Dissolved Oxygen Investigations
Explore Biology, Environmental Science, and Chemistry concepts while using the Wireless Optical Dissolved Oxygen sensor and the Photosynthesis Chamber to measure oxygen in solutions.
Grade Level: Advanced Placement • High School
Subject: Biology • Chemistry • Environmental Science
Activities
01) What Factors Affect Dissolved Oxygen?
Students will use a dissolved oxygen sensor to determine how different factors affect the concentration of dissolved oxygen in water.
02) Enzyme Action (Optical Dissolved Oxygen)
Students use a Wireless Optical Dissolved Oxygen (ODO) sensor and (optional) Photosynthesis Chamber to compare the rate of hydrogen peroxide decomposition with and without a catalyst.
03) Photosynthesis and Respiration with Algae Beads
Students use a Wireless Optical Dissolved Oxygen Sensor (PS-3246) and a Photosynthesis Chamber (SE-3251) to compare the metabolism of algae beads in light and dark conditions.
04) Cellular Respiration in Yeast (Optical Dissolved Oxygen)
Students use a Wireless Optical Dissolved Oxygen sensor and a Photosynthesis Chamber to investigate the effect of temperature on the cellular respiration rate of yeast cells.
05) Blockly Extension: Fish Tank Water Quality
Students will use an optical dissolved oxygen sensor and Blockly code to write a program that helps children understand the relationship between the amount of oxygen dissolved in fish tank water and the comfort level of a freshwater fish.
