For our gen chem lab, we have to conduct an experiment that can done for elementary kids to basically teach them and get them involved/intrigued in science. The main problem is that we got environmental/green/forensics and we have never studied or mentioned any of this, and I haven't got a clue as to what we can do, so I was wondering if anyone can give me an idea or link me something. This is my first time posting, so sorry if I didn't follow a rule or something other like that.
