  Slimming mr Anderson.
At the start of the term some of the classes made slime so we could slime Mr Anderson at Monday meet up. Our class experimented in the end we made the slime with water and corn flour which is actually called Oobleck. When we poured it on top of Mr Anderson's head it ran down his back so you could easily see that it had water in it. Our slime was green and it smelt like snot. Our class made two batches but the second one was way more watery so we mixed both of them together. I think that good slime should be not too runny and not too hard, because if it is too hard the slime won't even come out of the bucket but if it is too runny it will come out of the bucket too fast. The learning in this was that if you mix a slime that's too thick and a slime that is too runny together it makes a good constituency for slime. On the rubric I sit at multi structural because explain what I learnt and how he slime smelt and what I think it should look like.

Rocket balloon
To make the rocket balloons we had to get two chairs, tie a piece of string between the chairs, get a straw put it on the string, tape the balloon to the straw, blow the balloon up and let it go and it goes across the string. This happens because of the forces (such as thrust, gravity, drag) of air in the balloon so it goes across the string. I wonder if changing the gradient and doing the experiment on an angle, if it will make a difference? The learning in doing the rocket balloon experiment is that you need to figure out how the balloon goes across the string . On the rubric for the rocket balloon experiment I am sitting on multi structural because I have many ideas on what to improve.

Rocket balloon
Week 3
In week 3 we did the rocket balloon experiment again but instead of wool string we used fishing wire. I reckon the difference between the two times we did the experiment was that with the fishing wire the balloon went across a lot smoother. I predict that the fishing wire is smoother because it has less friction. I wonder if you did the experiment on a piece of ribbon, if it would go faster? I saw that the balloon spun as it when across the string, I think this is because of the wind.
On the rubric I am sitting at multistructural because I have many ideas about the rocket balloon and how to improve but I don't know how to teach others.

Trebuchet
This week we have been learning about projectiles (such as trebuchet and onager). A trebuchet is a type of catapult that has weights at the end of it, and when you pull a string it flips and fires.
An onager is kind of like a trebuchet but it is a bit smaller and it has a smaller stick then a trebuchet.

Science journal 29.6.17   - Week 9

This week we are looking at three different types of projectiles. We have made a slingshot , flipping frog and we learnt about an angle launcher.
For the slingshot we observed that when you take the feathers off the slingshot, it will go further but if you keep the feathers on the slingshot then it doesn't go as far.  We think that is because it uses a lot of drag.
For the flipping frog we noticed that the rubber band had to be really tight and the cardboard had to be strong otherwise it would bend and it wouldn't work as well. Sometimes it would also break.
For the angle launcher we observed that  at 45° makes it go the furthest and 20° is the shortest.
Our conclusion is that the best is the flipping frog  because the most enjoyable to make and it not as confusing. The reason we didn't like the rocket as much because it is a bit complicated to shoot it but with the flipping frog you just fold it and it jumps.

20.6.17 science Journal
         Week 8
 This week we studied the Trebuchet and the Onager. We noticed that there a some differences and similarities.

Here a some similarities that we noticed while we were studying the two catapults. They both propel the ball forward, they both use fiction and thrust. We recorded this data by using a compare contrast map. We also collected some data by using a chart. While watching this I have picked up on the fact that the Onager’s arch is smaller than the Trebuchet because the Onager’s arm is smaller than the Trebuchet.


We recorded that the Trebuchet goes further because the arm is longer so it uses more forces, but the Onager has a much smaller arm so it doesn't use as much. After the Onager fires it uses torsion and swings back and forth, this creates friction when it rubs across the ground.




My conclusion is that the Trebuchet would be better for in the olden days because it would be able to get over most of the castles easier because it swings  and the arm is better and longer.

Inquiry reflection




In He Tangata this term we have been focusing on being a responsible citizen.

Elise and I decided to do a project on teaching year 4s, 5s and 6s how to look after a pony.

I think I am relational because I know what to use such as saddles, bridle and halter, and why to use them. I don't know how to put them on, but I can still teach people a few things.

I am proud that there was a big amount of people who were interested in learning how to look after a pony. I was also proud with the amount of time we spent preparing our project.


My next step is to learn how to dress the ponies with the appropriate equipment, such as halters saddles and bridles. If I learn how to do this I can go to extended abstract because I will not only be able to talk about it, but will also be able to do it.
