This interactive model shows the principle of operation and the physical parts of a Vernier Caliper, a device used in length measurements to gain accuracy compared to a simple ruler. In this simulation, use the blue slider to move the internal jaws and measure the width of an object; use the green slider to move external jaws to measure the object's internal diameter. The model was developed to help students gain proficiency in use of the Vernier Caliper outside the lab, and to promote understanding of uncertainty and error in measurement.  

This model was developed using Easy Java Simulations (EJS) a modeling tool that allows users without formal programming experience to generate computer models and simulations. Teachers may choose to simply run the simulation, or may modify/customize the model by installing the EJS Modeling and Authoring Tool. SEE RELATED MATERIALS for a link to the free authoring tool.

Please note that this resource requires at least version 1.5 of Java (JRE).

11. Common Themes

11B. Models
  • 6-8: 11B/M6. A model can sometimes be used to get ideas about how the thing being modeled actually works, but there is no guarantee that these ideas are correct if they are based on the model alone.

12. Habits of Mind

12B. Computation and Estimation
  • 6-8: 12B/M8. Decide what degree of precision is adequate and round off the result of calculator operations to enough significant figures to reasonably reflect those of the inputs.
12C. Manipulation and Observation
  • 6-8: 12C/M3. Make accurate measurements of length, volume, weight, elapsed time, rates, and temperature by using appropriate devices.
  • 6-8: 12C/M5. Analyze simple mechanical devices and describe what the various parts are for; estimate what the effect of making a change in one part of a device would have on the device as a whole.
