Demonstration: Discussing the effect of area on pressure.
Class practical: Observing that air springs back when the pressure on it is released.
Demonstration: Does the area of a manometer tube matter when measuring pressure?
Demonstration: Using U-tube manometers to measure the gas supply pressure.
Class practical: Feeling forces with two nylon syringes of different sizes connected together.
Class practicals: An experiment to introduce the Bourdon gauge.
Begin with some simple questions in order to find out what students know about pressure and so determine a starting point for...
This activity provides a vital set of experiences and an introduction to pressure as a large scale measurement of the state of...
Here you can show that there is a connection between the force generated, the area over which molecules bombard a surface and...
Here pupils can feel for themselves the change in forces that results from a change in area, relating this to the number of...
The purpose of this activity is to use a simple modelling tool to model the behaviour of a hydraulic system.
Recognising and celebrating outstanding contributions to the field of physics education.
