As I was getting ready to submit my update I noticed that I had posting to my own blog and not this one.  Below is the link to my blog page where I have been posting throughout the week.

However, here is my weekly update:

The second week is all gone and so much left to do.  In the lab we have continued to search for chelators that can bind to TiO2, but they must remain in suspension in order to develop a quantifiable colorimetric detection of TiO2 in aqueous solutions.  Several chelates/ligands have displayed some promise.  Now we are examining the stability of the ligands by manipulating the pH.  It has been a tedious process, however, I could not think of anything else I would like to be doing over the summer.

As for my lesson, I have found a topic.  It is based on the chelating properties of certain plants (specifically cilantro)and how they can be used in the water purification process.   Attempting to establish a lesson relating to water purification, chelates, and green chemistry.  Cross-referenced on teachengineering.com and a lesson like this has not been developed.  Took it a step further and searched on the American Chemical Society education website and the same result.  Next step is to align the lesson objective to the Next Gen Standards and the State Standards.  Until next time!  Hope all is well for everyone else.
