This is a Rube Goldberg Machine. The purpose of a Rube Goldberg Machine is a contraption, invention, device or apparatus that is deliberately over-engineered or overdone to perform a very simple task in a very complicated fashion, usually including a chain reaction.
I choose to do a Rube Goldberg Machine with Olivia and Jacey. I chose to do a Rube Goldberg Machine because I like problem- solving and finding complicated ways to do simple tasks. I want to learn how to solve problems. I would not like to do this for a career because im not good at it, but i would like to learn more and I dont like machine working.
I looked up videos and pictures, researched information, I got a book from the local book store and read all of it. I also asked my peers and adults about it.
I watched a video to learn how to use my materials wisely, different ways of bringing the ball down, and how to use different types of tracks. I read a book on the history of Rube Goldberg and facts about it to learn more about what im making. I looked at pictures of beginner Rube Goldberg machines to get some good ideas. I researched information to learn about what stuff to use and what some good ideas are.Our ideas we had are was to have an object roll down a chute of some sort, knocking down objects like a chain reaction. Then have the objects fall down then pushing another object like a lever.
We made a ramp and set a ball on top, so it could roll down. Then it will knock down the foam board with pennies. The dominoes will push another ball down into a cup that has a hole on the bottom. Next the ball will fall though and land on the board that its balancing on a platform. On the other end of the board there is a balloon that will be escalating up to a needle that will pop the balloon.
Today I learned different strategies and how gravity affects it. We drew out our machine and labeled the motions of energy. We labeled the energy transformations. Tomorrow we are bringing in our objects and bringing our drawing to life!!!!!!!
Today we brought materials to start our project. We are first gonna lay them out and see what our lay is gonna be. We brought in a golf ball, ramp, foam board, pennies, bouncy ball, cup, teeter totter, a balloon, and a needle. We layed them them out and plotted how to start buliding the machine. We drew out our ideas and fixed the problems we had and made some adjustments.
Today, we bulit our machine and it failed. We tried the balloon poping at the end and realized the needle needs more pressure on it. But, we don't know how to fix it. So, we are going to make some fixes and a get a new task and adjust to it. We are going to get more supplies tonight and bring them in tomorrow and work with what we have and look up some more videos.
Today we built our first stage. We used foam board and duct tape. We cut the foam board in half and taped it together on a slant.
Today we tried to follow up with our third planned out stage, which was for something to knock down a golf ball from a table onto a teeter totter. The other end of the teeter totter had a blown up balloon which would be raised up and hit a needle which would pop the balloon. That idea did not succeed. However, we made it work, but with a few changes. To fix the machine we would either need a thicker needle, or add more pressure to the suspended needle. We ended up changing our machine stage completely.
Today we successfully built the first three stages of our machine. The first stage was a ramp that the golf ball rolls down then hits boundary 1 and boundary 2. Boundary 1 is made out of foam board. Boundary 2 is made out of wood. The ball hits the boundaries and rolls down the table into a red cup. The ball rolls through the cup and hits the next stage in which we are currently creating. Here is a video of our completed stages.
Today we successfully created stage 1,2,&3. Stage 1 is a golf ball rolling down a ramp. The golf ball will then roll down the table and hit boundary 1 and 2, creating stage 2. Stage 3 is when the ball hits boundary 2 and rolls into the red cup then falls to the ground. We did research on how to successfully make a Rube Goldberg from start to finish. One thing we read about was that after the ball dropped through the cup it should land on a book that has a balloon on the middle of it. When the ball lands in the cup that is on the book, it will lean down so the balloon on the opposite side will rise 2-3 inches off the ground.
Today we tested out the new things we learned about. It surprisingly worked. The balloon raised about 3 inches and hit a nail. We decided to change the needle into a nail because it is sturdier and pops the balloon without much pressure. We still need to figure out stages 4&5 which we are doing tomorrow.
Today we adjusted and re-did our machine. The ball rolls faster, there are less objects in the way which gives it a sleek look. We are making changes to our step 4. Tomorrow we will add a few items and try to modify more.
The modifications we need to figure out is a way to have the golf ball roll directly in the cup each time. So the things that we had modify was that the ball will roll down the ramp and hit the board. Then the ball will hit a block that is in front of another golf ball. After the ball hit the board, the board will knock the other golf ball into the cup.
We had made some modifications in our machine. We had add a line that something can slide down it and knock the ball off the ramp. However, this sometimes don't work, so we need to make sure it works everytime.
Today we had modify our first 2 stages on our machine. We had to move the string so the slider can successfully slide down the string without anymore help. Also we rebuild our ramp, too, because we needed a clean slate so the ball could successfully roll off the stage and down the ramp.
Today was not a success at all. None of the stages that we had set up work for us. Also we had tried to add in the extra stage, but it didn't work for us either. So I would say that our Rube Goldberg machine was not successful.
Our machine didn't work out in the end. We had to add some stages and take away some stages. We tried to get it to work, but we tried everything and it was too late to get new materials and redo the whole thing. This project did not make me want to do this more because its not fun for me and I'm not good at it. I'm glad I did this project because I learned how to work with the materials I have and to problem solve. Overall I had fun with my friends and it was great to work with them.
