How safe are our streams, lakes, rivers and ponds? What are the pollution levels in these local surface waters? These kits allow your students to check water quality using safe, simple and effective tablet-type tests. Students will perform chlorine, dissolved oxygen, nitrate, phosphate and pH tests. Full kits also include detailed background sections on types of water pollution, sources and effects of each factor tested, color comparison charts, reproducible student handouts and a complete teacher’s guide with valuable teaching tips, answers and further extensions.
