Using CO2 probes in the classroom - The SSERC Team
Aims Introduce CO2 probes - Cell respiration - Temperature / respiration - Sugars / respiration (not being done) - Photosynthesis / respiration SSERC support
CO2 probes Based on: Delpech, R. (2006): Making the invisible visible: monitoring levels of gaseous carbon dioxide in the field and classroom School Science Review, 87 (320), 41-51. CO2 probes
