Today year 5 was given the task to make a small Rube Goldberg Machine. What is a Rube Goldberg machine? A Rube Goldberg Machine is a chain reaction of simple machines which is complicated to do something simple. We had to put paper in the bin. We were split into groups and had to plan, design and build a complicated Machine. My group had some ideas like a bucket on a pulley or some dominoes. We didn’t finish in the time limit but we had 2 simple machines. They were an inclined plane and a pulley. The marble went from a ramp to a pulley and then hit the paper into the bin. I learnt that an incline plane, a pulley, a lever and a fulcrum is a simple machine and I learnt that a Rube Goldberg machine often never works on the first time and can get really frustrating.
Today the first of May, 5c had to make some pulleys to lift some marbles which will help us to put in our Rube Goldberg machines. We where put into partners and was given the challenge to build a pulley and it had to lift 5 marbles. What is a pulley? A pulley is a simple machine lice a inclined slope or a lever. it is like a winch and is used to lift thing that are too heavy for humans. Here is a image of the pulley we made.
It is made of string a thread ,metal and a yogurt tubs or aplastic cup.
I learnt that a pulley is in a lot of everyday things like a blind or a flag pole. it was fun creating pulleys and seeing witch one of the three types of pulleys most easily lifted the 5 marbles. we only did the single and the double and didn’t have time to finish the quad pulley. It was a great learning experience and I thing it will greatly help us in our rube Goldberg Machines.
Today the 2nd of may 5c did another mini activity to help our Rube Goldberg machines. Today we where using Lego to build a chain reaction of simple machines like inclined plane and lever. we where in groups of 3 and had our own part separated throughout the class. Our group where given the task to build the Zigzag part of the Rube Goldberg Machine. Here is a link to a Times laps of us building the Zigzag part.
I learnt that Lego could be made into a awesome Rube Goldberg machine. It was a awesome time building the lego to help our knowledge in Rube Goldberg machines.
Today year 5 did another simple machines activity this time it was K’nex and we got a book and had to pick what to build. My group was going to build a conveyer belt. It looked hard and it was but once we finished we where really happy. it was really fun and we had some great ideas to take into our Rube Goldberg projects. I was proud that we finished and was raring put some ideas into our Rube Goldberg machines.
Here is a image of our K’neks conveyer belt :
It was awesome and I learnt a lot that you can do with K’nex and that they can be great to use in Rube Goldberg machines.
Here is a time laps of us building:

Today we had to join our three simple machines together to build a Rube Goldberg machine. we put our Lego Zigzag at the start because we thought that it would be better to start high to gain more momentum to go into the machine. we noticed that we couldn’t use the conveyer because it didn’t work by its self and we needed something that would walk by it’s self. We changed it into a dump truck so we could use the front to hit something and the wheels will help it roll. we thought that it could start at the Lego Zigzag into the dump truck which bumps into a marble which then dropped into a pulley which lifts a marble and the marble rolls over the finish line. We didn’t finish but we only needed to build the pulley. it was great to try joining our simple machines.
This session we started designing our Rube Goldberg machines. Our groups aim is to put the marble away into a box. Our three simple machines are a pulley, wheel and axel and inclined plain. We explained what all the parts we need and why we needed them and also where it goes and what it does. We also designed what it will hopefully look like the finished product. The explanation is what it will do. The explanation is We push the wheel and axel down a tube and it hits 3 dominoes which hits a marble into a pulley which comes up to hit 3 more dominoes which hits another marble into a box.
Today my group started building our Rube Goldberg machine. It was fun and exiting to start building our Rube Goldberg machine and the first thing we built was the inclined plane. We use thesauruses and had a cardboard roll we cut in half to use as an inclined plane. We also built the wheel and axel to roll down the inclined plane which hit some dominoes into a golf ball.
Today the 29th of May We continued on with our Rube Goldberg machine. We built the pulley with tin cans and string. We Also got the rest of the dominoes. We placed our inclined plane then we placed the pulley between the two tables and made it so when the golf ball in the pulley it will move and set dominoes.
Today we had to move because the tables we where using where used for something else so we moved tables but didn’t have to change our machine. We sat the 4 dominoes from the pulley on the pipe to the come around and go into the box so when the golf ball goes into the pulley and the pipe moves across a bit and hits the dominoes. Here is a link to a video of our Rube Goldberg machine working:
The next thing we hope we are going to do is finish our designs.
Today was the FINAL day of Rube Goldberg and we had to finalise our design and make a final video about our whole project. First I finished the design which I redid to fix it to the actual build. Then it was onto our final video. We put lots of photos, videos, captions and effort into the video. Here is a link to our final video:

I learnt a lot from this unit like what simple machines are, what Rube Goldberg Machines are, who is Rube Goldberg and lots more. Here is a link to who Rube Goldberg is :

Once we were finished our machine we had to show it to our parents and to a year 4 class. I loved the Rube Goldberg Machines unit and learnt a lot which will help me at lots of things like building and forces.
