Day 84: Photosynthesis Lab – Light Reaction

IMG_3644

IS I students finished the photosynthesis lab. On Monday they did the dark reaction part and showed that leaves produce CO2 in the dark as they respire. Today they exposed the leaves to light and saw the CO2 levels increase in the chamber due to photosynthesis. They were able to analyze the data with Logger Pro, even determining the best linear fit and the rate of CO2 production in ppm/sec.
