Suggested Experiments
- Monitor human respiration during exercise
- Measure concentration of oxygen gas generated during decomposition of hydrogen peroxide by catalase
- Monitor changes in oxygen concentration during photosynthesis and respiration of plants
- Monitor respiration of animals, insects, or germinating seeds
- Monitor oxidation of metals such as iron
- Monitor consumption of oxygen by yeast during respiration of sugars
- Investigate respired oxygen levels while a student holds his or her breath for different time intervals
Monitoring O2 levels afterholding breath
