Program Management System - 21st BCCE - Use of the Submersible, Audible Light Sensor in Chemistry Experimentation

Workshop Title: Use of the Submersible, Audible Light Sensor in Chemistry Experimentation
Descrption: Demonstration of how the Submersible Audible Light sensor (SALS) can be use in chemistry experiments to convey useful information non-visually by means of an audible tone output. The SALS can be used to detect the formation of a precipitate to indicate to students who are blind or low vision when a color change has occurred. Several commonly used experiments will be used to demonstrate how the SALS can create a multi-sensory learning experience for all learners.

Commercial: No
Number of times to offer workshop: 1
Day: half day
Fee: $20
Minimum Participants: 8
Maximum Participants: 20
Room: BIOL 111
Session: Tuesday Morning [2010-08-03 09:00:00 - 11:50:00]
Space: Teaching laboratory preferred
Computer: No
Demo: The iodine clock reaction will be performed as part of this reaction to illustrate the detection of color changes. The use of potassium iodide in conjunction with sodium thiosulfate and ammonium peroxydisulfate solutions are utilized in this experiment. The SALS will also be used as an acid base indicator. The indicator will be phenothalein used in conjunction with acetic acid and sodium thiosulfate solution.
