Students make simple respirometers to create a respiration chamber to study cellular respiration. The amount of oxygen consumed by germinating and nongerminating pea seeds is measured and compared to changes in the control (glass beads). The effect of cold on cellular respiration is also investigated.Enough materials needed to assemble six respirometers per group. 18"x 13"x 2.5 pans and thermometers are required but not included in the kit.
