Using a stop watch, I will measure the amount of time it takes for 5 leafs to reach the 5cc point (half way up) in each syringe and then record/compare the difference in data between the lower light intensity “A syringe” photosynthesis rate vs. the higher light intensity “B syringe” photosynthesis rate.
How to test the photosynthesis rate
Designing an experiment to test the rate of photosynthesis. Adapted from: John S Olson, Dist. 88 Schools, New Ulm, MN 56073 based on "The floating leaf disk assay for Investigating photosynthesis" Summary. This activity will allow you to measure the rate at which the photosynthesis process occurs.

Recall that rate = ∆y/∆x . Determine the initial photosynthesis rate of spinach leaf disks during the experiment and the rates between each of the time points. Record the rates in the table below. Show your calculations! Initial 0 to 5 5-10 10- 15 Overall ET50 Rates (10cm) Rates (30cm) Rates (50cm) When is the rate the highest?

As photosynthesis proceeds, the disks will start to float. At 2 minute intervals, invert the syringes to agitate the leaf disks and immediately return them to their positions in front of the lights. Count the number of disks floating after each interval until all disks are floating. ... A Measure of Photosynthetic Rate In Spinach Leaf Disks ...

Light intensity and the rate of photosynthesis. Students’ Sheet. ... Turn out the lab lights and measure the light intensity of each point on the grid and record the values in your results table. Light intensity can be measured using a light sensor attached to a data logger, or using a light meter app on a smart phone (there are plenty of ...
