Lab-Aids: Pollutant Effects of Phosphates and Nitrates - Bilingual English/Spanish
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 the blooming of algae and bacteria.
Investigate pollution and environmental impact
Experiment with phosphate and nitrate compounds and the growth of algae over a 10 day period
