Pressure and volume are in a relationship, but what is the nature of it? High school scientists discover the link between the volume of a gas and the pressure it exerts using a simulation. The resource tracks pressure in a sidebar as learners move a barrier to increase or decrease the volume of the container.

Instructional Ideas

• Assign the interactive as an inquiry tool and allow pupils to draw their own conclusions about the volume-pressure relationship
• Ask the class what type of relationship, linear or inverse, the interactive illustrates
  

Classroom Considerations

• Make sure students understand the units of volume and pressure used in the resource
  

Pros

• Makes viewing the quantity of pressure possible, which is often difficult due to the invisible nature of most gases
• The interactive is easy to manipulate

Cons

• None
