Overview: In this laboratory, students measure the rate of photosynthesis under various light conditions using small disks cut from plant leaves and a vacuum syringe. This lab can be easily expanded to include student-centered investigations.
Curriculum Connections: photosynthesis, cellular respiration, enzymes, plants, nutrient cycling
Experimental Timing: From start to finish this lab can be completed in a single 45-50 minute class period. For additional information, see "Instructor Planning Guide" in the Teacher Materials.
Specialized Equipment Required: fluorescent light bulbs (15 watt) • 10 mL syringes
