Edvotek® From Field To Flask: Investigating Nitrogen's Impact On Waterways

Water quality analysis and public planning.

• Use colorimetric methods to measure nitrate levels Explore how fertilizer runoff contributes to eutrophication Interpret nitrate results and propose solutions

In this experiment, students will explore sources of nitrogen in our environment by testing samples for nitrates and nitrites using the Griess reagent. Students will create a standard curve to calculate the concentrations of samples with unknown amounts of nitrate and nitrite.

Ordering information: You need: Micropipettes and tips, spectrophotometer, water bath PPE, distilled water and assorted laboratory glassware. Computer with spreadsheet software highly recommended.

Delivery information: Includes instructions, nitrate and nitrite solutions, Griess indicator solution components, conical tubes, microcentrifuge tubes, and PCR tubes.
