AT b/ AT h students could – use three-way taps, manometers and simple respirometers to measure volumes of air involved in gas exchange AO1 development of – knowledge of mechanism of breathing and associated measurements and the techniques associated with spirometers and respirometers PS 3.1/AO3/AO2 interpret – graphs showing spirometer traces. Extension Students conduct a practical to measure volume of air being breathed in eg spirometers or respirometers with manometer tube, scale and three-way tap. They plot their data and then discuss how to interpret the spirometer traces to identify tidal volumes.
