Pollutant Effects of Phosphates and Nitrates

Description

This kit is an excellent environmental pollution laboratory activity. Students use water samples from nearby fresh waterways to set up controlled experiments, observe them, and determine the effects on fresh water (both qualitative and quantitative) when phosphate and nitrate compounds are added. Over a period of ten days, students will observe and compare the blooming of algae and bacteria in water samples spiked with varying amounts of pollutants.
