This week our task was to create a Rube Goldberg machine which is a difficult series of events to complete a simple task and our task was to put a piece of rubbish in the bin. In this machine we had to use three simple machines and ours where a ramp, pulley and a lever.
The reason we have a thicker pole on a thinner pole is because then it will spin and make the pulley work.
There is a piece of paper scrunch up in the ramp which is also made out of paper and so when the pole spins it makes the rubbish role down the ramp and into the bin. When we failed most times it was because the ball didn’t go in the bucket/pulley or the paper didn’t go in the bin and it would go off the edge off the ramp.
After completing this project I realised how hard this is going to be but its not going to work if we cant make mistakes.
This session was a mini session so we were not completing a Rube Goldberg machine we where making things the we could use in our machine and be helpful and this session we where working with Lego. This kind of like a rube Goldberg machine because it is a long series of events but it does not complete a simple task. This was in parts so we split up into groups and each built a part of the machine we built the part with the ramps.
This was very difficult and we did achive to make the structure but when we tested it out it would always fail this was a challenge and we don’t know if it was the machine or we just didn’t know how to work it.
This session was also a mini session and this session was super helpful and I will definitely be using this for my rube Goldberg machine and this mini session we where creating knex structures.
This session we where finishing our simple machines, structures and Lego machines.
This session I couldn’t wait to get started because we finally are doing the rube Goldberg machines. Starting my design was quite hard without an idea so my group brainstormed what our machine could do or complete. We finally decided on playing music from a laptop. From all the help from the mini sessions and practise machine, thinking of an idea of how this is to work was not to much of a problem. This machine is quite similar to my practice machine but obviously different because its a different task and if I did the same I wouldn’t be learning anything.
Session 6 & 7-
I bet this was the part we were all waiting for… BUILDING! And from the very first moment we started to build I know challenges weren’t my enemy, I will fight the challenges and obstacles I will do what ever it takes to make this an amazing experience.
We had to include 3 or more simple machines so we chose an incline plane, lever and also a pulley.
An incline plane is basically just a technical word for ramp and for this we will be using a clear plastic tube and supported by the pulley.
I decided with some knowledge of pulleys from mini session and practice machine maybe we could include one of those methods in our rube Goldberg machine.
“DONT LIMIT YOUR CHALLENGES
CHALLENGE YOUR LIMITS”
This session we continued to build hard work is definitely something that we faced. This session we were focusing on our pulley we tried the way like I did in he practice machines, I don’t know what was different but for some reason the pulley wasn’t turning to well, I was thinking it was the thicker pole on top because it wasn’t actually to thick so next session my group will definitely trying to make this pulley turn better.
My group hope to achieve next session the pulley to work and spin better but also try to add our incline plane.
WE DONT GROW WHEN THINGS ARE EASY, WE GROW WHEN WE FACE CHALLENGES
as we hoped this session we fixed our pulley we did this by adding a bigger cardboard pole on top, we also added tape around the string so it wouldn’t slide and instead of the string moving it would be the pole.
Yes you might be wondering why would you would put tin cans on the chair, well the reason is because we where originally going to change our pulley and use them instead so that is also why we have string attached. Soon realising that why come so far but then just change it so instead we are using it to stabilise our pulley.
Today the part that took the most attempts was the ramp made out of rulers and I think this is because there is a jump between the pulley and the ramp so it has to be in the right spot for it to work.
So this little colourful block of lego is to hold a little marble, it is set off by the thicker pole on the pulley turning.
Next session we hope to add a clear tube for the marble to run through.
IF YOU CAN DREAM IT YOU CAN DO IT – Walt Disney
This session we did add the clear tube this took a long time to set up because the weight of the tube pulled down the pole and the marble would run straight through the tube without even moving the pulley. If the marble that went through just went straight to the spacebar it wouldn’t be to much of a entertaining machine and we wouldn’t learn from that.
We are hoping to make the marble hit something like dominoes or a ball we are not to sure yet. but doing this means we will have to re-design.
