Figuring out what you are interested in

Think about what environmental contaminants are of concern to you. For instance, lead, crude oil, PAH - polyaromatic hydrocarbons, e. coli bacteria, and many others.

Consider whether these contaminants are elements, molecules, biological, other? Having an idea of the nature of these contaminants will help you conceptualize during this activity.

Collecting known reference samples

Think about where you could get a sample of these contaminants

Get ahold of a clean glass container, perhaps even order sterile glass container to avoid soap residue. One with flat sides and bottom will make it easier to shine light through.
