Biology pondweed experiment
WebPondweed Simulation. Introduction: In this simulation, you will be looking at the production of oxygen as a plant photosynthesizes. This procedure can be accomplished by placing elodea plants in water with baking soda to provide carbon. The plant can. then be exposed to varying intensities and colors of light. WebIn this experiment a 100 Watt bulb was used. As the bulb emits light in all direction we use the area of a sphere with the radius being the distance from the pond weed. The number of bubbles given off in a minute is taken as the rate of photosynthesis and plotted against the calculated light intensity.
