Session 1 – 21/04/2017
Our introduction to Rube Goldberg Machines started today. We were put into groups of three with the aim to put a piece of paper in the bin. But no, you couldn’t just chuck it in with your hand! Each group had to include at least 3 simple machines, like a lever, pulley, and wheel. We had two hours to design and build a Rube Goldberg Machine.
My team had an awesome crack at it, and we came up with mountains of ideas, but most didn’t work. The teacher then said that as long as we had a good idea of what we could do next with our machine, we didn’t have to be finished, or even have a part working yet, but we had to know what we would do if we had a lot more time.
I loved getting the opportunity to work with different people than I would usually, and found it really fun to try and find their main skills. At times I could feel frustration and pressure building up, but then one of my teammates or I would have a brilliant idea, and we would have fun trying different ways to get that to work.
Pulley – 01/05/2017
A pulley is one type of a simple machine, and today we got a set of instructions and boxes of materials to complete our task of making a pulley. We got into pairs, and my partner and I did two of three different Pulleys. We had around an hour to make at least two different Pulleys out of soft wire, string, yoghurt container, scissors and cotton reels. Here is a link to a Time Lapse of our Pulley session.

I learnt the materials that you would base your Pulley on, and I also learnt a stronger Pulley that can hold a lot more weight than a single Pulley and is a lot more stable. I had heaps of fun, and learnt the basics of a Pulley.
The simple machine in a pulley is really a Wheel and Axle.
Chain Reactions – 02/05/2017
For one of our sessions in Rube Goldberg, we did a chain reactions project with Mrs. Watson. We got into partners and got all our materials and started building. Each pair of partners had their own part of a big chain of reactions. My partner and I were assigned to build a board bouncer.

Knex – 03/05/2017
This session in Rube Goldberg we worked with Knex, taught by Mr. Colbert. Here is Movie of my group of three’s progress.
The hardest bit for the building process for me was getting started, but once I got into it a bit more, I had so much fun!
This ties in with our Rube Goldberg Machine project because we could defiantly use Knex in it, and I have become so much more confidant using Lego and Knex.

All 3 Simple Machines Together – 05/05/2017
Today I was had soo much fun joining all three of my projects together. First I got all three of my simple machines ( Pulley, Board Bouncer, Wheel and Axle Rubbish Truck ) and got a partner which I had worked with in one of these activities. My partner wanted to incorporate her Chain Reaction Machine, which is in the picture below.
We then had an awesome idea, and our aim was to make the BOOM! sign pop up. We put all of our sections on the floor, and placed a chair in front of our parts. The only thing you had to do was pull gently on a string. Here is a video of it in action.
Since we had our working Simple Machines task done quite quickly, we were able to choose another 2 or 3 people who were also done to join with. The new Simple Machines we got to add in were:
Now, with 2 more machines to add in and 4 people in total, we decided we needed a more challenging aim. We all agreed on making our new aim to press the space button on a computer to take a photo. We had many attempts, but only a few worked because it was really difficult getting the last domino in the exact right spot to bang onto the space button.
In order to take a photo using the space button, you need to press and then lift. We used the dominoes only to press the space button, but we still needed to lift the domino back up. We were able to use a Carousel two of us had made, and it would turn around by you turning a stick. We used the Carousel by tying string onto the Carousel and joining it to the last Domino, so that when the last Domino hit the space button, we would wait a few seconds and then turn the Carousel stick. By turning the stick, we would drag the domino off the space button, and there-fore taking a photo.
Here is a Video of our machine in action.
I loved the presentation of this activity, how we sort of did rotations and then combined them together. I loved the opportunity to work with different people and find what their skills are.
Session 2 – 15 / 05 / 2017
All the Simple Machines workshops we did were leading up to this… Today, for the first proper session in Rube Goldberg Machines, we started our designs. With an hour up our sleeve we all got a good design started.
We listed our materials, and how we would use them in our machine. We had to have an aim, and ours is to open a book. Each person in the group of three had to have a detailed design before the group got to start getting materials and building. Every Rube Goldberg machine had to have a minimum of three simple machine, but only each different simple machine counted, so you could have 4 incline planes that only counted as 1 simple machine. Your Rube Goldberg machine also had to be easy to set up, and transport. In you design you also had to include a drawing of what you want your machine to look like.
Here is a photo of my not yet completed design.
I have finished most of the writing, but still need to work on my drawing. I have also been labelling the materials on the drawing.
Session 3 – 16 / 05 / 2017
This session we had to have a detailed design finished in fine-liner by the end of the lesson. I have added a little bit more on from yesterday’s work, including a description on what is happening in my drawing.
Session 4 – 18 / 05 / 2017
This Rube Goldberg session we sorted out who was going to bring in what materials. I agreed on bringing the Scissors, a picture book, two thick books, a marble, a golf ball, a cardboard tube, and a storage bag. I also updated my design to remind myself what I needed to bring in.
So the plan for building is to first set up what we have in our designs, but if it doesn’t work then experimenting with the end of the machine, which will succeed out of pure luck.
Session 5 – 19 / 05 / 2017
I was away sick for this session of design.
Session 6 – 30 / 05 / 2017
This Rube Goldberg Design I had a really good go at my first session of building. I was so exited to get cracking! We only had an hour, but I think we used it well. We set up the first 2 parts of our machine; the Inclined Plane, and the Pulley. We didn’t get them to work, we just got them set up and ready to be polished up.
Incline Plane and Pulley
Session 7 – 1 / 06 / 2017
This session we kind of changed things around. We moved the Incline Plane to the ledge, but a little lower than the Pulley top. We made sure to keep referring back to the Design, in our Design books, to retain what we had originally planned.
We moved the Incline Plane from the table to the heater so that we would be able to work on four levels; the ledge, the heater, the table and the floor. We also got it working! Hopefully in the next few sessions we will add something that tips the marble out once it reaches the top of the Pulley. We will then continue our machine on the table, and then onto the floor. To make it more exiting, we are thinking of adding some bend and turns, or maybe an uphill, to give our machine more OMPH!
What I learnt from this session is that you will most likely get your machine to work 1 out of 10 times, and you have to be happy about the time that it did work, and think of what you might have changed to make it work.
Session 8 – 2 / 06 / 2017
This session, we finally got our machine to work! Or, at least the Inclined Plane and the Pulley.
We moved the Pulley top over a bit, so that we could fit a ruler for the marble to run down. In one of the cups we also cut a small hole, big enough for a small marble to fit in and out of.
We did this, and also tilted the cup slightly so that when the Pulley springs into action, when the cup that started at the bottom reaches the top, it will be knocked by the ruler and the marble will tip out of the small hole in the cup, falling to the ground where there will be a half cut pipe.
The marble will run along the half cut pipe, where in the next few sessions we will work out adding some bends, and then achieving our goal, to turn a page of a book.
I think that in every failure we had, we improved our knowledge just a little bit. Even if it was to always start the Pulley a little to the left, or whatever it was. I hope that in the future, we could improve by adding more of our machine into life from our designs, and also succeeding in less than 10 tries.
Fail / fantastic achievement in life!
Session 9 – 13 / 06 / 2017
This session both of my other group members were away, but I tried my best to do the most I could in the hour I had. My main goal for this lesson was to 1: finish building and 2: get it working when finished. I tried changing lots of different things but it always just NEARLY worked… in the end I decided to maybe change what would turn the page, which is our aim. Here is a video of one of the ones that didn’t work.
In the end I got the machine finished, but it always NEARLY worked.
In the next lesson I hope to perhaps change the way that we turn the page, and then also updating my design to what I might do. Tonight I will think over some other simple machines that we could use to turn the page over instead of a lever.
Session 10 – 15 / 06 / 2017
I thought of, and listed down all the simple machines I could think of; Inclined Plane, Lever, Pulley, Screw, Wedge, and Wheel and Axle. Then I had an idea!! We could use a Wheel and Axle, and put it inside the book. I quickly found a wooden skewer, and a small cotton reel. When the time ticked around to design, I double checked my idea with my group, just to make sure they were ok. Once we had got the other material we needed, we quickly built my idea. In half an hour, we had gotten it ready for a trial. After a few trials (fails) we made a few adjustments to our second Inclined Plane so that we knew the marble would always roll into the cup of our Pulley.Here is the adjustment.
Next session we will work on getting our machine to work every time, and get our group video completed.
Session 11 – 16 / 06 / 2017
This session we got our machine working every time, and we worked on a video explaining our journey through the Rube Goldberg Machine topic. In each groups video, we had to include in whichever way we want; A video of each group member explaining their learning throughout the journey, a fail and success video of your machine in action, and finally all, or one group members design. You were certainly allowed to include more information on anything about your groups machine.
This was our last session, and I think our focus this session was really good. I had lots of fun show-casing my learning, and it was hilarious seeing the looks on everyone’s faces when our machine finally WORKED.
Here is photo of our final Machine.
Here is our final success video.
