We have to do a project revolving around the chemistry of metals (could be any metal in any form), which should involve doing experiments. It could be pure investigation or it could be developing something "new" (eg. a more environmentally friendly way of doing something, a new method to save materials, a new type of use for a material).
I would like to use some directions in starting the research for this project. There isn't much we could do in a high school lab (eg. no nano materials, expensive metals, dangerous procedures or high-tech equipments), and we don't have extensive chemistry knowledge to really think of something "new" and "original", as it is required. I'd be very very grateful if you could suggest some ideas which I could look into.
