Rube Goldberg Machine

Step 1: Pull the train ( Mechanical, as it is just pulling, Magnetic because of the train’s magnets which connect it to another train.)

Step 2: The train is attached to the pulley, which is attached to a track that lifts ( Gravitational, as it is a pulley which incorporates something falling to let the other rise, then Mechanical as it results in an object moving mechanically; Track rising)

Step 3: And the marble rolls because of the incline. (Gravitational, so the marble rolls down because of gravity. Then Mechanical, because it rolls.)

Step 4: The marble lets a pre-turned on toy train go, which knocks over a calculator. (Mechanical, as it is moving, Chemical, because of the battery power source, Electrical, for the electricity produced to make it go in the first place.)

Step 5: A pulley attached to the calculator will rise when the calculator drops, which lifts a track. ( Gravitational, as it is a pulley which incorporates something falling to let the other rise, then Mechanical as it results in an object moving mechanically; Track rising)

Step 6: A toy train with no batteries falls due to the incline. (Gravitational because it is falling downwards due to gravity, and  Mechanical since it is running on the tracks.)

Step 7: The toy train spins on the track and lands on a lever. (Gravitational because it falls down onto the lever and Mechanical as it results in the train running on the tracks.)

Step 8+9: A pulley that is attached to the lever and a pen drops, so when the toy train lands on the lever the other end goes up, making the pen fall to touch the surface of the cell phone, playing a short sound of applause in congratulations of finishing the cycle. ( Gravitational because the pen falls to touch the surface of the cell phone. Mechanical since the overall motion is the pen falling. Chemical, as the cell phone has Chemical parts, Electrical because of the Chemical parts creating electricity, and Sound as it is produced when the pen touches the cell phone.)

 

Core Competency Reflection:
-Analytical Thinking

I believe that I applied this throughout the whole planning and creation process. The machine needed to be creative but work in the end with no mistakes.

-Creative Thinking

I had a long time struggling with this part, but it was crucial and needed to make the ideas come to life. Simplicity but creativity is hard to balance, so finding the right solutions and making ideas stable was a challenge.
