Classroom Leaf Disk Photosynthesis Kit | AP Biology

AP® Biology Investigation #5: A Photosynthesis Kit from Innovating Science

This Classroom Leaf Disk Photosynthesis Kit contains the necessary components, and detailed instructions, to take students through the popular leaf disk photosynthesis demonstration.

In this lab, students will use leaf disks to measure the accumulation of oxygen and relate it to the rate of photosynthesis. They will use guided inquiry to explore the impact of different variables on the photosynthetic rate, and they will learn about the necessary aspects and conditions for photosynthesis to occur. 

This photosynthesis lab kit includes a detailed teacher's manual, reproducible student worksheets, and materials sufficient for 8 lab groups. This lab meets AP Science Practices 1, 2, 3, 6, and 7, and Big Idea 2.
