Dissolved Oxygen and Photosynthesis
Students will know that plants produce oxygen underwater and be able to design an experiment that will test this question.
Grade Level: 2 class periods
Time Required: Cornelia Harris- Cary Institute. This lesson is part of the Changing Hudson Project curriculum.

Updated in April 2024! This presentation goes deeper into river parameters with HRECOS. By using case studies and curated HRECOS graphs, students can investigate weather, water chemistry, and biological phenomena. Notes for each slide provide background content and instructions for teachers.

Wading into the Hudson is an introduction to the Hudson River estuary essentials, including tides, currents, salinity, and climate change. And it’s all taught through interpreting graphs and images. Slides include notes and instructions for teachers.
Students will:
- Understand the critical role of dissolved oxygen in supporting aquatic life;
- Observe and graph dissolved oxygen concentrations at sites along the Hudson River estuary;
- Observe patterns of change in dissolved oxygen concentrations;
- Identify environmental parameters correlated with dissolved oxygen concentrations;
- Suggest hypotheses to account for the observed changes in dissolved oxygen concentrations.
