My Rube Goldberg is finally done! I finished the machine part- which meant distorting a really cool idea because it didn’t work- and finished the video which was really hard too because I did my Rube Goldberg with my twin and twins fight a lot. The whole experience was frustrating and also really exciting and fun to try and figure out what to do for each part. In the end, we ended up with THREE pulleys, and I thought that that one was going to e the simple machine that we had the least!
The biggest challenge that we faced was the end. for starters, it was really hard to come up with an idea. when we were finally able to come up with our idea, it didn’t work that well. we then had to come up with another idea which wasn’t as cool. then we had a problem with that idea because the ball that we used didn’t fall into a cup. we then had to change the design a little more to make it work. one the sunny side, because we worked so hard on making the end work so well, we only had 10 tries.
we know have 3 pulleys, a lot of inclined planes, and 1 wheel and axel. I think w did a pretty good job of adding simple machines in the right places and were where necessary. the hardest simple machine that we tried to fit in was the lever. I know that might sound crazy to some people but it is true. actually, our last part was the lever and it didn’t work so we had t get rid of it. we changed it to a pully, which worked really well.
our task was giving our dog charlie a treat. finding a way to do that was challenging but after some brainstorming and a few mess-ups, we had a great idea. it was to lift a cup with a treat under it, revealing the treat. our dog was really annoyed when he was waiting for his treat for a long time. he caused a lot of trouble when we wanted him to stay in one place because he is still sort of a puppy so he is not that patient.
overall I am very proud of this project and how we made it. we did a good job with stuff like coming up with ideas and tried to include the other’s ideas somewhere in the machine. I feel like a thing that we could improve on is not fighting over the silliest of things when we were doing the project like whether or not it would work or if we had to add an extra thing. I would like to thank my mom and dad for helping me with filming and helping me to not get really frustrated when something didn’t work and to instead make it better.
