Collect water samples from different sources (tap water, pond water, aquarium). Use Winkler’s method (titration with sodium thiosulfate) to determine dissolved oxygen. Calculate BOD (biological oxygen demand) by measuring DO before and after 5-day incubation. This is an excellent environmental chemistry project.
