In school, we are working on such a cool project. It is called Rube Goldberg! It is a complex machine that could do a simple task with you just pressing, or pulling something. My simple task is to plug my laptop. You have to use simple machines in your Rube Goldberg.
In our case, we have to use 3 simple machines or more. There are 6 simple machines: the wedge, pulley, inclined plane, wheel and axle, lever, and screw. The simple machines are very important to our daily life. They help us do simple tasks, that is why they are called simple machines. I used the inclined plane, ( ramp) the wheel and axle ( car), and pulley. I made the pulley by putting a ribbon on the doorknob and tying one end to my shoulder rest and the other side was just hanging so I could pull it and the shoulder rest lifted.
It took a lot of time to plan everything out. First, I had to gather the supplies for my Rube Goldberg and I had to think of some ideas that could work for me. I also had to find a simple task. We had to make a sketch of our project.
I used a lot of supplies for my Rube Goldberg. Some of the supplies I used were : Jenga blocks, books, marbles, and a ,ball. It took a lot of time to think out how I was going to plug the laptop. I think that the sketch part wasn’t that hard, if you planned it out. I have 13 steps in my Rube Goldberg, but I am trying to aim for more. It took a lot of time to plan everything out.
The Rube Goldberg had a lot of difficulties for me. First of all my brother and sister. When I was testing out one part of my project I used one of his toys. And my brother stole his toy out of my Rube Goldberg and hid it so I couldn’t use it. I had to find another supply to replace that one. My sister was very clumsy when she went near my project. EVERY time she was near it she would either knock the books down or the train track. At one point I was out of patience and told her to not come near my Rube Goldberg. Another difficulty was one of the things I was using: the Jenga blocks. I was very frustrated with it. Every time I would put the last block on it would all get knocked down, or my siblings would “accidentally” knock them down. The biggest problem for me was making the marble go down the stairs and make it go down in the marble maze. It took a million tries. It was very exasperating. The dinosaur wind up toy was also very hard. I had to balance a block on its head so it wouldn’t go. Finding the right supplies to make it do what I want was hard too, For example the pulley was really hard to make. I had to think a lot for this.
Even though I had a lot of difficulties I had a lot of success’s too. One of my success in my Rube Goldberg project was the simple machines I used. I made my pulley with a ribbon, violin shoulder rest, and a door knob. When I first made this I didn’t think it was going to work but it did, and when it did I was so happy! Also when I chose that i was going to a wheel and axle I didn’t know how to do it. But then I realized a toy car was basically a wheel and axle. I think that the inclined plane was the easiest simple machine to make.I just had to put books under the art kit so it would be a ramp. Out of the six simple machines my favorites are pulley and inclined plane. After I got the marble to go in the marble maze I was really proud of myself. After this I thought that if I made the marble go in the marble maze than I can figure out a way for the wind up toy to go straight.
I also had a lot of ideas but most of them I didn’t use or I made it a better idea. Before I picked my simple task I had a lot of choices. One of the big ones I really wanted to do was pulling a curtain. It was really hard. It was almost impossible. I was going to pull the curtain by tying a string to it and a remote control car was going to pull it. But the remote control car wasn’t strong enough. While I was doing this I noticed that our curtain was a pulley.
I had a lot of inspirations for my ideas. The biggest inspiration was my house items. Every time I looked around I saw how things I never noticed could be one of the simple machines or that I could use it. I didn’t have to buy anything from the store I could just use the things at home. Another inspiration was the past Rube Goldberg videos. They helped me and inspired me a lot. Mrs. Boyer also helped me a lot.
In conclusion, this project is very fun and I hope we do more of these kinds of projects. At first when I heard that we were going to do this project I thought it was going to be really easy, but when we actually started this I realized that there was more to just building it. You had to sketch it, take a video about it, and it took a lot of tries.
