Balancing Sculpture Level 2
Balancing Sculpture Level 2 https://www.tinkercad.com/things/5TAjMzgZZE6-thin-skewer-ends/edit?returnTo=%2Fdashboard%2Fdesigns%2F3d Days: 1 Mode: Individual Take-home: Large balancing sculpture
Teaching & key ideas
Key concepts: Center of mass, torque, lever arms, counterweights, stability.
Hook: Show a deliberately bad example and an exaggerated large balancing example.
Test / evidence: Sculpture balances reliably from a narrow support point.
Variables to change: Counterweight mass; distance from pivot; crossbar length.
Lesson flow
Lesson plan:
Day 1: Center-of-mass demo → assemble crossbars → add counterweights → balance → deliberately move one weight and retest
Safety / cleanup:
Teacher manages sharp skewer ends; use printed end caps; keep weights securely attached.
