Rube Goldberg Machine

Choosing my Project (Entry #1)

What did I choose?

Rube Goldburg Machine.

Why did I choose?

I thought it would be really fun to make longer machine than what we made in class.

What I want to learn?

I want to learn how certain movements can have a chain reaction to perform a task.

Would I like to do this as a Career?

No, because I do not want to be an engineer.

Intro Research (Planning)        (Entry #2)

What did I do to plan/learn about my project?

I watched numerous videos of other Rube Goldbbrg Machines to find ideas.

Intro Research Part. II (Entry #3)

What kind of information did you learn to help complete your project?

I learned how to take different ideas from the machines i saw and put them together into my own.

Questions Answered (Entry #4)

What did you do? We made our sketch.

Upload a photo/video.

What question did you answer about how to complete your project? We came up with the final task of the machine.

What you are finding out while doing your project (Entry #5-6)

We are having difficulties making our first two stages working together. Also while making our stages, it is hard to make the objects the same & neat.

What SPECIAL terms (technical) do you need to know? (Entry #6-7)

You need to describe any specialized iteams and any terms you may need to know.

Pulley- is a wheel on an axle or shaft that is designed to support movement and change of direction of a cable or belt along its circumference.

Momentum- the impetus gained by a moving object.

NEW questions and information (Entry #8)

We need to know how to make smooth transitions between stages.

For one of our new stages, we are using water to soak a paper towel so an object can drop through, we need to research and experiment to see how much water we nee, what type of paper towels, and what cup will fall easiest.

Technical Parts Of Your Project (Entry #9)

Our final version of the project includes shoe boxes, a slinky, a large marble, a track, a pulley, a zip line, a counterweight, paper towel, a large weight, a bottle of toothpaste, and a toothbrush.

Technical Stuff Part 2 (Entry #10)

The actions of our project are explained here:

YOU Decide (Entry #11-13)

The last 3 days have been somewhat hard. We dont have all the supplies right now so what we can work on is limited. WE have also changed some stages in our original sketch, adding a slinky, a zip line, and a different way to get the toothpaste on the toothbrush.

YOU ARENT DONE! Where Do You Go From Here? (Entry #14-15)

To go further with our project, i would like to connect with another groups machine. Also, i would like to make the end task harder, or bigger. I think it would be cool if we made a machine going around the school, not just in the stem room. Over the summer i can get with my group & maybe come up with something and post it here.

Did it Work? (Entry #16)

YES/NO our project worked because every stage worked and we had them all together, we just couldnt hold up the pulley until the marble hit it.

Reflection (Entry #17)

What i learned;

-for the wheel of a pulley to stay on the zip line and roll, you need a COUNTERWEIGHT

-use your time wisely

-no matter the size, an object needs build up momentum in order to push a different object

-neat stages=well working stages

-be open to new ideas

-your project needs to go through lots of changes until its perfect

-you can never have enough supplies

How did my project turn out? Well our project turned out pretty well, all our stages were built and set up. The reason it didnt work is we had nothing to hold up the pulley before it went down the line.

no, because it was very hard for me to understand and build.

yes, i woudve preferred the drone because it looked very fun and im good at electronics.
