General Hints & Strategies (All Year Groups)
Sketch first: Encourage each class to draw a rough plan of their section (input, mechanism, output) before building. This helps clarify which direction things should move, where supports are needed, and how to link to the next section.
Modular bases: Build each class’s mechanism on a separate cardboard base or platform (e.g. a stiff sheet or shallow box) so they can be joined easily.
Test frequently in small steps: After building a small part, test it before adding complexity. This helps isolate problems early.
Use adjustable supports: Use extra bits of cardboard, scrap pieces, or Makedo to shim or fine-tune angles.
Balance robustness and flexibility: Be firm enough so parts don’t collapse, but leave some “give” (loose joints, lightly taped pivots) so small adjustments are possible.
Document “failures”: Encourage pupils to note what didn’t work and why. Iteration is part of engineering.
Connect clearly: Ensure that each section has a well-defined “handover point” — for example, a ball exits this class’s mechanism and lands or triggers something in the next class’s mechanism.
Time / stage management: Allocate time for planning, building, testing, debugging, and linking. Don’t skip the testing phase.
Encourage creativity & choice: Even within constraints (cardboard, Makedo), allow pupils to vary shapes, colors, themes — this increases engagement.

👶 Nursery to Year 6: Hints, Pointers & Web Resources
Below is a breakdown for each year, with stage-specific hints and possible linked resources to support teaching & learning.
Nursery
Focus: Rolling / object creation and exploring motion
Hints & Pointers:
Provide simple templates or stencils for circles or cylinders to make rolling shapes.
Test on small ramps to see how well they roll (flat surfaces, incline).
Encourage exploration: e.g. try balls vs cylinders vs tubes, see which roll more smoothly.
Let children decorate their rolling objects (colour, patterns) to observe how uniform shape affects roll.
Resources:
As inspiration: “Build Your Own Goldberg Machine From Cardboard!” gives simple slide/ball ideas.
“TinkerLab: Engineering Kids – Rube Goldberg Machine” offers ideas on how to make simple chain reactions with young children.
---
Reception
Focus: Ramps, slides & inclined planes
Hints & Pointers:
Start with gentle slopes; test with nursery’s rolling object to see how far/fast it goes.
Try varying angles and measure speed (e.g. mark start and end points).
Add side-walls to ramps (using folded strips) to keep the ball from falling off.
Test transition from ramp end to next mechanism (e.g. ensure ball lands cleanly into a trigger or flap).
Encourage pupils to adjust angle (raise or lower one end) to fine-tune motion.
Resources:
TeachEngineering’s “Engineering: Simple Machines” lesson gives solid background on inclined planes and other simple machines.
Instructables article “Build Your Own Goldberg Machine From Cardboard” shows how to build slides and sequential steps.
Elementary Nest’s collection of simple machines project ideas, including ramps/inclined planes.
---
Year 1
Focus: Flaps, drop gates, seesaws, simple triggers
Hints & Pointers:
Use Makedo hinges or folded strips for flaps; allow for smooth pivoting.
When using seesaws, ensure the fulcrum is stable (e.g. a glued dowel, tube, or stacked cardboard).
Use light materials (thin cardboard) for moving parts so triggers respond easily.
Add “buffers” (small cardboard lips) to guide the ball onto a flap or see-saw without it bouncing off.
Test the trigger — sometimes the ball may not have enough momentum; adjust heights or drop distances.
Resources:
Instructables’ cardboard Rube Goldberg machines includes flap and tilt ideas.
“Build a Simple Rube Goldberg” blog includes simple lever / seesaw suggestions and how to chain parts.

---
Year 2
Focus: Domino chains, lever lifts, cascading movements
Hints & Pointers:
Dominos: make sure they are uniform height and stable; test in short lengths first.
Levers: attach a small tray or platform to one end so a ball or object can land and tip it.
Use short strings or light connectors to help the motion transmit (e.g. pull tabs).
Consider combining a domino effect into a lever (i.e. last domino knocks lever).
Use trial runs with slightly larger objects first to test the force needed.

“Build a Simple Rube Goldberg” shows combining dominoes and levers in chain reactions.
TeachEngineering simple machines lesson (lever, wheel & axle, inclined plane) for conceptual background.
Elementary Nest project ideas include linking simple machines (e.g. lever + wedge + pulley) for kids.
---
Year 3
Focus: Wheels, spinners, pulleys, rotational motion
Hints & Pointers:
Use cardboard discs around a central pivot (Makedo screw or dowel) for wheels/spinners.
Add vanes or paddles to increase surface area so a light object or ball can turn the wheel.
For pulley ideas, use string and simple loops; ensure smooth path without too much friction.
Keep rotating parts well-aligned; test with light loads first.
Use “idler” wheels or guides to keep string from slipping off.
Resources:
TeachEngineering’s simple machines resource introduces wheel & axle, pulleys, levers.
Instructables’ cardboard Rube Goldberg projects often use wheels/discs and string mechanisms.
The “6 Great Simple Machines” page includes ideas and visuals for wheels, pulleys, and more.
---
Year 4
Focus: Funnels, spiral ramps, cam motion, converting rotary to linear motion
Hints & Pointers:
For spiral ramps: cut long strips and curve them into spirals, use supports underneath to hold shape.
Funnels: use concentric circles or cut rings and stack to approximate a funnel shape.
If introducing cams (eccentric circles): the cam should push gently on a follower arm; start with a small offset and test.
Use smooth surfaces (cover cardboard with tape or smooth paper) to reduce friction.
Test clearance: moving parts should not rub too much, should have slack or bearing points.
Resources:
Instructables’ “Build Your Own Goldberg Machine From Cardboard” includes example ramps, curved paths.
“Build a Simple Rube Goldberg” suggests combining ramps, pulleys, and tipping mechanisms in creative ways.
Elementary Nest’s simple machines resource has extension ideas for intermediate students.
---
Year 5
Focus: Multi-level chutes, towers, switches, alternative paths
Hints & Pointers:
Use stacking and layering of cardboard to create vertical drop paths.
Add flaps or “switches” (hinged cardboard) to divert the ball or object along different branches.
Use “funnels to chute” transitions carefully — align edges precisely so objects don’t snag.
Use guides (side walls) to keep the ball in the intended path.
Test slow vs fast runs: sometimes slowing the object helps more reliably trigger next stage.
Use redundant triggers (e.g. two small flaps) to increase reliability.
Resources:
Instructables’ cardboard Rube Goldberg machines includes multi-level drop paths.
“Build a Simple Rube Goldberg” blog highlights how to chain multiple mechanisms and tiers.
Elementary Nest’s extension ideas often include more complex switches or alternative path control.
---
Year 6
Focus: Final triggers, system integration, refinements, aesthetics
Hints & Pointers:
Encourage students to review the entire chain — see where weak spots or time lags may occur.
Build in buffers or delay mechanisms if something triggers too fast or too slow.
Add final dramatic effect (e.g. knocking over a sign, lifting a flag, ringing a bell) — ensure it’s lightweight.
Use decorative elements, theming, and story so the machine is visually engaging.
Time the run and make slight adjustments (angles, friction, mass) to improve reliability.
Let students reflect: what section was most problematic? What would they redesign next time?
Resources:
Connections Academy’s “Steps to Build Your Own Rube Goldberg Machine” gives general scaffold and encourages iteration.
Instructables’ “Cardboard Rube Goldberg Machine” shows a completed example from start to finish.

🎓 Pedagogical & Curriculum Links
Use the “simple machines” concept (lever, wheel & axle, pulley, inclined plane, screw, wedge) as a backbone for teaching mechanical thinking.
Use jigsaw activities to allow students to become experts in one simple machine and teach others. (See “Simple Machines Tour Educator’s Guide”)
Use anchor charts and visual displays of simple machines and examples around the school (tools, playground, carts) to reinforce cross-linking.
