During design process we had many good ideas, but not all of those ideas worked out when we started building. One example is when we build the pulley (the tower of terror) .When the weight in the bucket was to heavy the dominos could not hold down the string. If the pulley weight was to light it will not make the books (fairytale forest) fall over. We had to try many different things, in the bucket and a ball attached instead of a bucket. We are still not happy with how it is going to we are working on this more this week.
We also had the idea to use fidget spinners and we were thinking maybe 3 of them next to each other but when we tried it wasn’t that easy. This is another thing we will work on this week.
Making the sketch was a sort of easy part, but putting all the steps together and making it work together was really hard. We also wanted it in a theme and it should look nice. That was not easy.
this is the photo of our pulley. As you can see there are no books up yet this photo was taken before that idea came to mind. We also changed the bucket (half a water bottle) to a tennis ball.
This is my 3rd blog post for my rube goldberg project, and I am going to talk about our sketch. When we first started we had some ideas but our final sketch is very different then our first ideas.
In my last post I talked about the design up to the pulley. When we thought light about what would come after that, we sketched a book forest, set off by a see saw and a water part with a unicorn rubber ducky. Making the sketch and making it work in real life are very different. We found out that the see saw part wasn’t really working that well and the books would fall without the sea saw part, as long as the first book was positioned in the right way on the cardboard levy. We didn’t update our sketch as the big ideas did not change but the details did.
At this moment we are going to work at the hardest part where a water bottle will fall over and fill a bucket with water and hopefully the ducky will fall out to set the next step to go. That will be a ball that needs to make the fidget spinners move. I think it will be hard to get the waterfall in the right spot (without getting everything wet) and for the bottle not to drop in the bucket. Getting the ducky out will also be hard. We might need to build a tunnel or something to make it fall in the right spot to set off the next step. Or maybe we need to use a ping pong ball instead, but the name is Donald Duck pond so that would not be good.
We will leave the sketch as it is. We decorated it and it is ready to go to school. And perfect for all our classmates to see.
When we got together on Saturday we both had a few ideas and looked at all the materials and tools in Alexas house that we could use. There was so much too choose from. We started building the “seven dwarfs mine train”, we cut open a long tube (from wrapping paper) and cut it in 3 piece and taped it to the wall, using blue tape. The tubes had a down angle and we tried to let the marble go down. At our first try, the marble bounced out of the tube. We came up with a solution; use a cup at the end of each track to stop the marble from flying out. This did not work, the marble got stuck in the cup. We then tried turning the cup to have the bottom face the marble… IT WORKED! We did this on all track parts and the marble made it down the “mine train”. We will decorate it later.
We moved a small cabinet next to the wall to start our next part “Thunder Mountain”. We build a marble run and connected the wall track to the top of the mountain. A few times the marble bounced out of the track before it got to the mountain. We used extra paper and tape to stop the marble bouncing out. Right now, it looks just like a marble run, we need to make it look like a mountain with paper or something.
After the mountain the marble goes down a long tube and our idea was to have it hit a car, that would then go down a ramp to hit dominos to set off the next step. The car would not stay on the ramp because it was too heavy. We tried to put some tape on the ramp but it did not work. We then tried different balls. the ping pong ball worked best with a tunnel around it to stop it from falling off the track. The Ping Pong ball goes from the track to the dominos. The Dominos and long tube we called “Splash Mountain”. Next stop is the “Tower of Terror”. This is a pulley. We watched a youtube video on how to make one.
We followed the instructions on the video and made the pulley. WE had Alexa’s brother and his friend help us build a tower to hold the pulley. We then tried all the steps of the project to see if they worked. You can see that in this video.
I think we learned so much from this day. The way we had made our sketch and how it really worked was different, we had to come up with new ideas all the time.
Next week we are going to make the pulley move up, build more and decorate.
When I first heard of the Rube Goldberg project I was really excited. My first blog is about the many decisions we had to make. Who to work with? What theme to pick and where to do the project?
I chose to do this project with my friends, Alexa and Maya. We made this decision at school when we first heard about this project. We talked about it at school but when we needed to get together it was hard to find a time that was good for all of us. Because of this Maya decided to do the project by herself. This was not an easy decision for anyone to make.
Whe then had to pick a place to work. We have decided to to work at Alexas house because she has all the tools and the space so we did not have to move the project. Her basement has many building supplies and she has a lot of cardboard which can help with the project. We can build the project in a place where we don’t have to take it down for a while.
For our project theme we picked Disney. We picked Disney because we thought it would be cool to make all of the rides and use the Disney theme. We thought that we would make our project take place in the different Kingdoms. We decided our goal of the Rube Goldberg was to let a balloon with tinkerbell or mary poppins go up in the air.
At the start we decided to research and each think of 2 ideas/projects for our Rude Goldberg. I looked at many youtube videos and researched these websites and videos:
After my research I started to sketch my ideas. We agreed to both think and draw out 2 steps and get together on Saturday to work them out. My idea was to start at the wall and have a marble go down into a mountain like structure. I will tell you about the building in my next blog.
This week it was a very special week. I was kindness week! Kindness week is a challange to see how many kind things you can do such as : smiling at 25 people or slipping a nice note into a friends backpack or locker
During kindness week I said hi to 25 people and and I complemented a friends sibiling about how they were amazing at art. he was very happy when he heard that I also helped the P.E teachrer mr.borgia with the P.E class equitment during battle ship. I just want to say, “If you have the choice from being kind and being right choose right.
