get a milkshake instead”. That is the ultimate, you miss clothes shopping and get a milkshake, yaa!!! And yes you guessed it, Bad thing, good result!

So next time that you have a bad something happening, just wait, it may turn to a good result.

Science journal 6

Science journal 6 By Ollie and Harry
This week we are learning about flipping frogs, slingshot rockets and projectile launches.

What are flipping frogs:
They are something that you can make out of little pieces of cardboard or big pieces of cardboard. Second step, you get two paper clips, one rubber band, some cardboard, scissors and some tape.
Well Jonty and I made a flipping frog that has four paper clips and two rubber bands because we wanted to see what would happen but in the end it didn't work but it was still a good experiment.

What are slingshot rocket:
Slingshots are something that you can play with when you are sometimes bored.  What they actually are is something that are made out of some straw, some coloured paper or ordinary paper, one paper clip, glue tack, rubber band and a popsicle stick.
What you do with it? Is you can change it if you like but I would probably only change the wings so it can fly straighter than before.
What it does is you pull it back and it will fire about 10 to 15 meters because the rubber band is really strong if you tape it well.

Projectile launcher: We figured that if we put the projectile launcher at an angle of 45° it would go the furthest because it's halfway between straight and straight up and any higher will fall down quicker because what goes up must come down!

Slingshot rocket: The slingshot rockets will go further if you take off the feather papers at the bottom but will go straighter if you keep them on. I think this is because it doesn't have as much stuff interfering the aerodynamic flow. And if it still have them of them on then it will stabilise the arrow and will fly straighter.

The flipping frogs will go higher if the rubber band is tighter, we think this because it will get more power if is straining to much but too much will rip it! So the challenge in this is getting the right amount of strain.

Science journal 5: Trebuchet vs onager. This week we studied the differences and the same things when comparing the Trebuchet and Onager. The trebuchet and onager are catapults that fire mini projectiles like balls the size of tennis balls.

Here are some similarities we thought of. They both launch because of the forces that they generate, for example the trebuchet uses the gravity of the lead weights and the onager uses torsion from the twisted rope (this happens because the ropes want to untwist).

They may have their similarities but they also have differences. For example, the onager has more power so goes further and it also launches quicker but the trebuchet launches slow because doesn't have much velocity.

We noticed the onager launches faster we think this is because it has got more velocity but goes lower. We think it goes lower because the arm is smaller also it goes lower if we pull it to the first hole.

The onager uses holes to launch the projectile further, the furthest will shoot the furthest because it gets more force.

Week 4 trebuchet:
In week for we studied a trebuchet. A trebuchet is a kind of catapult that uses forces to launch a projectile such as tennis ball. We used weight to help the gravity pull down the sling. We noticed the more weights the further the ball went. The main parts of the trebuchet is the weight holder, the sling, the arm and the pivot. I think the Most important part is the pivot because the pivot turns to let the sling release the ball.

Week 3 Rocket Balloon:
In week three we did the rocket balloon again but I was at zones for running. My prediction was that it went longer on the fishing line because the friction was smaller than the cotton on the woolen string (I wonder if that's right). The learning for this is observing and seeing different materials in action, the forces in gravity acting and wondering if it slows it down or speeds it up. I wonder if there was any wind during this experiment and if it made a difference. On the rubric I am relational because I have many ideas and I can make inferences.

We used balloons. We tied them onto a straw and through the straw went a string. The string a number was between two chairs, so when we blew up the balloon and let it go, it went along the string from the air coming out of the air hole. The learning in this was the forces that pushed the rocket balloon along the string e.g wind forces, thrusts and drag. I wonder what would happen if the wind was going the opposite direction and we changed the gradient of the chairs. On a rubric I am relational because I have lots of ideas and can make inferences.

Week 1 Slime: 
On the first day of the second term before school we made slime and inferences about the slime. We used cornflour, water and food colouring. I thought that the best slime would be thick and sticky because it would stick to the victim . We had two batches, one had not much water but the second one had lots and was really runny. Just before we slimed Mr Anderson we had to mix the batches together because it was going dry. The learning was making slime and watching how it changes. I wonder what he hated the most.
