MICROWORLDS kites

‚Äĺ¬įIn MicroWorlds we have been making kites. we had to work out how to program it to do a kite. Here is a picture of the programing

                                         It took a while to work out how to make the kite but we managed.

The next lesson we where given four pieces of A-5 paper, we were puzzled! The teachers showed us how to make a kite with the paper! Here is a picture of one of the kites below.

¬†¬†¬† This is the kite marked with the degree’s of the angles.¬†The challenge¬†was¬†to¬†¬†work out the angles without using a protractor!¬†The trick was to use the other kites. We knew that the black marked angle was 90¬į so we lined up the¬†small angles and found out they were 45¬į! we used the same method for the 110¬į ones!!

Making the kites was so fun and I learnt a lot !!

Hummingbird

The past three weeks we have been doing Hummingbird, which is really fun. Hummingbird uses a circuit board and has multiple motors, sensors and more!

Our first task was to go on the Hummingbird website and do some of the projects it had to offer! The first one we did was to make a vibration¬†motor vibrate, to do that we had to put together a program. This is a snip of the programing!We also got a light to turn on and with a little¬†more programing we got three lights to turn on!¬†Hummingbird uses a board to plug in all the lights, sensors and other things. At first I couldn’t put anything in the board so I was pretty useless but luckily I got the hang of it! the picture below¬†shows the programing to power one light.

The next¬†challenge¬†we did was try to make a vibration motor and a single colour LED to work at the same time, turning on for four seconds and turning of for four seconds and do it five times! We first tried to put together a program but it didn’t do a thing. Wondering why it didn’t work we seeked assistance. First we asked our friend but they had no¬†idea, we asked a assisting teacher and they said to ask ‘some good programmers’¬†(¬†boys )¬†. So we asked them, same thing no idea!! After that the teacher was asked and looked at the program and said” you have got them in the wrong ports” great all of that for some ports! We put the vibration motor and the single colour LED in the right ports and… pronto! it worked. Because it took us such a long time to get that working we didn’t get to do any more projects and we also missed out on doing our own project which was extremely¬†sad!

I found Hummingbird really fun and really Educational.¬†It was sad that we didn’t get much done but we did something!¬†I would love to do Hummingbird¬†again and explore all that it has to offer!!!

Robo Cup

In the past two weeks we have been preparing for Robo Cup, we had the opportunity to join and I wanted to. What we had to do was make our robot follow a course with a curvy black line on it. I found it really hard to program my EV3 to go through the course without it going off the line! Every board we go over earns us ten points and each time the robot goes off the line you lose ten points. To complete the course without it going off and randomly wheeling around was to make the robot re-adjust itself every time it went off the line, underneath here is a snip of the programing.

This program asks the line sensor a question ‘do you see a black line’ if the answer is yes the robot will keep on going forward but if the answer is no then the EV3 will adjust itself one tenth of a wheel turn. If it still doesn’t see it will do it again and so on. The flaw in this program is that the robot is not facing straight after the slight adjustment but facing a bit to the side. It keeps on going but after a while it veers of to the side and the program can only turn right not left so the robot is stuck. My partner and I still can’t work out how to make it turn right when it needs to and left when it needs to!

So far we have made it go zigzag, when we tried it out on the course it still didn’t work and went off the line and didn’t go back. The challenge was to get your robot through the course( without going off the line) the quickest, at the end was a green patch and then to push a person (on the green stuff) away and to safety.¬†Of course that is for the people whose program works! So we adjusted our program and it still didn’t work, here is a picture of¬† it¬†below.

What¬†we¬†made¬†it¬†do¬†was¬†to¬†just¬†zigzag¬†but it didn’t move at all so, back to the drawing board for us! So far we have made¬†over eight¬†programs and guess what, they don’t work. The furthest we have got is four boards but that was with us putting the robot back to the right place and we’re not meant to touch it! I would put in all the¬†programs we have made but there is abit too many. The challenge for the people that aren’t doing Robo cup is to make your robot follow a circle, our first program worked on the circle and went at about 1 km an hour and¬†took a few minutes to complete!! I really hope that we get the program and complete the course but we haven’t yet!

We found out that we could put two colour sensors on, at first I thought it would make it easier but no it made it harder. First we had to put together a normal program and add  switch bricks in switch bricks. This is what a switch brick looks like.

A switch brick can be asked the question ( the tick is yes and the cross is no ) you can put other bricks in the switch brick ( including switch bricks ). The program we made had four switch bricks, one repeat brick and loads of move bricks. Here is a picture of it below.

The day of ROBO CUP

On Friday 15/6/18 the Robo cup teams all went to Christion College to compete, when we got there it was raining and we had to protect our robots from “the rain”.¬†Once we had arrived we set up and got to work. We tried our robot out on the course and one of the colour sensor’s had turned off. We changed the program but no success. I was freaking out and so was the rest of our team. For a whole hour is didn’t work, suddenly we realised it was our turn to put our robot on the course. I remembered a program that we had decided not to use but we had to use it. We put the program into the robot and didn’t have time to test it. the timer started and we pressed the program and the ev3 was off. It worked!! we where so, so, so excited. Sadly the ultrasonic bit didn’t work but the line following worked amazingly!¬†We tweaked¬†the¬†program a bit to try to make it work.

The next round the course was harder but the robot got through it ( the ultra sonic didn’t work again ) We tried to improve it again but the ultrasonic refused to work. We tested out the dodgy¬†program but nothing had changed so we decided not to waste our time on it. In the third round they added the bridge, we were worried because on¬†the bridge the robot stuffed up. As we had guessed the robot¬†went of the line at the bridge and we had to put it back¬†on the course.¬†You get ten points every board you cross and lose ten points if the robot strays of the board or you touch it.¬†We were trying to adjust it so it worked on the bridge but if we did it messed up the whole program! The fourth round was practically the same but¬†the ultrasonic hadn’t worked yet so we decided to focus on that. We tried lots of things and the black team helped us with it, but no use it didn’t work!

The fifth round was our worst run yet! the ev3 kept on missing the line and messing up! The program was the same but the result was different!

Finally they announced who had won, the RED team came third, the PINK team came second and the BLACK team came first! they were all from Geelong college!! yay!!


 

I learnt from this experience that you have to be logic and patient to get somewhere and that winning doesn’t matter! I would love to do it again and in year six to compete in the dancing robot competition!

Arduino

This term, for three weeks, 5c are doing Arduino. So far it is really fun!

Every Thursday and Friday we work in groups of three and do experiments like the ones in the video. The mechanics of Arduino are used to help operate every-day things like censors and lights. The last project we did, did not work, we had 6 lights and they were meant to flash one at a time and keep on doing it. Sadly all ours did was look like a bunch of lights, wirers and a few bits and bobs, which it was!!

Other than that unsuccessful project all our others worked perfectly and the lights flashed or just stayed on. The first project in the video above is where we used alligator clips to carry the energy from the battery through to the resister {which protects the LED from blowing}and to the LED and the LED turns on! The second project we did was when the breadboard came in. The breadboard is what lets the energy travel through to whatever is put in the breadboard, things like resisters, LED lights and jumper wires can all be put in the breadboard. Then power will run through it, but for it to work you have to plug it in to the computer. After that we had to get Arduino app on our computer and then hopefully the light would turn on and blink.

What I learnt from Arduino was that in building and testing¬†circuits you need to be so precise and everything has to be in the right hole [ or plug ] or it doesn’t work!! In the last project I did as I said before it didn’t work and my group hasn’t worked it out yet!

I really enjoyed Arduino and making all the awesome experiments it had to offer!!

Lego Wedo Project

On our first design lesson we were using Lego wedo boxes ,I was so excited for I absolutely love Lego. We first started making models that the program provided and then we started exploring by adding on to one of the models. We paired up with someone and my partner was Lottie. After some brainstorming we came up with the idea to make a caravan, but we had to work out how to connect two other wheels to the existing two wheeled design. In the end we did it.

First we connected a long lego piece with holes in it. We put a long skinny piece through the end hole and stuck a wheel on it. Then we put together¬† some programing and got the¬† wheels moving! After that we put another wheel on and it still worked! Then we started making the caravan top which was awesome and then we stuck the two bits together and started the motor successfully (yay). We did a few test runs¬† and the top only fell of a few times! But we had to break it to do another one ,this time we made the world’s most dangerous ride (certain death!!!). Each time it spun, a few pieces fell off and so did the Lego people. How we made it was we used the motor to spin and attached a long red Lego piece and made seats for Lego people to sit on. And it worked and ,yes still certain death!!

Then to show our learning we went through a few projects. The first one was dancing birds and we had to make Lego birds spin. I found it quite hard for the first time we made it we did it wrong so we had to reassemble it and find our mistake which was a wrong block so we fixed it and our birds danced. We programed them to boogie, one¬† turned side to side while the other one did 360’s. I realised later that the reason of one bird doing one thing and the other bird doing another thing was that two pieces had a bad connection which was¬† the two blocks that held up the dancing birds.

Lottie and I had time to do another project which was ‘aeroplane rescue’. The challenge was to make the propeller spin faster or slower as the aeroplane went higher or lower.¬† Lottie and I first took turns at building the body of the plane, then we put together the programing. Ours¬† was build right this time which was great. We tested the plane and the propeller worked well (though I couldn’t tell ). I really enjoyed making this for it was so awesome and worked ( which was surprising )quite well.

Throughout this project I really enjoyed it and I would love to do it again. What I learn from this is that you have to always look closer and be open to ideas!

 

how can we create a good tomorrow?

I used to think that the mulberry tree/bush grew from a seed but now I know that it actually grew from another mulberry branch!

I  used to think that potatoes could grow close to each other but now I know that they have to be about two hands apart

I used to think that cockatiels lived near coastline but now I know that they  live inland

I used to think that cockatiels eat meat[not from bugs]but now I know they don’t

I used to think that pied currawongs didn’t¬† live around here but now I know the do live here

year 4 camp reflection

on Wednesday  we hopped on the bus to go to year 4 camp which took 2 and a half hours! when we got there we found out our cabin groups in my cabin was Bronte, Amy, Ellie, me and Hannah B. After that we found out our activity groups. My first activity was zip lining it was so fun we all put on helmets  and harnesses. We all raced each other I won 3 times. Next we went to archery I got two  bullseyes. I loved archery. after doing single archery we went into teams my team won once. After archery my group went to the leap of faith. I did it twice. On my first try I climbed up slowly and was terrified but on the second try I loved it. I really wanted to go again but then my group had to go for  after noon tea. Which was fruit and cookies.

After that we went to the commando course which was so fun we split in two groups. my group won first it was girls versus boys ,girls won of course. Sadly the next race was mixed and my group lost. once we had finished that we went to the high swing!!!!!! I was so so scared  but I still went to the top. for dinner we had chicken schnitzel and chips it was so good. once we had finished dinner we watched the lorax. after that we went to bed but the cabin next to us was so loud, luckily we got to sleep.

the next day we had breakfast and hopped one the bus to go to Yellingbo. we went on a walk and learnt about helmeted honeyeater which is endangered. we even got to see the helmeted honey eater! after that we went to puffing billy which was so fun, we were on it for an hour. once we had got to the bus we went to dandyyong rangers national park. I had a sulfer crested cockatoo on my leg! once we had lunch we went one a walk. then we got back on the bus and went back to camp. that night we had lasagnes and watched yet another movie we were all so tired and went to bed straight away.

the next day we all went to Healesville sanctuary there we saw the platypus show which taught us not to use balloons. then we went to the bird show I especially Kevin the Corella he talked! I loved camp but I was so tired and I missed my parents. I loved camp!!!!

 

 

 

 

 

 

Mt Rothwell refection

On Thursday the year fours went to the Mt Rothwell Biodiversity Interpretation Centre. We got there at 12:20. First we went to the main area, dropped our bags and admired the Dingos [we did other things that shall not be mentioned]

we participated in activities as thanks to Mt Rothwell. These are the activities:

  • brush-tailed rock wallaby watching
  • weeding cape weed so wallaby grass could grow [wallaby’s eat the grass]
  • tracks and scats[poo]we went looking for droppings so we could see what animals were in the area
  • art with Sue Anderson
  • night walk were we saw lot of nocturnal animals

reflection:

tracks and scats. I found it fun to find droppings and burrows even though it was a bit distugusting. some boys found a massive poo. they grabbed a stick and let the sloppy green insides spill out. We found a dropping and checked the insides they where all fibrey that told us that the animal was a herbivore.

art. we met Sue Anderson and each got a piece of paper, a pencil and charcoal. Once we had wrote what we had heard we gave the paper to the person next to us and kept drawing until we had done it about 7 times we got our own piece of paper and painted what we saw that we liked.

wallaby watching.¬†we had to be really quiet[we weren’t but we had to if we wanted to see wallaby’s]there where to different enclosures one for the Easton wallaby’s and the other for the southern wallaby’s. ¬†the southern wallaby’s only had 20 in the enclosure! In the Easton’s enclosure they all came to check us out they were beautiful!

cape weed weeding. in the Easton’s home the were lots of¬†cape weed we got the job of¬†¬†pulling some of them out¬†in that time I lost my voice but I still did lots of weeding.

night walk. in the night walk we saw lots of bettongs, Easton barred bandicoots and a spotted quoll! I loved walking in nature we saw an owl and much more.

 

Mt Rothwell was awesome I saw two¬†Easton brush-tailed wallaby’s! I want to go back.

 

Dog Rocks Reflection‚ėĮūüéć

In week 2 of this term we went to Dog Rocks with our buddies for a Bushkinder excursion.  When we got  to Dog Rocks the first thing I noticed was that on one side of the road was covered in bush and the other side in farmland. On the farmland side there was a Wedgetail Eagle flying with two chicks.

We went on a walk and found a massive tree and decided to build a cubby with our buddies. Once we had built the cubby Mitch, Mackenzie and¬†I tried to think of a¬†password we thought of “can I please come in” but that wasn’t that good, Mitch suggested “ducksithe”I replied ”ducks what?”so that was the password. nobody could guess the password but¬†Mackenzie and I told everyone who wanted to come in.

I really enjoyed the walk and building the cubby. When we were walking we found a rock with an imprint of a massive paw and we decided that the rock had inspired the name of dog rocks. I loved sitting on the rocks by the Barwon River and drawing it. I found this relaxing and I love climbing.

I really want to go back I loved it.
