![]() ![]() Before students go to this site, it is suggested that they be referred to test if the have Java, and download the plug-in if they do not. Students will need to have Java applet plug-in present. (Will first time users fine it easy to use?) Technical Remarks: Specifically address the following issue:ĥ. If properly used as a lab simulator, it could reduce the risks of lab accidents with acids and bases in real laboratory situations.Ĥ. I would highly recommend it for online courses or as a practice run prior to having students actually use acids and bases in a real laboratory setting. If used properly, this lab would be very useful in understanding the various lab techniques as well as principles of pH scale and neutralization. (If used appropriately, will students learning and faculty's teaching be enhanced?) The potential effectiveness for enhancing teaching and learning. I think a brief tutorial is necessary to have students get accustomed to the workshop, using the mouse to gather and handle equipment and reagents, as well as become familiar with the lab bench and pH meter and other log based read outs.ģ. Also, the presence of the thermometer and Log of the different ions provides a good tool to teach exothermic reactions between acids and bases as well as the time course of the changes of various ions during the chemical reaction process. The handling of the lab equipment is straight forward and the array of reagents (mostly acids and bases and indicators) provide for the development of a variety of labs on acids, bases, neutralization, indicators, conjugate bases & acids, as well as possible experiments on dilution of acids & bases, and formation of precipitates. (Do the materials accurately present concepts and models that are educationally significant?) Spent about 30 minutes browsing site and performed simple titration lab using HCL and NaOH with Phenolphthalein as indicator (using Buret).Ģ. How did you review the materials? (Did you spend 5 minutes browsing or 2 hours trying it?) ![]()
