Vernier Lab Part II
• Determine whether germinated or non-germinated peas respire.
• Use a CO2 gas sensor to measure concentrations of carbon dioxide.
• Study the effect of temperature on cell respiration.
• Compare the rates of cell respirations in germinated peas and non-germinated peas.
Materials
• CO2 sensor• 250mL respiration chamber Computer• Logger pro software• Lab pro (sensor-computer interface)• 25 germinating peas• 25 non-germinating peas• Thermometer
Extensions
• Measure O2 concentration using germinated and non germinating peas at different temperatures
• Measure pressure changes during respiration of germinating and non-germinating peas at different temperatures (AP Biology lab)
• Simultaneously measure O2 and CO2 concentrations at different temperatures for germinating and non-germinating peas.
