Sewing

Today The seventh of august i got picked out of 5 from the robotics group and 5 from the scratch and for the week we where to do sewing for the week. I had never done sewing before and didn’t know how to use a machine. The first few days where practising to use the sewing machines and to do straight stitch but what is straight stitch? Straight is a stitch witch is just stitching forwards with a straight line. It is mainly used to stitch two things together.

Then that we knew how  to sew with a machine we where given the task to find and print some templates of things that we where going to make into a pattern here is a stitched pattern.

with the templates we had to trace them onto some felt and cut the felt out into the shapes we chose. I chose a circle and some different types of stars. Then using a strait stitch we stitched them all together like the image above.  This was great fun and i loved learning how to sew and sewing my first few pieces of felt and altogether great to do.

scratch

Today 4th of August i finished the week of scratch this week we had to make an account, make a sprite dance, only use 10 bricks and created a studio i was put into the other group which was scratch from Lego robotics to learn about my Lego robotics here is a link to my Lego robotics copy and paste onto the internet tab to see it :

Here is me explaining what i did for the dancing project :

scratch dancing screen cast FFS-1f7a46m

It was great learning how to make my guys dance and to put music in my project which i think will really help with my learning of scratch. I also did a project where i was given 10 different blocks and had to do something with them but i could use them as many times as i want. eg. i could use move forward 10 3 times. here are all the blocks i could use

– When this Sprite is Clicked
– Repeat X times
– Wait X seconds
– Play sounds until done
– Set size to X
– Hide
– Show
– Say for X seconds
– Glide X secs to X:— Y:—
– Go to X:— Y:—

Here is mine

I learnt how to make a project with a limited amount of blocks i loved having limited blocks and challenging myself and i can’t wait for next lesson.

 

 

 

 

 

 

 

 

 

Lego robotics

Today Friday the 28th of July half of year five was put in a robotics group for a week and a scratch group the next week and the other way around for other half. I was in the robotics group and our challenge was to a go around a strait line and a circle by going left then right on a black line. Mine sadly didn’t work because i missed the first session  only had one session. here is a video of my first attempt:

WIN_20170726_15_00_32_Pro-1bxua0e

I have changed my program bur i didn’t have time to test it so it may or may not work

here is a photo of my program :

 

It is supposed to go right till it sees the black line then left then right etc.

I learnt how to use the forever block which makes the program inside it do the program forever . and also the switch block which makes a decision depend on what your two answers are mine where if it sees black turn right but if not turn left.

I loved the robotics week and learnt a lot.

Melting pot reflection

Melting pot is an awesome book about a kid called Edward and his father is Chinese and his mother is European. He has a hard time at school being picked on by bigger kids because how he looks different and because the other kids parents are ignorant and that means that they don’t get what the Chinese ways are. But when his cousin Elizabeth comes over to do the jobs around the house it all gets worse for him. she is being racist and mean because he is half-Chinese. But then Edward finds out that she is parroting the words of her father he is really surprised. Her father does not accept Chinese and say they “should not be here because they are not good enough” and their are better people. the immigration law is a rule that not naturalised Australians can’t come from China his father is trying to change it. Edward has to go to china to meet the rest of his family but will he be able to return? This is a great book and can teach you a lot about foreign country’s like China. I would recommend this book to anyone interested in learning about another country. out of 5 stars I rate this book 4.

Origami fraction pinwheel

Today 14 of June 5c had to make and Origami fraction pinwheel. What is an Origami pinwheel ? An Origami pinwheel is a square with some fractions and it had 3 different colours Yellow, Red and blue . In it and we had to find what fractions each colour has. We can fold the quarters to make different patterns with different fractions of each colour. Here is my origami pinwheel:

Here are my other folds I did:


 

 

 

 

here is a link to a video of the top image and each fraction and colour:

fractions 1 fixed-1nsyb7m

I learnt that there are a lot of ways to make equivalent fractions and 1 simple fold can change a lot of numbers. I loved making Origami pinwheels although they where a bit tough to make I love playing around and learning fractions at the same time.

 

Allegro day!

Today Monday the 29th of may year 5 where taken on a great trip to the Keith Humble centre to share our  musical instrument most of us started a new instrument at the start of the yet but some of us had already learnt and have private lessons. We could chose from trumpet, trombone, clarinet and flute I started learning the flute at the start of the year and I have had a great time so far.

It was a great day and all the parents where invited to watch us play our instruments. Most of the day was spent rehearsing and practicing. We all did great performance and had a great time playing our chosen instruments. The day started by us rehearsing and then we went out for recess. Then more practising and then we played a game with our instruments where each instrument had a different rhythm. We had to listen then place the cards with the beat and with do, ray, mi, so, and la and we had a scoreboard. The winners where the flutes so we won.

Kites investigation

Today year 5 were given the challenge to get into a partner and to find the degrees of each angle of a kite.

Here is a video of our kites investigation:

angles investigation FFS-2hrvm6z

I learnt that 2 45 degrees angles = a right angle which is 90 degrees.I learnt that in a kite the obtuse angle is 110 degrees. I also learnt that the top angle is 90 degrees angle is a right angle. I learnt that all quadrilaterals angles have to =  up to 360 degrees.

 

Lego robotics!

WIN_20170609_12_45_03_Pro-1rj9cyksreen cast movie maker trimed FFS-vfmpj9Today in Design, year 5 had to start our Lego robotics unit. The aim was to create our own program to perform a chosen task.

What is a program? A program is a script that you can teach a robot to do. For example, I made a script for a robot to perform a hi-five.   The script looks like this –  elevate right leg 10 cm, move right leg forwards 20 cm then lower right leg 10 cm then instead of doing it over and over and over again you could change the right leg to left leg then repeat.  Then the script would say elevate right arm 90 degrees and step.

Then we were put into groups and taught about the building of the Lego Robot and that the most important piece was the piece that you would put the script in with the battery that we would need to charge each night.  Mr McKie taught us about the program and that we would need to build a Lego car to perform the program. My group are nearly done building the car to program. I learnt a lot from the first session, like how to program and that you could even program Lego to move. It was a great first session and I can’t wait until the next.

Here is a link to a time lapse of us building the car:

How will robots help us in 20 years?

The challenge

Today year 5 was given the challenge to use the three ways of moving our lego robots between 2 lines and back. The three ways are seconds, rotation and degrees. seconds is that you tell the robot for example to go forwards for 3 seconds and then turn for 1 second and go forwards for 3 again. Degrees is how much your wheel spins for example 1 spin is 360 and 2 wheel spins are 720. The other way of movement is  Rotation is the same as degrees but you write how many time you want the wheel to rotate for example rotate 4 times and then turn left for 1 rotation.

here is my program

screen cast movie maker trimed FFS-vfmpj9

The first yellow block is the start block that you need for the robot to start. The red motor is what type of motor you are using. The arrow is what degrees its going at. The speedometer is how fast it goes. And because I have it set on seconds the timer is how long it goes for. The play button means that it will stop after its done. The B+C in the top right are wich cable points the cables have to go in. I found out why it wasn’t working it wasn’t because of the degrees of the turn but because I had it set on that the wheel would turn but I was supposed to have it set on seconds. So I changed it and it worked.

Today Friday the 9th of June in design year 5 where introduced to the 4 sensors on our lego ev3 robot The first one was the touch sensor, The ultrasonic sensor, The light sensor and the gyroscope sensor. The touch sensor works if you put it on your robot and connect it to it when it hits something it will do something for example when it hit a wall I will turn 90 degrees then go forwards. the ultrasonic sensor sends sound waves and when they come back to it. It measures the distance away from the robot. For example I could say that when it get 3cm away from an object turn left 60 degrees then go backwards for 3 seconds. The light sensor is a sensor that detects how much light frequencies come back because it sends light out and detects how much comes back for example if the colour its on is dark like black not as much frequencies come back because dark colours like black absorbs the light so not as much come back but a bright colour like yellow reflects the light and more frequencies come back. The gyroscope sensor for lego robotics is a sensor that can measure the degrees of fall from -440 to +440. For example when it get to a 20 degree fall slow down from 100-50 so it doesn’t tip over. Like when you are walking down a hill you slow down so you can keep balanced and not tip. Here is a video of my first attempt of the light sensor:

WIN_20170609_12_45_03_Pro-1rj9cyk

It didn’t work because I had it set on seconds which means that the robot goes for a set amount of seconds but then I found that I didn’t work because I needed to set it just to on so it goes for ever till it hits that colour and then does the next think I programmed it to. I also learnt a new block to use it’s called the wait block it’s when it hit the colour it will wait then do something. I finished the around the table and around the stool I also needed to finish one where I had to do to 2 on the baseball diamond and back to 1. I finished them all. Here is a link to the half way and back to 1:

Here is a link to the whole baseball diamond:

WIN_20170615_08_54_54_Pro-1ac0upm

Touch sensor 

Today I started  with new sensor it is called the touch sensor. The touch sensor works if you put it on your robot and connect it to it when it hits something it will do something for example when it hit a wall I will turn 90 degrees then go forwards. our first challenge was to make it goo forwards hit the wall and then stop we had to use the wait block this time.

here is my programme for the hit the wall and stop challenge :

here is a link to a screen cast on what all the parts do:

screen cast touch sensor 1st-r1tru1

so I completed the first challenge and here is my robot doing it:

WIN_20170620_13_17_01_Pro-1fpiwkc

I also completed another challenge which was one where I had to programme it to hit a wall go backwards and then right turn 90 degrees. I finished that one but didn’t get a video of it working.

sc hit wall back then 90-2ab8ixd

I loved learning about a new sensor and I am loving learning new stuff to do in ev3 Lego robotics. I am loving ev3 Lego robotics so far and cant wait till next lesson.

this session we where introduced into a new sensor the ultrasonic sensor sends light waves out and when they come back to it. It measures the distance away from the robot. For example I could say that when it get 3 cm away from an object turn left 60 degrees then go backwards for 3 seconds. The challenge was to get 10 cm away and then come back so here is my programme:

Rube Goldberg machines

Session 1

Today year 5 was given the task to make a small Rube Goldberg Machine. What is a Rube Goldberg machine? A Rube Goldberg Machine is a chain reaction of simple machines which is complicated to do something simple. We had to put paper in the bin. We were split into groups and had to plan, design and build a complicated Machine. My group had some ideas like a bucket on a pulley or some dominoes. We didn’t finish in the time limit but we had 2 simple machines. They were an inclined plane and a pulley. The marble went from a ramp to a pulley and then hit the paper into the bin. I learnt that an incline plane, a pulley, a lever and a fulcrum is a simple machine and I learnt that a Rube Goldberg machine often never works on the first time and can get really frustrating.

Session 2

Today the first of May, 5c had to make some pulleys to lift some marbles which will help us to put in our Rube Goldberg machines. We where put into partners and was given the challenge to build a pulley and it had to lift 5 marbles. What is a pulley? A pulley is a simple machine lice a inclined slope or a lever. it is like a winch and is used to lift thing that are too heavy for humans.  Here is a image of the pulley we made.

It is made of string a thread ,metal and a yogurt tubs or aplastic cup.

I learnt that a pulley is in a lot of everyday things like a blind or a flag pole. it was fun creating pulleys and seeing witch one of the three types of pulleys most easily lifted the 5 marbles. we only did the single and the double and didn’t have time to finish the quad pulley.  It was a great learning experience and I thing it will greatly help us in our rube Goldberg Machines.

Session 3

Today the 2nd of may 5c did another mini activity to help our Rube Goldberg machines. Today we where using Lego to build a chain reaction of simple machines like inclined plane and lever. we where in groups of 3 and had our own part separated throughout the class. Our group where given the task to build the Zigzag part of the Rube Goldberg Machine. Here is a link to a Times laps of us building the Zigzag part.

I learnt that Lego could be made into a awesome Rube Goldberg machine. It was a awesome time building the lego to help our knowledge in Rube Goldberg machines.

Session 4

Today year 5 did another simple machines activity this time it was K’nex and we got a book and had to pick what to build.  My group was going to build a conveyer belt. It looked hard and it was but once we finished we where really happy. it was really fun and we had some great ideas to take into our Rube Goldberg projects. I was proud that we finished and was raring put some ideas into our Rube Goldberg machines.

Here is a image of our K’neks conveyer belt :

It was awesome and I learnt a lot that you can do with K’nex and that they can be great to use in Rube Goldberg machines.

Here is a time laps of us building:

rendered conveyer belt-19dmmyx

session 5

Today we had to join our three simple machines together to build a Rube Goldberg machine. we put our Lego Zigzag at the start because we thought that it would be better to start high to gain more momentum to go into the machine. we noticed that we couldn’t use the conveyer because it didn’t work by its self and we needed something that would walk by it’s self. We changed it into a dump truck so we could use the front to hit something and the wheels will help it roll. we thought that it could start at the Lego Zigzag into the dump truck which bumps into a marble which then dropped into a pulley which lifts a marble and the marble rolls over the finish line. We didn’t finish but we only needed to build the pulley. it was great to try joining our simple machines.

session 6

This session we started designing our Rube Goldberg machines. Our groups aim is to put the marble away into a box. Our three simple machines are a pulley, wheel and axel and inclined plain. We explained what all the parts we need and why we needed them and also where it goes and what it does. We also designed what it will hopefully look like the finished product. The explanation is what  it will do. The explanation is We push the wheel and axel  down a tube and it hits 3 dominoes which hits a marble into a pulley which comes up to hit 3 more dominoes which hits another marble into a box.

Session 7

Today my group started building our Rube Goldberg machine. It was fun and exiting to start building our Rube Goldberg machine and the first thing we built was the inclined plane. We use thesauruses and had a cardboard roll we cut in half to use as an inclined plane. We also built the wheel and axel to roll down the inclined plane which hit some dominoes into a golf ball.

Session 8

Today the  29th of May We continued on with our Rube Goldberg machine. We built the pulley with tin cans and string. We Also got the rest of the dominoes. We placed our inclined plane then we placed the pulley between the two tables and made it so when the golf ball in the pulley it will move and set dominoes.

session 9

Today we had to move because the tables we where using where used for something else so we moved tables but didn’t have to change our machine. We sat the 4 dominoes from the pulley on the pipe to the come around and go into the box so when the golf ball goes into the pulley and the pipe moves across a bit and hits the dominoes. Here is a link to a video of our Rube Goldberg machine working:

WIN_20170615_12_57_49_Pro-2ir0zil

The next thing we hope we are going to do is finish our designs.

Session 10

Today was the FINAL day of Rube Goldberg and we had to finalise our design and make a final video about our whole project. First I finished the design which I redid to fix it to the actual build. Then it was onto our final video. We put lots of photos, videos, captions and effort into the video. Here is a link to our final video:

rube golberg final vid 2 FFS the 1-2n8nrg4

I learnt a lot from this unit like what simple machines are, what Rube Goldberg Machines are, who is Rube Goldberg and lots more. Here is a link to who Rube Goldberg is :

Rube Goldberg Archer-1rt2oad

Once we were finished our machine we had to show it to our parents and to a year 4 class. I loved the Rube Goldberg Machines unit and learnt a lot which will help me at lots of things like building and forces.
