    Chemistry stinks - class smelling activity

    This class practical introduces concepts of chemistry and smell. A number of common chemicals with distinctive smells have been chosen to help students get their nose around different functionalities in chemistry. This is done via a series of solutions, which can be smelled using smelling sticks.
