  1. Drag the slider to increase and decrease the amount of medication in the syringe.
  2. Observe the changes in milliliters (mL) and evaluate the values of the lines. 
  3. To test your ability to read the syringe:
  4. Select the green HIDE/REVEAL button to hide the amount of medication
  5. Set the slider to any position on the syringe
  6. State the amount of medication aloud 
  7. Select the green HIDE/REVEAL button to show the answer and confirm your accuracy

While learning through lectures and readings is beneficial, sometimes the best learning strategy is to tinker and experiment with interactions and simulations. With this virtual tool:

  • Students learn how to read syringes simply by experimenting with the slider and observing its impact. 
  • Educators foster student engagement and participation by presenting this tool during web lectures or in the classroom using a digital projector.

You can find our collection of virtual syringes and other virtual tools in our flagship course—The Ultimate Head Start in Healthcare Career Training.
