Testing for the pH Factor in Liquids using the LabQuest (1st Version)

This is a short four-part video demonstrating how students in a science lab at the Texas School for the Blind and Visually Impaired use the LabQuest equipment from Vernier Science .  They are finding the pH factor of four liquids: distilled water, tap water, milk and vinegar. The data collection device used in the experiment is the stand-alone LabQuest-Version 1.   LabQuest 1 is the only Vernier device that “accepts” the Sci-Voice scripting software.  With Sci-Voice installed, the LabQuest 1 device is able to voice the data.  This enables the student with a visual impairment to hear the incremental changes relative to time of any experiment that is recorded by a sensor probe used in conjunction with the LabQuest device.  Discerning the change in incremental findings of substances as they occur in real time is essential to laboratory experiments and data collection.   A pH sensor is plugged into one of the...
