Measuring CO2 in Air
Atmosphere and Constituents of Air
Measure CO2 levels in ambient air and exhaled air — directly teaches CO2 as constituent of air
CO2 in Exhaled Air Measurement
Importance of Oxygen
Measure CO2 increase in exhaled air — directly proves exhaled air has more CO2 (textbook experiment Fig 5.14)
Measuring CO2 Uptake During Photosynthesis
The Leaf
Measure CO2 decrease around a leaf in light — directly demonstrates photosynthesis (leaf function from textbook)
CO2 Production During Germination
The Flower
Measure CO2 released by germinating seeds — demonstrates that seeds respire during germination
CO2 in Exhaled Air
Respiratory System
Measure CO2 levels in exhaled vs inhaled air — directly proves respiration produces CO2 (textbook concept)
