Need idea for science project

I have a science project in grade 12 chemistry due soon...I am interested in electroplating....however, I need to make up a problem...like...what is the effect of temperature or concentration on.... How can I incorporate such a question when dealing with electroplating? Any suggestions? Thank you very much in advance.

A good science project might be to try to develop a "brightener". Plate quarters or dimes with copper, or plate pennies with zinc (the instructions are on line here). And in addition to the vinegar ⇦ in bulk on eBay or Amazon [affil link] and table salt or epsom salt [affil link], add a tiny pinch of various organic materials, one per test, like sugar, saccharin, honey, molasses, hide glue, etc. and see if you can find a brightener that will actually help the plating deposit shiny instead of dull and grainy. If you have any success, we'd like to print it here for future students.
