Which Tank Fills First?

Can your class solve the riddle? A video from the Physics Girl playlist tackles the puzzle of Pascal's Principle. Viewers observe as a series of connected tanks fill up and try to guess which will fill first. The narrator shows the design process and explains how changes to pressure within the system are carried throughout it.

Instructional Ideas
  • Show the experimental setup, then ask the class to make their predictions before showing the video
  • Place learners in groups and have them design and construct their own Pascal Tubes
Classroom Considerations
  • Learners need very little previous experience with Pascal's Principle
  • The resource presents a challenging scenario in a fun, engaging way
  • Diagrams and demonstrates Pascal's Principle, making it easy to understand
  • None
