ABOUT THIS PRODUCT:


**FREE KIT RESOURCE**

Although phosphorus is an element that is essential in many aspects of daily life, excess of the element can negatively affect ecosystems. In this FREE lesson, students will measure phosphate concentration in water samples. By comparing their results to environmental safety guidelines, students will connect how nutrient levels connect to ecosystem health.

• Use simple colorimetric methods to detect and measure phosphorous levels in real or simulated water samples.
• Explore how fertilizer runoff contributes to eutrophication and related health concerns.
• Interpret experimental results and propose solutions to reduce nutrient pollution.
• This project was made possible by a Science Education Partnership Award (SEPA), Grant Number 2R44GM143977-02, from the National Institute of General Medical Sciences (NIGMS) of the National Institutes of Health (NIH).
