Rube Goldberg Wedges

thingiverse

Here are the components needed to construct a functioning ninth-grade Rube Goldberg machine: 1. **Base**: A large piece of cardboard or foam board will serve as the foundation of your contraption. 2. **Ramps**: Create ramps using cardboard, PVC pipes, or other materials that can lead from one level to another, allowing objects to roll freely. 3. **Marbles**: You'll need a sufficient number of marbles in different sizes and colors to function as "triggers" throughout the machine. 4. **Pulleys**: Use rubber bands, strings, or small pulleys to move objects along the ramps or through the machine. 5. **Gyroscopes**: Incorporate spinning tops or gyroscopes to introduce unpredictability and make your machine more challenging to predict. 6. **Launchers**: Construct launchers using straws, cardboard tubes, or other materials that can propel marbles, balls, or other objects into action. 7. **Valves**: Add valves made from plastic bottles, cardboard, or other materials to control the flow of liquids or gases through your machine. 8. **Weighing Scales**: Utilize a balance scale or a seesaw to demonstrate the concept of equilibrium and how it can be utilized in a Rube Goldberg machine. 9. **Sensors**: Incorporate sensors like photodiodes, pressure sensors, or motion detectors to detect changes within the machine and trigger subsequent events. 10. **Control Panel**: Design an interactive control panel using buttons, levers, or other controls that allow users to adjust settings, activate different parts of the machine, or even create their own sequences.
