Rube Goldberg Machine
Today in class we started designing/ planning the beginning of our Rube Goldberg Machine, My group work out that the purpose is going to be that it is going to take a photo on a computer of anything we thought it could do this by dropping a marble onto a computer, but only a small marble so it doesn’t brake the computer we are using. We worked out that the materials we are using are going to be….
- Balls (A golf ball and 2 marbles)
- String (for the start to pull)
- Cardboard box (To hold every thing in and to cut for ramps)
- Lego (To make Lego dominoes)
It is going to do this, it stares with a platform that has a piece of string on the bottom of it witch you pull and makes it a ramp witch a marble role down into a funnel and then down a long ramp witch makes a marble hit 3 Lego dominoes our group chose to us Lego dominoes because we thought it would be easier to set up that using small dominos and so it would noke into the next thing harder, we did not get to do the rest and we will do it next lesion.
Our goal next lesion is to finish our design and then label of what it is what it does and what force is at use. We hope we can also start building.
Today or grope finished of our plan these are the materials we added…
- Yogurt cup #2 (For pulley)
- peace of paper (To fall in the bin)
- Pool noddle (Instead of ramp)
And this is what we added, so after hitting the Lego dominoes it knocked into a golf ball witch rolled into a yogurt cup witch was a pulley when the golf ball rolled into the yogurt cup it became uneven making the side with the golf ball in it fall down to the ground were the computer was waiting and the cup fall onto the photo button, but in steed of stopping there we thought it should have 2 purposes so while the other side was going down and taking a photo it came up with a little peace sticking out of the sided witch hits a ball that knocks a peace of paper into the bin. Materials
That only toke a few minutes to draw so we got to build the first 3 simple machine, we started to build was platform that turns into a ramp and it falling into the funnel followed by the pool noddle first.
The hardest part when we were making it was, making sure it tiped when you pulled the string and didn’t just fall It was also hard to make sure that the marble fall into the funnel and not the ground To fix it we mad the ramp small so that the funnel covered, over the whole/ramp. To bullied it we used…
- Pool Noddle (For ramp so it is different)
- Peace Of Cardboard (For ramp/ platform)
- Marble #1
- String (To pull)
This is what it looked like in the end……
Next we started to build the Lego dominoes witch the marble hits after rolling through the noddle.
We had to make them a few times because, the first time we made it, they were to big and the marble was not powerfullenuf to nock them over we keep on trying different ways until we got 3 skinny ones but we thought 3 Lego dominoes was to many so we changed it to 2 Lego dominos.
This is what it looked like in the end…..
Today in design, we went bake to our Rube Goldberg Machine and realised that we were just focusing on one part of the machine that wasn’t working and it wasn’t going to work. We had to change it and now it goes like this. ok so the beginning is still the same it is just after the marble comes out of the pool noddle instead of knocking into the Lego dominoes first it knocks into a bigger ball that is strong enough to knock over the dominos so the marble comes out of the pool noddle and knocks into a bigger marble witch than hits the Lego dominos that then hits a little marble witch falls through another pool noddle that fall onto a seesaw witch a piece of paper is waiting on one side and the marble falls onto the other a makes it fly into the bin and its done.
At the end we looked at it again and realised that it was just pretty much just started at a high point and finished at the lowest point and a few things happened in-between. So next lesion we are going to change that and change our design to what the Rube Goldberg Machine looked like.
Today my group looked at our Rube Goldberg Machine and tried to see a way to change it from just going straight down and we tried making it go along the table and then get to the end this is what we came up with…..
But we didn’t like it so we changed it bake to our old Machine because we did like that one, we thought we could just make it perfect and work every time. We spent a long time trying and trying to get it to work until it finally worked…
The Finale Lesion
Today was the final lesion and my group was working on making sure it worked 8 out of 10 times and the finale video hear it is….
Over this past term I have learnt a lot, hers a few, Rube Goldberg machine is a complex machine that does a complex task, that simple machines are used everywhere and that I most enjoyed making it, sharing my ideas for it and doing all the small simple machines and I think it defiantly helped when we did the real machine. My favourite was the pulley , If I did again I would make our rube Goldberg machine have more ups because I rube Goldberg machine started at the highest point and finished at the lowest and a few things happened in-between I would also added more detail to my design and I would make it go for a little longer but I think my group did really well and I enjoyed it a lot and would defiantly do it again or do something like it.
Rube Goldberg mine simple machine
Today we had to make a Rube Goldberg machine the goal was to make a complex machine that does a simple task with a series of actions that happen in a domino affect or a Rube Goldberg machine, we had to make it in 2 hours, in a group of 3, The machine could do any thing you wonted, but it had to make a piece of paper fall into a bin.
when we first started my team thought of a whole bunch of different ideas that didn’t really connect, so we had to stop and work out a plan. Our first plan involved 7 different materials or action, they included our wood work car, a few dominoes, a golf ball, a yogurt cup, string, paper and a rubbish bin. It went like this, the wood work car hit the dominos, which hit the ball, that rolled into a cup which slied down a piece of string like a zip line, which hit a piece of paper that falle into the bin. But when we bilt it the zip line didnet work because it would get stuck half way though the zip line because when we cut the yogurt cup it was not perfected and there was little jagered bites that it would get stuck on. After a wile we stoped because we had relised that the zip line was not working and was just taking up time, so we got rid of the zip line and replaced in with a marble that went though a pipe that loped aroned under the table and hit a piece of paper into the bin.

we thought this was going to work better because it was more simple and essayer to build but it still was a challenge because every time the dominoes fell they would either hit the ball to the rong side, miss it or push it slightly but not far enough.

Rube Goldberg 1 lots-qjrlxc
In the end of the two hours our Rube Goldberg machine only worked 1 time but it was lots of fun to build it. Next time we build a Rube Goldberg machine I am going to spend time on each little action/task and go step by step rather than rushing ahead and doing every thing at once. Next time I am going to added more detale to my plan of the Rube Goldberg machine because this time we mad it, it was just a little pitcher with not very much detale, words showing what is happening or using words like gravity, momentum, speed and friction.

If I did it again I would try to spend more time on it and think carefully and I would also go in a group of 2 and do something easier.
I can not wait to do it again.
Rube Goldberg machine Lego.
For this week in design we are going to do small little activates with the teachers, To help use for when we are making our big Rube Goldberg Machine and to help let use know how to make it.Today we made a Lego Rube Goldberg Machine, we got put into groups of 3 and 2 and then made a one of the small simple machines. We got given the pulle it was a tower of Lego.
It was hard because in the pulley there is a paper cup that the ball falls into, to make the weight uneven and the cup fall which mad a Lego block go up and hit a ball, but the ball was to far away and the Lego block wasn’t hitting it, so we had to added a little bit on the end of the paper fore the ball to sit on, but it still didn’t hit the ball, so we kept on trying new ways but didn’t get to finish it, it was also hard because everyone was getting annoyed that the ramp was not working and this mad it hard for us to think of a way to fix it.
Next time we work on it our group is going to try cut out a new ramp and make it a bit longer so the Lego block can hit it.
We were focising on the simple machine in our pulley which was the part in the machine that made the pulley go up and down, this worked by a force could gravity, one side would have something hevyer in it than the other which meant gravity would pull down the side that was heveyer than the other to make the sides uneven and the ather side would come up and nock the ball that was sitting on the ramp which would roll down.
if you can not read this the circle part is the simple machine in our pulley.
I think I would defiantly use this in my Rube Goldberg machine because it is a good why to make a ball movie rather than just letting it roll along the ground, I also think it was fun to build and if I added it in I would put it in a spot were one of the simple machines were going to gone to the next.

If I did it again I would try to help a little more to make it rather than take the photos and I would try something different.

Rube Goldberg connectix
Today we continued to do the week work instead we went with another teach and used connectix. We were allowed to buled any thing in the instruction book that had a simple machine in it, my group chose the scales.
There was not very many problems in the proses of making this but it was hard to connect the knetic together.
conect movie yes-2cyeyn7
Today we went to get our simple machine but it was broken into little pieces so we had to start again but this time it was a lot easier because we new what we were doing and there was an extra person in our group so we all had roles 2 people would build at a time another person would do the videoing and the last person would get the pieces and then we would switch. There wasn’t many problems but every now and agen we would argu about how should be building and how shouldn’t.
The simple machine in this scale is acryle not the hole thing it is only the part in the part that makes the scale move from side to side it moves because if you put a heavier thing in one side lake a few Lego blocks than it would make the scale uneven there for the side with the thing on it would fall down lifting the other side up into the air then using this you can measure what is heavier than another thing.
If it is not clear is says that the circled part is the simple machine.
If I added this into my Rube Goldberg machine it would go some were in the middle to connect one simple machine to the other, but I probably wont us it in my Rube Goldberg machine.
if I did it age I would try something harder and I would try to build more than taking the photos for everyone.
Rube Goldberg pulley
Today we continued to do our Rube Goldberg thing to help us to know what to do excepted we mad a pulley. On the Instruction shat there was 3 different ways we could make a pulley and each of them keep on getting harder.
The materials we used were,
seizers, string, yogurt cup, marbles and. The easy parts were putting the wiyer and tiying the string to the wire the hard parts were making the hock for the pulley to hang from and rapping the string around the.
I would defiantly added this to my Rube Goldberg machine any were because .1 it was fun to build but a bit of a challenge .2 it is a very good simple machine to put in and .3 it is a good why to get a ball or what ever across the table or something in a complex way rather than something boring like rolling it across the table

If I did it again I would try to do it from higher up and see if it would work if you used more materials.
