From Field to Flask: Investigating Nitrogen’s Impact on Waterways - Edvotek 928 Module VII: 15 minsNitrogen is essential for all life on Earth its a key part of DNA, proteins, and the food we eat. 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. Use simple colorimetric methods to detect and measure nitrate levels in real or
