are starting rube Goldberg machines, rube Goldberg machines are machines that are very complex but to do simple things like open a can or turn on a light.
Rube Goldberg challenge
Today we were put to the test to make a rube Goldberg machine in 2 hours. I found this really hard because we didn’t have the best idea to put a piece of paper in the rubbish bin, and i was also too worried about getting it finished in time, and the last problem was that we didn’t even get our design finished properly! other than all of them it was quite fun.
Session 1 (simple machines)
Today we started to get a proper idea of what simple machines we can use in our rube Goldberg machines. The aim was to make a simple machine out of knex. We chose our groups and started building. My group decided to make old fashion scales, it was quite a challenge because some of the knex weren’t fitting in the right place. simple machines-1avbked
For our second session on simple machines we focused on pullies. First we started of by making a simple pullie with 1 of the things you will see in the photo ( I don’t know what they are called). Then we made a double one that was stronger than the first one. and then we made one that had four of them. The first were easier than I thought but the last one was the biggest challenge. I found the last one hard because it was really hard to get the string in the right position.
Today me made Lego machines. We got to make a triggered hammer. The biggest challenge of all was finding the pieces, in fact i probably spent half of the session trying to find the pieces! This wasn’t very challenging for me because you don’t learn by trying to find pieces of Lego, but putting it together was easy. I didn’t get to finish it off the next day because I was at cross country.
this video is 16 times its own speed and it still looks like it would take a long time to find the pieces! (it originally went for 30 minuets)
This was the best activity to do to finish simple machines. We gathered every thing we made and made one whole big simple machine. the biggest challenge was to make the pulley work because the marble keep on missing the tub. On our first official attempt we got it on film and strait away, but the we had to make the scales work as scales not a platform. I will definitely try and use these machines in the real rube Goldberg project.
Today was my first rube Goldberg lesson because i was sick the other day, but luckily i got my plan finished in time. Our goal is to poor a cup of water. After we finished our plan we got to start building, we got told that if we build the simple machines separate all we need to do is test them and then find a way to join after, not spending half the time on figuring out a way to join it before you have even tested it or built it. My group didn’t seem to be cooperating with me because they were getting distracted and then made it much harder. We got to make a pulley but it doesn’t really look right so we might have to re make it.
Today my group got a lot finished. we redesigned some part and fixed them. we got rid of the dominoes and replaced it with a toy train track. we changed the pullie after i wrecked because it wasn’t working, then we came up with a much more smarter idea. it was to get rid of the plat form that was holding the pullie and then attach the pullie to the end of the tunnel. all we need to do next is make the pulley string shorter.
Today it was a shorter session . i found it really annoying because my group was calling me the passenger and they just keep bringing stuff up that he does much more than me. We didn’t get to shorten the pulley string but all we really is make the starting point higher. I don’t think we will get it finished in time.
Today my group was a bit better. it started off like yesterday but after an hour better. The bad thing was when i built knex tower, i needed this one piece but it had a little ball in it and i needed to get it out so i asked Mr Colbert and he went to all the effort to get it out but as soon as i got back to my group they have already made a different tower, and mr Colbert went to all that work for nothing.
this was the ball
today we got a lot finished considering we only had 2 people in our group. this is our last week on rube Goldberg so i said to my self we better get a move on, and that’s exactly what we did. I changed my design so it matched the machine and we got the spinning object and got that into place, now all we need to do is get the other plat forms and the water bottle and then connect it together and then test and test and test.
today we didn’t get het much finished. This was really bad because we should have been finishing off the rest of our machine. all we really did was test and redesign then some times break it accidently. We had to do a video but we forgot to start it today so we have a lot of pressure on us for tomorrow.
Session 8 (last session)
today you wouldn’t believe how much we got done today in 2 hours. today we changed our design again and changed the purpose of the machine! we got rid of the pullie and changed it to another tube, then what our machines purpose was to play a game, the game is actually really addictive when it works! We got the videos for the videos finished and all we need to do now is film ourselves for the video saying how we think the group went and if our machine was good or not.
To be honest i didn’t think we were going to get this far with our rube Goldberg machines because it just wasn’t working until the last 3 session, we started to under stand how long we had left to finish it and that we could change our design. After all i am really happy with our rube Goldberg machine. The only thing that isn’t that good about our machine is that i think it is WWAAYY too simple, because the only simple machines are inclined planes/tubes and ramps. Thank you teachers for bringing this task into my learning!
