- light intensity. Dependent variable: - concentration of dissolved oxygen in water sample. Controlled variable: - water temperature - room temperature - humidity. The experiment bottles are exposed to several different light intensities. This will be done using the reflector at five different distances (range from 20 – 100 cm).

Influence of Light Intensity on Rate of Photosynthesis (Adapted from Perry and Morton (1995) Laboratory Manual) As a class, we will evaluate the influence of light intensity on the rate of photosynthesis by testing three different light intensities: 25W, 75W, and 200 W. Each group will be assigned one light intensity to test.

In (c) most students appreciated that in dim light photosynthesis and respiration would both occur and there would be no change in the carbon dioxide concentration in the tube. In part (d) students were asked about another experiment to investigate the effect of light intensity on photosynthesis in a water plant.

The equation for photosynthesis is as follows: Light. 6CO2 + 6H2O ( C6H12O6 + 6O2. One of the products of photosynthesis is C6H12O6, which represents a molecule of glucose. As the plant receives sunlight it is constantly producing glucose and then transporting it outside of the chloroplast. ... Lab Experiment on Light and Starch Production in ...

We have found, for example, that the rate of photosynthesis in the presence of 4 layers of Filter 298 is the same as that found in the presence of one layer of Filter 210. Clearly, other combinations are possible. Science & Plants for Schools: www.saps.org.uk. The effect of light colour and intensity on the rate of photosynthesis: p. 1

Thus far we have investigated the increase in the rate of photosynthesis as a function of light intensity. However, from our spectral analysis it is clear that wavelength of incident radiation will also effect photosynthetic rate. In this experiment we will estimate the photosynthetic rate by measuring the rate of oxygen production of the plant.
