STEM project: Rube Goldberg Machine
The machine works by using the weight of four marbles to spin an axle. The axle winds a string which is attached to ramp arm. A large marble then rolls off of the ramp arm and initiates a domino train. The domino train includes a set of steps and a progressive domino chain at the end. The final “domino” is holding a group of dice which falls into a bowl of water, making a splash.
Rayne really enjoys STEM activities. So, she likes to get involved in any STEM activity she can. That is what inspired her to build this machine.
