simple machines

 

In this project, I learnt not to over complicate things. After I learnt to simplify things I was able to achieve my challenges more effectively and efficiently . This enabled me to proceed and dedicate more time and effort to making my complex machine more complex.

 

The lever

The lever is an invention that helps lift heavier things. The lever has a stand{fulcrum} and two poles. Behind the stand are two shorter poles they act as the lever . A fulcrum is the stand that the lever relies on.

wheel and axel


the wheel and axel is a straight forward invention because all it is a rod in the middle of two wheels. The axel is used to turn the wheels and hold the wheels in one place.

 

 

The wedge


The wedge is made of two inclined planes. Unlike the inclined plane the wedge is used to push thing apart. The wedge is used in inventions like blade of the axe. In my model of the wedge I built a triangle with the bottom connect bigger than the other two tis made the triangle edges sharper.

 

 

Inclined plane


An inclined plane is a slope or ramp that makes it easier to lift something. On my model of the inclined I have a stand with three rods coming off it. The stand is to make the structure inclined otherwise it would not help anything let alone lift things. The rods are to make the model look like a ramp.

the pulley

the pulley is an invention that does all sorts of things like helps pull buckets up like in a well. A pulley contains a wheel, so the rope goes up and down and a piece of rope. The rope is there because it makes you be able to control the speed of the bucket for example.

the screw


a screw is an inclined plane wrapped into a spiral. The screw is used to open bottles and pull corks out of bottles. In my model of the screw I grabbed a long rod and started putting red join pieces to the rod than a put small green connects in the red joining pieces.

 

my complex machine 

my complex machine is a splitting wedge. the splitting wedge is used to cut stumps of trees in half for fire wood. the way you split the wood is you put the wedge on the wood and hit it with a sledge hammer. the splitting wedge is used all over the world. the simple machine in this machine is a wedge. this took me about thirty minutes. there were a few difficulties in making the splitting wedge like figuring out how to get the connects into the holders.

 

 

 

Lego wedo ferries wheel

Because I had made my complex machine quickly I had the opportunity to use the updated version of Lego wedo. I took the opportunity to explore the new version of wedo. we decided to make a working ferries wheel. it took about one hour and thirty minutes. there were not to many difficulties apart from when I just finished the first carriage and I was feeling good about myself  then I realised I had to make three more carriages but luckily I new the proses of by hart in the end. this was a very fun way to learn to construct new things.

wedo goal keeper

today I made an other wedo construction. I decided to make a moving soccer goal keeper. this was not very hard at all and there were no difficulties and it only took thirty minutes. the simple machine in the goal keeper is a pulley. the pulley controls the goal keepers movements. the pulley is the most Important part of the goal keeper because without it the goal keeper would not move.

micro worlds

introduction 

today we started our unit on micro world. micro world is an app that teaches you to make shapes. you make shapes using special commands and when you do these special commands a little turtle moves you can make the turtle go forward, backward, turn left how many degrease you like, turn right how many degrease you like, draw with commands and so much more.

first challenge 

can you make a symmetrical trapezium?

making a symmetrical trapezium wasn’t very hard because I played with micro worlds last year so I had a head start. I found out that every individual  angles should add up to 180 degrease so it was easy after that to figure out the angles. below is my trapezium at the top there are tow obtuse angles at the bottom there are two acute angles.

this is my program for the trapezium 

second challenge 

can you make a parallelogram?

making a parallelogram was not very hard because in math we measured the angles of parallelogram so I had a bit of a head start. I found out that if you turned my parallelogram on it’s side it looks like an rhombus.

this is my program for my parallelogram 

 

third challenge 

can you make a rhombus?

this was the hardest challenge yet it took a lot of trial and fail but every time I was thinking about the internal angle as well as the external angle. because I know every angle should add up to 180 degrease I could estimate the internal angle than get a rough Idea of the external angle than from there I could guess the angles.

this is my program for my rhombus  

forth challenge 

can you make a kite?

in this challenge we had to make a kite. again this took a lot of trial and fail with the angles. in this challenge I learnt that the kite that I made the top two sides are the same length and the bottom sides are the same. I also noticed that the top sides are a third of the length of the bottom sides.

this is the program I used

this is my kite

 

 

fifth challenge part one 

using x and y to make a square 

today we had to make a square using x and y and quadrants to make a square. this was the hardest challenge yet. this challenge took me about thirty minutes. in this challenge I learnt that x goes before y and the quadrants are divided into x, -x, y and -y.

this is the program I used

the square 

fifth challenge part two 

can you make a square that’s not in the middle of the screen using x and y?

in this challenge I had to make a square that’s not in the middle of the screen using x and y. this was not very hard and it only took me ten minutes. in this challenge I learnt that if I don’t start I have to add to one number and subtract from the other number.

this is the program I used

this is my square 

fifth challenge part three

can you make four quadrilaterals in four different quadrants? 

in this challenge I had to make four quadrilaterals in four different quadrants. this was the hardest challenge I have ever done. this challenge took me about an hour and it took a lot of thinking and reflecting on what I learnt so it could help me get the challenge done. in this challenge I learnt to use what I have already found out and use that to my advantage.

this is my program for the quads in quadrants challenge

challenge 1 tri led 

 

 

Challenge 2 tri led

 

challenge 3 tri led

 

 

distance censer
In this challenge we had to use a distance censer to make things light up and turn. A distance censer is a piece of technology that censers if the thing it is told to censer is more than whatever you program to in this program we set it to thirty. So if you take the distance censer away thirty centimetres the lights will turn off.

 

Challenge one distance sensor
In challenge one we had to turn a tri-led on while we had this was quite easy because the website showed us the programming, but we still had to find everything. The only problem was that we could not find the distance brick, but it turned out that we had to click an arrow and it dropped a load of different options and as soon as we found that we were done. down the bottom you will find a photo, this is how we programmed the light and the distance censer.

 

Challenge two
In this challenge we had to get a servo motor to spin and a light to turn on all being controlled by the distance censer. The distance censer controls the servo motor and the led by being programmed to be in control of them when they are in a twenty five centimetre radius of the servo motor and the led but when it is not in a twenty five centimetre radius the distance censer is not interested and the servo motor and the led turn off. This took a lot more thinking than the other challenge. It was very difficult to program so many things at once. The main parts to the programming the led bricks, the servo motor bricks and the distance censer bricks.

 

 

 

Footy ground
Mini MCG
In this project we had to pick a project and use an input and an output. we thought it would be cool to make a footy ground. We had the Idea to make light posts and put the led in them like a footy ground. But I wanted to make a game out of it by making a ball and flicking goals, but we decided it would be to easy to get goals. I had the idea of sticking the servo motor to the footy ground and making it turn. Soon we realised that it would not hold the ground. After that we thought that I would be cool to use the vibration motor to make it hard to flick goals. The vibration motor was not strong enough to shake the ground. Then we thought that we could use the turn motor but after we got it all working and turned it on the wires on the led got tangled. Then Mrs Watson came over a suggested that the light should only be on when it’s dark like when they turn the lights on in the AFL. We all thought it was a great idea and we should try it so we went on a hunt for a light censer and we found one. After that we programmed ang got it to light up. Just before we had taken a video of it working the computer glitched and turned off. When we got it back open we found that it was not there because we forgot to save it, so we had to do it again but that time we did it better and finished just on time.
Below you will find the programming code this is a very complex passage of coding to the naked eye but it not that difficult after you know what everything dose. All the purple bricks are the leds
The yellow ones are for controlling everything they sort of organize everything. The green and the blue bricks control the light censer.

Me book reflction

1. How did this activity help you to get to know your classmates?

This project helped me to get to know my class mates in an easy way. It was easy because everyone had to make a book and it was not wired in any way. it was nice to get to know everyone and what their into or their interests. It was good to see if I had the same similar or completely different interests so in the play ground I can help them find people to play with if they need or know what to talk to them about.

 

2. Was it difficult to think of things to draw?

N0 it was not very hard to think of things to draw because I’m a creative person and I sort of got some ideas from other people and put all the ideas together and added somethings  to the design. Some other people on my table were doing similar pages so that made it a little easier.

 

3. Did you discover anything about yourself?

Yes I did learn a lot about myself. I learnt that as much as I love talking I also love listening to other peoples story’s and what they like doing. I like this because not everyone likes footy like me but getting to know my class mates story has got me to realise its not bad not to like all the things I like because that would be boring if everyone was the same it is good to have diversity.
