Aquatic Photosynthesis and Dissolved Gases

Students use a Wireless Optical Dissolved Oxygen sensor (PS-3246), Wireless CO₂ sensor (PS-3208), Dissolved CO₂ Waterproof Sleeve (PS-3545), and a Photosynthesis Chamber (PS-3251) to compare the metabolic products of Elodea in light and dark conditions.

This investigation can be modified to use either algae beads or an alternative leafy freshwater stem plant.

Grade Level: College • High School

Featured Equipment

Dissolved CO₂ Waterproof Sleeve

The Wireless CO₂ Sensor can be equipped for aqueous measurements using this semipermeable sleeve.

Photosynthesis Chamber

The Photosynthesis Chamber allows for fine control of water temperature and light exposure for aquatic photosynthesis experiments.

Wireless Optical Dissolved Oxygen Sensor

The redesigned small form optical dissolved oxygen sensor is compatible with all standard 12 mm probe classroom stands and stoppers.

Wireless CO₂ Sensor (Carbon Dioxide)

The Wireless CO₂ Sensor measures carbon dioxide gas levels and wirelessly streams data to your computers, tablets, and smartphones.
