In the first lego league we have finished building our robot with all the attachments too and we’ve started programing the robot as well.
The challenges we’re working on are the filter, the pump and the rain.
To complete the filter the robot has to push the yellow side onto the blue side.
To manoeuvre the robot around we had to use rotations instead because there was no black lines to sense and the objects weren’t close to use the ultra sonic sensor. We chose a starting point in the corner of the map were you can touch the robot and made the robot go forward turn right move forward and turn left until it was lined up with the filter.
We made an attachment that would swing down a barrier and when the robot moved forward it would push the filter so the yellow side flipped over to the blue side.
We decided to build the robot the way we did because it has lots of places to put attachments if we needed to. Also it had barriers to run against the wall of the map. The only downside of the design was it was very big and could run into things if it wasn’t placed right.
The challenges we’re working on are the filter, the pump and the rain.
One of my highlights was when all the challenges worked in one program.
To complete the filter we had to get the robot to push the yellow side to the blue side, for the pump it had to be pushed into place and connect to it’s other part and for the rain the robot has to knock the rain out of the clouds.
On the day we had to get really early and drive up to Melbourne. Here is a video of the day.

Today we went onto a website called NLVM and it let us make own spinners and it will spin it 40 times automaticly and give us the results of how many times it landed of each colour.
This is my spinner.
These are my predictions for the experiments.

Today me and 9 other people were introduced to sewing in design.
Every week 10 students are picked to do sewing with Mrs Watson. This week we are making threads with icons of some of the things we like or wanted to put on there.
We printed out some templates for us to trace on the felt we use to make the icons. We were shown how the sewing machines worked and had a go of sewing two pieces of fabric together to get used to using the straight stitch witch is just a simple stitch that weaves up and down through the fabric and just goes straight forwards. There are two reels of thread in the machine one on top and one bellow the foot that presses on the fabric you are sewing. The one on top gets pulled through the top of the fabric with the needle then after that the needle gets pulled back out again pulling the thread through with it.
Next lesson we will start tracing our templates onto the felt and cutting it out getting ready for our final product.
This session we got out our templates and started to pin them to the felt to keep them in place while we cut around them. I decided to do a few different templates to make it interesting and I might overlap some in different colours.
I managed to get six done this session but I think I might do some more next session and then start on my string of icons.

Today in design I was introduced to Spheros.
If you don’t know what shperos are they are small spheres that can roll around by having a big weight roll around inside it causing it to roll like a hamster wheel. What we were started off doing was giving the a test drive in the “drive” section of the app so you are able to connect wirelessly with Bluetooth and drive the around with that option just to get a feel of what they are like.
After we got into programing and there are three different ways to program we only started with the two and they are draw and blocks. The drawing program we did first. You are able to draw a flight path for the sphero as long as the drawing is connected.
Our challenge was to write our names (connected) and make the Sphero follow it was a little hard to see what the Sphero was drawing but it was clear enough to recognise.
The next thing we did was look into the block programing. This one is different and there is more options and components to it.
Some shapes were set out for us to program the sphero around them. I managed to get through a rectangle and a triangle. The rectangle was quite easy because they all had right angles on them and it was easier get the angle set right because it was 90 degrees. All I had to do was find out the length of the sides. The triangle was harder because the angles were more than 90 degrees and we had to test it until we found the right amount of degrees.
Today we were doing shperos again and this time we were able to make our own shapes or mazes. We could make them trickier to challenge ourselves witch I tried to do to learn more about shperos.
My first challenge was a random shape and I had to program my shpero to go around the perimeter of the shape until it reaches the start again. I learnt it helps to put in a wait block because otherwise the shpero will turn right after it just moved forward not giving it time to lose momentum causing it will swerve all over the place.
Here’s the video of the track.
The second challenge was to make a maze for the shpero to navigate its way around with obstacles to get in the robots way so you have to program the shpero to go around everything. The tricky part of this was to work out how many seconds and what speed to set to make it go the right length. It is a lot about trial and error and learning from your mistakes.
This is the completed challenge.

In scratch this week we were starting on making our first game.
Here’s a screen cast of my first game.
Something new I learnt was how to use a colure sensor so if it touches a certain colure it continue the next command. Also from watching the tutorial it has taught me the basic ways of moving my sprite and how to use x and y.
Hopefully by watching more tutorials it will help develop my skills with scratch.
In session 2 this week we were back at scratch again. Our task this session was to make our sprite dance on a stage using our knowledge of how to switch costumes of our sprite and use the basic movements to make it look as if it is dancing such as moving side to side or facing different ways. To add more effects we could make our own music in the sound tab.
here’s a video of my sprite’s dance.
This session doing scratch we were given a task of making a project only using 10 certain blocks but you’re allowed to use them multibell times but every block had to be used at least once.
Here’s a screen cast of my project.
In this session we were asked to explore other programs to see what you can make on scratch. Some were amazing because they had sometimes hundreds of blocks on compared to ours the were huge. It was really cool to see there programs and try and learn from all the programs although it was kind of hard to understand them.
But I think by looking into these things it can help us to use scratch better than before.
This week in scratch we started of by trying to debug different programs to make them work because before there was a fault in it not allowing it to work.
Here’s a screen cast of the program.
I think by learning to find the different problems may help us with our programs because we be able to find why our program is not working and then fix it.
In this session we were trying to make an interactable program that tells the viewers more about the creator. I made it so if you click on a sprite of my choice that has something to do with my personality it will start taking about that topic until it’s finished and then will switch back background one.
I have made a few different topics so the viewers can learn as much about me as possible.
today I focussed on getting my “about me” project and I did so here is the finished product.
Today I started the 2.0 debug it challenge there were five different programs that we had to debug and I got up to number three. Here is a screen cast of number three.

Here’s a video of my working out.

In maths we have been working on fractions and how hey work so as a way of helping our learning we were given a cheat that all different fractions lined up to see that some fractions are equal with others for example 2/6 is equal to 1/3 this then help us find the simplest way to write down our fractions.
To play it all we needed to do was have to dice that had a number a number on each side so if I roll a 2 and a 4 it would be two quarters or a half. But if you rolled a certain number but you could actually record it a different way that is still equal to the number you rolled. We had o try and come up with something really interesting about how the fractions line up and all the different ways and still be able to explain it . I think that this is a great exercise for helping us understand how to make fractions easier just by thinking more.

Today the whole of year five visited Keith Humble Centre to finally perform a few pieces that we had been learning on our instrument for about a term and a half.
The experience was really amazing and I think it’s a great way to show how much we have learnt over the past few months. We spent most of the day practicing and revising our pieces that we’d been working on to try and completely polish of our performance. But at the end of the day we were finally allowed to have the chance of performing the pieces to our parents or family to show them just how much we have learnt over this short amount of time.
I really think that it was a complete success and a great way to show of our new skills and I’m really happy that year five have this chance to learn something new I think we’re very lucky.

Today in maths we exploring geometry in micro worlds. So if you don’t know what micro worlds is it’s an app with a whole range of different things to do on it such as drawing pictures and animated scenes, presenting things and much more but today we were doing turtles and geometry. Turtles and geometry is basically where you have a turtle and write down programs to give it instructions or commands to make it do something. But today it is not actually about commanding your turtle but learning about geometry. On the app there is a command that is called pd witch mean pen down so it means you can draw shapes with the turtle to learn about geometry.
When we were on the floor we were drawing a trapezium on micro worlds and discovered that on a trapezium the four angles on it swapped the degrees on the inside and the outside angle each time. Because we went forward 100 then turned right 67 degrees went forward 200 then we had to work out how much to turn next. So what we did was we degrees worked out how much it was to 180 witch was 113 so it meant we had to turn 113 degrees. Then we moved the turtle forward to reach the end but I think you get the idea of the angles. Just in case here’s a photo of my own trapezium.
In micro worlds today we were given the challenge of trying to make the anitals with the turtle just by drawing it with the pen down command.
We would have to make a procedure that the turtle could understand and follow the instructions. Mine are J.W so I had the challenge of having to make a curved shape but with the knowledge of how to make a circle in micro worlds it helped me a lot.
But that’s not it, not only were we supposed to draw our anitals but to and draw it in block writing as well so we had to do a whole other part to it. The first letter I drew was J witch was easy to start of with because all I did was draw a straight line and add a semi circle onto the end of it witch has the same commands as the circle but it only repeats it 180 times.
but as soon I got the block writing it got hard as I didn’t know how to do the other semi circle because it was going to be smaller than the original one. So I tried experimenting with how much turn and distance but it would either make it too big or would end up making a full circle. Then I tried instead of having 180 I tried 90 because it’s half of 180 and I only needed a small dip in it so it would be perfect and it was so that was the real challenge. But I didn’t get time to start the W so that’s what I’ll be working on next lesson.
This session we were back doing micro worlds but this time we were looking into how setpos and the cartizien plain works. If you don’t know what he cartiezien plain is it is a tool used to help locate things or draw maps and other things too it basically the thing in battle ships that’s used to locate your enemies.
So we were using it as a command for the turtle to tell it where to go without putting in a bunch of commands just for it to get to a certain area. We would do this by using setpos witch is basically a cartizien plain. To measure the cartizien plain it is split into four different parts the bottom left corner is negative negative and the top left corner is negative positive, the bottom right corner is positive negative and the top right corner is positive positive. We used this to make lots of different shapes in different places of the plain. I think it could quite useful in other projects to come in micro worlds.
