On considering my experiment, in hindsight, perhaps I would have
gained an even higher rate of photosynthesis if I had made the
temperature of the water slightly lower.
Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.
We can measure the rate of photosynthesis such as Canadian pondweed.
Measuring the rate of photosynthesis a full protocol on how to investigate photosynthesis using pondweed.
There is an optimum temperature at which the rate of photosynthesis is maximum.
A suitable experiment for GCSE to determine whether incident light intensity affects the photosynthesis rathe in the pondweed elodea.
This activity is a lab where students design an experiment to test the rate of photosynthesis.
Oxygen bubbles are given off by the plant in response to photosynthesis.
This experiment will look at the affect of light intensity on the rate of photosynthesis on Elodea plants.
Investigate The Influence Of Carbon Dioxide On The Rate Of Photosynthesis Biology – Leaving Cert Experiments.
In this practical experiment, the rate of photosynthesis is measured by counting the number of bubbles rising from the cut end of a piece of Cabomba pondweed.
When the temperature rises the rate of photosynthesis rises also.
is repeated over the duration of the experiment.
The rate of photosynthesis in Elodea can be indirectly measured by observing the amount of oxygen bubbles given off by the leaves.
Factors affecting the rate of photosynthesis.
Plants make their own food – absorbing and converting sunlight energy into chemical energy stored in carbohydrates such as glucose and other.
Using the rate of oxygen production in pondweed (Elodea and Cabomba) in an experiment to demonstrate the rate of photosynthesis.
Duration: 45 min Class Size: Up to 32 students General Overview: In this lab, students will make hypotheses about.
Experiments to show the factors required in photosynthesis (2) - light and carbon dioxide.
Demonstrating oxygen evolution during photosynthesis using Cabomba pondweed the rate of bubbling can serve as an indication of the rate of photosynthesis.
6CO + 6H O = C H O + 6O The factors that effect the rate of photosynthisis are the amount of light, the amount of carbon-dioxide (CO ) and the temperature that can be used by the plant....
By adjusting the
levels of carbon dioxide available to the plant I could still measure
whether this affects the rate of photosynthesis in pondweed.
on how different limiting factors affect the rate of photosynthesis.

If I had altered the water steadily by 1
degree, instead of making it 25 degrees C straight away, I may have
found that the water only needed to be at 22 or 23 degrees, and the
pond weed would have photosynthesised at a higher rate at this
20 degrees centigrade is the
recommended temperature for photosynthesis, and yet we conducted out
experiment with the water around 25-27 degrees C, as I found that 20
degrees was a little low.
6CO + 6H O ® C H O + 12O (in the presence of light energy and chlorophyll) Aim- The aim of the experiment is to determine what effect light intensity has upon the rate of photosynthesis of Canadian Pondweed (Elodea)....

Results obtained from experiment : "Investigating if light intensity
effects the rate of photosynthesis in an aquatic plant."
As mentioned previously, the results I have obtained from the
experiment will be of measured in 5 intervals, ranging from 0cm
-100cm, 1 repeat reading taken as well as an original reading & an
average of the 2 results calculated.
