Acid/Base virtual titration

I like the idea of using a virtual titration to help prepare students for a real titration that they will be doing the next day. I know how challenging this can be for students the first time and I know, even in advanced classes, that they usually screw it up. I think doing it virtually first is a good step to preventing that. In addition, I like how you say this is the first lab where the students will be graded on accuracy because I think that will make the students pay closer attention to the virtual titration in hopes of being more successful the next day. I think the amount of technology you need to do this lesson is very doable and is not outside of the scope of a chemistry class. As a question though, where did you get the virtual titration simulation? Is it a web based application that is out there for free or is it software that had to be purchased from a vendor?

As a suggestion for making this lesson plan better, I believe including some form of state content standards might be a good idea. I know that where I teach every lesson I do has to be directly aligned to some content standard or another and I have to be able to demonstrate that alignment if needed. Perhaps simply finding one and throwing it in there would be a good idea. The only other thing I would perhaps suggest is that you physically have the students practice the act of titrating before grading them on it. I know the virtual titration is designed to help that but at the same time I know how difficult the physical act of doing it is. No amount of virtual training can make up for that. I really like the idea though and would be interested in using the virtual simulation myself.

Technical Remarks:

Technically, everything worked fine in the document itself.  I also believe the virtual simulation would work fine in a high school class.  My only question is where the virtual simulation software is coming from, either web based or purchased software?  Otherwise, no problems at all.
