Water Contaminant Science

~60 min · 15 stations

Water Contaminant Science is a self-paced learning path in Chemistry & Molecular Science, free to read, written at General Public / 9th Grade reading level. Across 15 structured stations, you will work through the core ideas step by step, each with a short quiz to check your understanding. By the end you will be able to define aqueous solutions through molecular interactions; categorize common types of water impurities; explain how polarity dictates substance dissolution.
