Instructional Ideas

• Break out some inexpensive syringes and let students conduct similar trials before using the simulation
• Ask pupils to describe why the plunger is pulled back into the capped syringe when they let go of it

Classroom Considerations

• Discuss the properties of gases and gas particles to be sure pupils understand them before launching the interactive
  

Pros

• A bright yellow arrow helps learners keep track of the direction of movement of the plunger
• Options abound with a variety of user-controlled settings

Cons

• None
