Communicating Vessels — Same Water Level
Communicating Vessels — Same Water Level https://www.youtube.com/shorts/7cVQw7c4Hug Days: 1 Mode: Teacher demo + small-group investigation Take-home: Optional connected-vessel model
Teaching & key ideas
Key concepts: Fluid pressure, connected containers, equilibrium, gravity.
Hook: Connect three differently shaped bottles/tubes and ask where the water lines will settle.
Test / evidence: Students predict then observe that connected water surfaces settle to the same level when pressure conditions match.
Variables to change: Container shape; connection height; tilt.
Lesson flow
Lesson plan:
Day 1: Predict water levels → run demo → small-group tubing model if feasible → sketch/explain equilibrium

Same Level Of Water On 3 Bottles?
Safety / cleanup:
Water only; secure tubing; wipe spills; use plastic containers.
