Vernier Caliper JS Model
written by Jiun Wei Chia
The Vernier Caliper JavaScript Model shows the principle of operation and the physical parts of a Vernier Caliper.

The Vernier calipers model has
• an object (Blue) for the internal jaws to measure width of an object with slider to control width of the object and simple drag action to control position of object.
• an object (Green) for external jaws to measure internal diameter of a cylinder for example with slider to control dimensions of the cylinder.
• checkbox for answer to show the meaning of reading on the main scale and the vernier scale with zero error calculations if any.
• drop down menu of the various common vernier scales for sense making and additional testing out by learners their ideas of how vernier works.
• fine <> control buttons for learners to manipulate the model with single incremental precision
• slider control for fast changes in the vernier measurement
• reset button to bring simulaton back to original (default)
setting.

AAAS Benchmark Alignments (2008 Version)

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.
