Sharing & Reflecting on Learning

Electronics

October17

Today we started a new program called “ELECTRONICS”. We started of with five questions to answer. This shows what I have learnt and researched about electricity.

Sense we already know a lot about electricity (because research we did) we were set a new of drawing a circuit, showing the parts of the circuit, showing the purposes of the parts, and writing down what would make the circuit complicated (more difficult). I learnt that a circuit isn’t look very complicated but can be over thought.

Today we were challenged to make our own circuit using what we had learnt. We made many different ways to make the light bulb turn on but this was my favourite.

We then found some propellers and made them spin using the same contraption but using the propeller instead of a light bulb.

Here are the videos we took of everything we made today.

Don’t have video yet

 

Here is more information we found today

The question here is where can you or maybe find a light bulb. The other question was what parts are in a light bulb.

Scratch

Dance party

Today in design we started a new project, Scratch. Scratch is a web sight were you program and make games and story’s and so can much more, but first you need a accounts so you can share your projects with other people all over the world, (my name is lachyness so you can search it up and play things I’ve made).

Debug it

Today in scratch we had to search up debug it and debug 5 projects. Every project had a different problem for example, the first one the other sprite wouldn’t dance and another project the cat was flipping out.

About Me

Today we were set a challenge to make a project that shares things about me. we could share as many things about us as you want. The rules were you had to make it interactive meaning the person playing could do something. This is what I created: about me movie-1r1x5w9

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

May23

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

Mars Rover Challenge

Today I started the Mars rover challenge. It’s about space and you have to do different jobs to help the space station. There is one Mars Rover Challenge that you can do at first but as you go on you’ll need to attach attachments. I focused on building the attachment for this lesson and this is what it looked like.

Black Lines

This term in design we had new challenges. The first one was to start a robot on a white sheet of paper and make it move onto a black line and follow that till the end of the sheet. Black line movie-1gkotlh

Black circle

Black line movie-1gkv4ng 

Challenge mat

Today me and my friend started the challenge mat, you had to make the robot follow a black line that went left and right using the colour sensor. this is what it looks like. We started by turning the speed down because if it is to fast it will fall of the mat which means the program doesn’t work. We decided that when it doesn’t see black it should turn hard to the left, so we made the turn 100 because that’s the highest it can go.

Then when it sensed black we had it turn 50, but it turned to much so we started to change it a little each time until we got to 36. It almost completed the first square but didn’t work but we kept on trying 40 but didn’t work so we had to pack up, but after school my friend tried it again and it completed the challenge mat but he didn’t take a video so we will have to take on next time.

These is a videos about what happened most of the time: squiggly line work and not-17wwewf

Black Line Touch Sensor

Today we had to make a program like the first black line we did. it was the some but when you pressed down the touch sensor the robot stops. First of we had the program correct but for some reason the robot wasn’t moving when we pressed the program and just stayed in the one spot . This is what happened

black line touch

So we asked our teacher and he told us to delete and download it back onto the robot and it worked

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.
