  • 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

  • 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
