Students examine specific skills in assessing water quality from a holistic approach. They assess the health of a local watershed and identify problems in the local watershed and suggest remediation.

A thorough background and nitrate sampling lab sheet are provided to share with your young scientists. After discussing the nitrogen cycle with the class, you will break them into small groups and show them how to use their inquiry...

The difference between accuracy and precision is fundamental for high school science learners. Using test kits for nitrate concentration in water, they compare readings with each other. They consider the accuracy, precision, and bias of...

Students determine the effects of an increase of the amount of nitrate and phosphate levels on the growth of algae. the development of a hypothesis is encouraged and students proceed to a conclusion based on their results.

Students examine the effects of nitrates and phosphates on the dissolved oxygen levels in different water sources. In this series of 3 lessons, they consider the reasons for nitrate and phosphate level increases and their effects on...

Discusses the chemistry of nitrate, the negative agricultural effects of too much nitrate in soil and in water sources, its toxicity to plants and livestock, and the impact on human health.

In this inquiry, students engage with mapping data to determine what kind of land coverage is contributing the most to harmful algal blooms in the Chesapeake Bay Watershed. Click on the link for teacher resources for teaching guides and...
