This is our first STEM project. The Rube Goldberg Machine. Which includes a very complicated multi-step process that completes a very simple task. Ours had seventeen steps just to crack an egg.
CONCEPTS
Force: Force is a push or pull. You can find force by multiplying mass by acceleration. We used force when we needed to find what force we need to hit a button.
Work: Work is a force that is put on an object to move it. You can find work by multiplying force time distance. We used work when work when we the marble hits the button to release the car.
Impulse: Impulse is how much force is put on a object. You can find Impulse by multiplying force by time. We used Impulse when the weight is dropped onto the egg by the pulley.
Momentum: Momentum is equal to Impulse. So momentum is equal mv, which is mass time velocity and Ft, which is Force times time. We used momentum when the marble rolled down the wall track.
Power: Power is how long someone or something is doing work on a object. You can solve by dividing work over time. We used power when the toy car hit the block of wood.
Distance: Distance is how far something is from another thing. You can find distance by half of the acceleration due to gravity times time squared. We used distance when we wanted to know how far something is from anther thing.
Acceleration:Acceleration is the change in velocity with respect to time. You can find acceleration by dividing force over mass. We used acceleration when the marble fell off the ramp into the lever.
Mechanical Advantage:Mechanical Advantage is how much easier a machine makes work. You can find MA if you divide input distance over output distance. We used MA when we used a lever.
Potential Energy:Potential Energy is the amount of energy the object has in relation to the height. You can find PE by mass times acceleration due to gravity times height. We used PE when the marble sat at the start of the machine.
Kinetic Energy:Kinetic Energy is the energy an object has. It equals Potential Energy. You can find KE by half of the mass times velocity squared.
Velocity:Velocity is the change in a body's position in a certain direction. You can find velocity by speed with direction. We used velocity when the car road down the track.
During our project there were many peaks and pits. On peak was that we all contributed all our ideas into the lego lever we had to make it work. Another is that at first we didn't have anything to do with the dominoes. We all collaborated to figure out a creative and efficient lever. One pit that we had was having our last step include water. We couldn't do this because we could find anything that was water sealant and let objects slide.
During the project I learned that I really liked to talk and share all my ideas. No matter how stupid. I also learned that I don't want to ever give up on anything, even if I know that it is not possible. I also learned some things that I can improve on. I learned that I can get off task easily and goof around. I found out that I don't like people telling me what to do. I would just rather do my own thing.
I feel my group and I, which consisted of Sawyer,Toby, and Cate worked like we knew each other for a long time. We sort of knew each other at Sinaloa but we were pretty much strangers. We all were able to listen to each others ideas and find ways to incorporate them into our project. This made our project unique and it resembled everyone in our group. My group can improve on being positive through hard times like we were all getting angry at each other when we were trying to get the project done by the deadline. Overall my group and I were able to get the project done and learn new skills through the process.
Our project had many ups and downs. We started off really slow. We were still on our first step after about three hours. Our first step was to draw a grid to help us with the calculations and scale drawing. Then we cut the wood in half for a wall and a bottom and nailed them together. After that we started to hang the wall track. Our first problem was that the glue that the wall track came with didn't stick to the wood and it kept falling off. We solved that by using lots of tape.
After that we we ran into another big problem. Getting the marble to come out of the screw, hit the inclined plane and then knock over the dominoes. We found that maybe putting sides on the inclined plane. We experimented with that and we found that it worked. So we put tiny wood sides on our inclined plane.
Our biggest problem however was the lever or the catapult. We had lots of trouble getting the marble to land in the firing space. We also had trouble getting the lever to fire by itself. We found that if we put a stick under the mass to hold it up and have the dominoes hit it over. That was difficult because we had to have the marble land in the lever before the dominoes set it off. It was also very hard to have the lever to consistently land in the funnel to hit the button. We solved this by placing the lever close to the funnel to adding accuracy and therefore making it more consistent.
Our Rube Goldberg consisted of 17 steps. Starting of with a wedge blocking a marble, the marble is released and roles down a wall track and hits another marble. Then, the first marble fall down a funnel and into a screw. The screw then launches the marble down an inclined plane and hit dominoes which causes a chain reaction of toppling. The dominoes then gradually get bigger and not over a pole holding up a lever. While this is al happening, The second marble hit in the beginning is now traveling down a ramp and going around a switchback and launches out and lands in the lever that the dominoes knock over. After all that, the marble that landed in the lever is launched to a funnel that then drops down a tube. That tube is guiding the marble to hit a button to release the car. Now that the button is hit, the car travels down the car track and hits a weight on top of a domino, which is on one side of a pulley. Finally that weight is rolled off and it releases the pulley to drop another weight on an egg. This reaches are end goal of cracking an egg.
