Melting Pot Review

June22

Melting pot is a book for people that like to read the past. It is a great book about a boy called Edward and his Chinese name is Chek Chee. His dad is Chinese but his mums Australian so at school he is bullied because he’s part Chinese and part Australian. Through the book he knows he must go to China he trays his hardest to stay in Australia. Melting pot is a book for people that like to read the past. I think this book is about a 3 because of how much I learnt about the gold rush.

Origami Fraction Pinwheels

June15

Today in maths year 5 were given a peace of paper that looked like this

We had to get all four corners into the centre were the white is. This is how you got all four corners into the centre. How to make Origami Pinwheels

we were then told to fold the two reds, the one yellow and the one blue in half in a clock wise direction so it looks like this

We were then asked what fraction were the colours now: I thought that red was 2\8 blue is 2\8 and yellow is 5\8 we were then asked to flip them back to normal and then in a anti clockwise direction. Once again we were asked to show what fractions the colours were: red is 3\16 blue is 8\16 and yellow is 5\16.

We were then asked to mix it up now so some went anti clockwise and some go clockwise here’s a little show of what I made and what the fractions are.

Rube Goldberg Machine

Designing

Todays the day my group could get start on designing our Rube Goldberg machine. Here’s a video of me working Rube Goldberg Design-1dn326b

 

Building

Finally we could get started on our rube Goldberg Machine, I had brought in some marbles and another group member brought the rest. At first I got started with making the pulley so I went to find some string a sewing thread and two yoghurt containers. While I was building the pulley another group member was making a ramp that the car stars on, and another member was trying to get the marble to stay on the space bar and trying to get that working. At we spent some time joining it all together. Most of it worked all we needed to do was get the music part working.

Today my group started of telling what we did last time when I was sick. They decided that the pulley wasn’t working and broke to much and changed the pulley with a lever. How our Rube Goldberg works now is- someone pushes the space bar- the marble hits the car- the car hits the truck- the truck hits the lever letting go of the marble- falling through two tubes, and that’s what we’ve made so far.

 

Simple Machines

Simple machines

Today we were told that in three different design lesson we were going to make three different simple machines : Mrs Watson was teaching us how to make simple machines out of Lego, Mr Colbert was teaching us how to make simple machines out of Knets and Mr McKie was teaching us how to make pulleys. Today 5C was making a pulley. I was in a group of three and we firstly had to grab a short bit of weak wire that would be easy to cut. My two members grabbed some scissor and string to pull on one side and the cup they grabbed will be tied the other end. We had a sheet of paper that had one pulley, a two pulley and a four pulley. The first pulley you made was the one pulley, which was simple because all you had to do was, tie the wire inside the pulley and then grab the two sides and shape them into a hock. Then rape the string around the cup and slide the other end through the middle of the pulley and the hock. and then all you need to do is pull on the other end and there you go.

one pulley-2i97w6j

Then we had to make the two pulley that wasn’t to hard all you needed to do was rape the string through the second pulley and you would usually use two pulleys is to pull something heavier.

two pulleys-1kmt48y

We then had to figure out which pulley was easier to use I thought the first on was easier because (my reason is in the video below)

interview-1xgat5y

In the end we didn’t have time to make the for pulley but now 5C know how to make a pulley.

Last session we were making pulleys now were making simple machines out of Lego. I was in a group of three meaning we had to build something more complicated.

(this is what we were making)

So as you can see its very colourful, that’s because its just something you make at home with a tube full of Lego your the scuba diver. So my we started of with the bottom layer and someone had to find as many of the one piece as they could. I had to find 4 by 2 pieces once we had done that we had to make 4 different tawers I had to make one Another group member had to make another and the last group member had to make 2 others. This is us connecting the towers and the bottom together. rendered Lego-2ndt286

Today we had to make a simple machine out of Knex. My group of three decided to make a elevator which had a pulley. So what we had to do at first was gather the pieces that we would need, we then needed to connect them together to make the outside. Now we had to make the pulley with the part that you stand in when your on the elevator. All we had to do is connect it all together and it should look like this.

What is MicroWorlds

MicroWorlds is a app where you program a turtle to, make shapes, moving objects and random things that you can think of.

Fd-move forward

Bk-move backwards

Rt-turn right

Lt-left turn

Pd-pen down/need to use to draw

Pu-pen up/if you don’t feel like drawing something

Home-move to centre of the page

Cg-clear graphics/if you want to restart the page

These are the main programs you need

micro world explain-2efqp5l

Session 1

Today we got to start using MicroWorlds (well we played around with last year too). All we had to do was make some shapes, which I think is really fun. These are some of the shapes I made and how to make them.

Session 2

Today we were told to make a quadrilateral and prove all the degrees on the angles.

micro world explain-2efqp5l

Session 3

 LM-1hekmbo

 I found it hard to make the M 3D/bubble

Today we had a new challenged, we were taught what a Cartesian plane was and it’s like a square split into quarters. If you play Battle Ships when you say, A 3 that’s a Cartesian plane but instead of saying, A3 you would say, -1 -3 if you were in the bottom left corner, if you were in the bottom right corner it would be 1 -3 and in the top left it would be -1 3 and finally in the top left corner it would be 1 3. So our new task was to make a Cartesian plane and make a different shape for every corner.

This is me making the Cartesian plane and making the shapes in all four corners. carplane video

Kites

May15

First Task: On Friday 13th of may, 5C had to try make a kite out of a rectangle shaped piece of paper. Some of us got really close to making a kite one made on the others struggled. I was close but didn’t get there. Now that we had a try Mr McKie showed us how to fold a piece of paper into a kite.

first step:fold the top right corner until it reaches the left side

Second step: fold the bottom right corner to the same position as before

Third step: flip it around fold the top right corner until your piece of paper looks like a kite

Now we had to make a second one (just the same three steps).

Second task: Now we grabbed our scrap book and traced our kite in our book. Once we had traced the kite we had to estimate the degree of all four angles. My estimate was the acute angle at the bottom of the kite was 50 degrees, the right angle at the top of the kite was 90 degrees and the two obtuse angles on both sides of the kite were 110 degrees. We now had to find a partner and figure out the degrees on all angles. Me and my partner then joined my two kites together and then we realized that joining both acute angles together made a right angle so separating them made two 45 degreed angles. So now I now that the acute angle is 45 degrees meaning that the obtuse angles couldn’t be 110 degrees because a quadrilateral always ad up to 360 degrees. When then had to find out what the obtuse angles really were.

kites-quh2zf (this explained how me and my partner figured out all the degrees)

So the Right angle was 90 degrees, the Acute angle was 45 degree and the obtuse angles were 112 and a half.

Lego Robotics

Building Process

Today year 5 started Lego Robotics. We were divided into groups of three, one kid from each class. We were then told the number and find our robot. I was number nineteen so our group met up at robot  nineteen. this is what the robot looked like so fare.

I then grabbed a Lego manual that we needed to make the rest of the robot out of Lego.(group member making part of the robot.

So how we organised things were I would grab the pieces for one page and they would build it for that page, then the next page they grabbed the pieces and I built what was on the page. Firstly we needed to make to of these,

 and then connect them together like these. In this lesson I learnt that not every Lego set is completely made out of Lego.

We had fifty minutes to complete our Lego robot and mainly spent the time looking for Lego pieces to build our finished robot. While we were looking for this one Lego piece about four other groups were to and they had ran out so we had to look in a couple of boxes with random pieces in them until you found two of them, and I got so exited when my teammate found one then my other team member said we need to find one more and I was so annoyed.

I learnt not to look in the one spot for something and to look in different Lego boxes.

Drawing robot

Today we had to draw all the sides of our finished robot. It was quit easy it just took a wile.

Lego robotics-2025hjt <-this is me drawing all the sides, but the top one I forgot to film

challenge 1

Finely we got started on programing our robot. The only things we could program it to do were, movie forward, move backward, turn left, turn right and play some music. This is how to program it to go forward.

Lego robotics how film-zjjuo0 This is how to use the steering program

Back to building process

Today I had to deconstruct half the robot because I had to find out why one wheel wouldn’t move. Turns out we didn’t quit build the robot right and one piece was joined with the motor so the part of the motor that turns the wheel wasn’t moving because of one simple part.

programing

Today was only a short because we had sports on but sadly my computer run flat so I couldn’t program but it was fun watching my other peoples robot.

Finally I could start programing. The night before I had created the programs that I thought would move succeed, the programs should make the robot move forward and backwards using degrees, rotations and seconds.

SECONDS: Means how long the robot moves for

ROTATIONS: means how many times the wheel turns 360 degrees

DEGREES: how many degrees the wheel turns

seconds-147u5iq I found this one the easiest because all you needed to find out is how long it takes the robot to go from on place to another.

rotations-1g00vit I found this one to be easy too but it was hard to figure out how many times the wheel turned

 degrees-1e69key When I was doing degrees I realized degrees and rotations was the some just one was 360 times how many the other was

After we had finished the first task we had to program our robot to go around in a square like a base bowl player. This is what I thought would work How to sqaure-ti86xl Tis is the video of it working base bowl-20biyqw

Today we were given a new task. We had to program our robot make half a circle and come back to the start. How to semi circle-1l11dwb

Robotic question

May7

 

What is a robot?

A robot is a complex machine that can do a simple job but sometimes the job is more complicated then the robot itself . Robots could do something as simple as chopping down a tree or it could make something as complicated as a car.

What is needed to make a robot work?

You will need moving parts and a computer to program those moving parts to  make the robot walk and move around.

What is a program?

A program is a series of codes, like stairs. To make a robot or machine move around, talk to someone, shake someone’s hand or even make lolly’s.

Why do you think people invented robots?

I think people invented robots to do dangerous jobs like, disarming bombs. People also invented robots because they’re more efficient they don’t need to be paid, they don’t need to take lunch brakes they don’t need holidays and they can’t get sick like people.

Angles Investigation

April30

Today we had a session in maths about angles. There are five different angles; right angle, acute angle, straight angle, obtuse angle and reflex angle. We went on three different web sites that our school has made about angles. Firstly you had to find a partner. When we had found a partner we than went on the first website and played around with it. The red side of a semi circle was 90 degrees and the blue side was also 90 degrees.

We then had to change the angles and guess what both angles were. You had to hold down your mouse on the hand and move it around to change the angle. When we had a estimate we then used a 180 degree protractor to check if our answers were correct or close to correct. To use a protractor you first have to line the 0 and the 180 on the line you are finding the degree on, and then follow the other line and there will be some numbers on the top, you look for the number that the line is on and you have your degree

 

What I Learnt

I have learnt how to use a protector and how to the angle by either how close it is to 90 degrees, 180 degrees or 0 degrees or if its close to the middle of 90 or in the 90 degrees to 180 degrees.

 

Rube Goldberg

April30

Friday 21st April: Today we were sorted into groups of three to work on a Rube Goldberg Machine.  This is a type of machine that is complicated but does a simple task where something has to go from one task to another in order to achieve a result. For example here is a picture of one (see below) where a person using a fishing rod to trigger an series of events that leads to the TV being turned on.

Everyone’s group had one person from each class. Once our groups were determined we gathered to work out what we were going to do.  There were three people in my group. We all shared our ideas and wrote them down on a big piece of paper and worked through each idea until we had our project decided.

The aim of our project was to push a piece of paper into the bin.  We decided to use six steps to aim.  The first step was to roll a marble down a ramp that would knock into standing dominoes. The second step was the dominos falling forcing a domino into a funnel, which was the third step. The falling domino would be guided by the funnel to fall onto a ramp that was the forth step.  The domino would  drop down the ramp into the fifth step, which was a car.  The car would move and knock the sixth step which was a ruler bumping the piece of paper into the bin.

One of my group partners made the platforms that we would need out of Lego while I went with my other group member to find the other pieces that we would need. We needed a marble, dominos, Lego for the ramps, a car, a ruler, a piece of paper and a Bin.

First we had to try out the first and second step to make certain that these two parts worked. We tried it up to ten times to find out if the dominos could be forced into the funnel by the marble.  But they couldn’t because they couldn’t stand up on the Lego and would fall in different directs each time the marble hit due to the bump surface.  Back to the drawing board.

We decided to get rid of the domino step as it didn’t work and was wasting time.  Our second attempt was to drop the marble onto the ramp to get the marble to fall the funnel.  The marble would roll down the ramp but would then reach the Lego platform and roll off the edge.  I went and got some long piece of Lego to stick along the edge of the ramp creating a fence to prevent the marble from falling off. It worked as far as hitting the car.  But even though the marble pushed the car it didn’t hit the ruler.  So we changed the position of the ruler so it was a bit higher and we were hoping that the cars wheels would hit the ruler and the car would fall into a little box out of the way so that the ruler could hit the paper. We tried the changes and found that sometimes the marble would hit the car but the car wouldn’t roll forward enough to hit the ruler.

We then moved the whole machine closer to the edge of table and moved the ruler up closer to the car and then the piece of paper sitting in front of the ruler. Success. It worked.

Rube Goldberg success
