Map the mechanism
Give each stage an input, a physical process and an output. Name the simple machine where one is used. A rolling ball does not explain the next action until you show what it hits, lifts, releases or turns.
Rube Goldberg
A simple task. An inventive sequence. A clear explanation.
DESIGN STUDIO
A chain of causes, not just a chain of objects.
Choose a simple final job, such as ringing a bell or moving a small flag. Design a sequence in which one action triggers the next. Explain what changes at each stage and test whether it happens reliably.
This studio supports your planning. Use your teacher’s current project instructions for required materials, criteria and deadlines.
Track the energy
Identify the original energy store. A raised mass, stretched elastic or battery can provide an input. Each stage transfers energy, with some becoming less useful. A long sequence needs enough energy and reliable triggers to keep working.
Test one link first
Build and test each transition separately before joining the whole sequence. Keep a record of successful attempts and the reason for each failure. Change one variable at a time so you can connect an improvement with evidence.
Design for safe repeatability
Use stable supports and teacher-approved small loads and materials. Avoid flames, exposed electrical hazards, projectiles and pressure vessels. Keep hands away from pinch points. Choose a final action that you can reset and test fairly.
Connect every stage
Record the cause and effect. This plan saves on this browser only; print or copy it before changing devices.
Keep a test record
- State the change: move the lever pivot 2 cm, for example.
- Predict the effect on effort, movement or trigger reliability.
- Run repeated trials under the same conditions. Record successes and failures.
- Explain whether the evidence supports your change and what you would test next.
A successful final action matters. So does a clear scientific explanation of why the mechanism works.
