Jun 10, 2025 · With baking soda and spinach leaf disks, it's easy to create a photosynthesis demonstration that shows off this natural process.

At any given point in this experiment, the number of floating leaf disks is an indirect measurement of the net rate of photosynthesis. In photosynthesis, plants use energy from the sun, water, and carbon …

In this fun plant biology project, you will explore how plants use photosynthesis to make energy for themselves with the help of the floating leaf disk assay.

This video demonstrates the photosynthesis lab using floating spinach disks. The disks are deoxygenated and then exposed to two different solutions.

In this lab, you will be using leaf disks, to assay the net rate of photosynthesis under various lighting conditions. Leaf disks normally float, however if you remove the air from the air spaces, the overall …

In this lab, students explore the process of photosynthesis in spinach leaves. As oxygen is produced, the density of the leaves change and they will begin floating in a sodium bicarbonate solution. The time it …

Over the years, I have found the floating leaf disk assay technique to be reliable and understandable to students. Once the students are familiar with the technique they can readily design experiments to …

Students can hypothesize whether the presence of baking soda and light will increase, decrease, or have no effect on the rate of photosynthesis in spinach leaf disks.

Design an experiment using the floating disk assay to investigate the effect of different wavelengths of light on the rate of photosynthesis. Be sure your experiment includes the following:
