Floating Disks: Investigating Photosynthesis

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
