City in
Motion
ACTIVITY PROMPT
Your city shouldn’t just look futuristic — it should feel alive! In this step, you'll add simple moving parts using cardboard, paper, and basic joinery techniques.
ACTIVITY MATERIALS
- Sturdy material for the 3D sculpture (thin cardboard, 180g paper).
- Cutting tools (scissors, craft knife, etc.)
- Ruler and pencil for measurements.
- Glue/tape (glue gun or craft glue)
- Rubber bands, zip tie, brads
- Popsicles and white string
ACTIVITY STEPS
1st
30 min
What parts of a city might move in the future — not just for fun, but for purpose?
Think of those question and get inspired.
- Can a part of your building rotate to face the sun?
- Could a roof open and close like a flower?
- Can the building lift up or shift position during a storm or sandstorm?
- Do cars or pods travel along ramps or tracks?
- Can roads rise or split to let people or water pass?
- Is there a moving walkway or slide that helps people move faster?
- Is there a kinetic sculpture that reacts to wind or touch?
ACTIVITY STEPS
2nd
~ 5hrs
Choose and Plan 3 Movements
- Pick 3 movements to prototype.
- What materials will you need (cardboard, pins, string, etc.)?
- Draw a quick diagram of how the movements will work (e.g., spinning, sliding, folding).
- Learn how to recreate those models in the next slides!

Finalize your city piece!
- Connect your moving part to your building or city base.
- Make sure the movement still works!
