Modelling a hydraulic system

Classroom Activity for 11-14 Supporting Physics Teaching

What the Activity is for

Building a model of a hydraulic system using VnR.

The purpose of this activity is to use a simple modelling tool to model the behaviour of a hydraulic system.

What to Prepare

  • the modelling program VnR running on a computer connected to a large display
  • three prepared models, support sheet (see below)
  • the interactive object (see below)

What Happens During this Activity

Show the interactive object, drawing attention to the connections between the tube diameters and the forces. Then allow the pupils to work with the modelling tool VnR, using the support sheet to guide them. This leads them through three models closely related to the interactive objects – so it may pay to keep this on the large display – then challenge them to build one of their own.
