In my hypothesis I did not predict anything that was wrong, however, I did miss out a few things. Above is a lab that I did in science class about photosynthesis. Once this happens the plant will start to only take in the heat from the light, which could in the long run be bad for the plant, and the process of photosynthesis.
My graph had not completely plateaued yet however I predict that by about Waterweed sim to 16 lux the graph would have plateaued and would have became a horizontal line, because the waterweed only needs a certain amount of light to photosynthesize and once it gets that much light, the amount of oxygen bubbles produced will not decrease neither will they increase.
It is shown because the amount of oxygen bubbles produced by the waterweed increased as the lux of the light intensity increased. My hypothesis was somewhat correct because in the hypothesis I wrote that as the amount of light emitted increased the amount of oxygen Waterweed sim produced would also increase.
Another issue that my method had was the accuracy of the measuring of the oxygen released. So if we had decreased the light intensity then the data tables, and graphs would show that as the light intensity decreased so did the number of oxygen bubbles. My data shows that light is one of the many limiting factors in the process of photosynthesis alongside water, soil, carbon dioxide, etc.
I think that my hypothesis was valid because I predicted based on my prior knowledge on the subject and I supported my hypothesis with scientific reasoning. When the plant photosynthesizes it releases bubbles of oxygen, however, the size of those bubbles is unknown so some bubbles could be larger than others.
To measure the volume of the oxygen solely, I could use a gas syringe, which would allow me to be as accurate as I could when it comes to measuring the oxygen released. This is because the plant can only take in so much light.
Since the chlorophyll is vital for the process of photosynthesis because it takes in the light energy from the sun which is used for photosynthesis it being damaged eventually kills the plant.
A possible improvement to this could be that I could have been to covered the container with the waterweed and the water with cling film because if I cover the container with cling film the water that would evaporate would stick to the cling film and then eventually condensate and turn from water vapor back to its liquid form.
Evaluation The method that I wrote for this experiment is valid because it accomplishes the aim of my experiment, which was to see how light intensity affected the number of oxygen bubbles produced from a waterweed.
It was a fair test because all my controlled variables stayed controlled and did not fluctuate throughout the experiment and I went to a great extent to control all of my variables, which again reinstates the fact that I have accomplished the aim mentioned at the beginning of the experiment.
The light, being a limiting factor, is very important for the process of photosynthesis and harshly affects how quickly the plant inhales carbon dioxide and exhales oxygen. Possibly the most significant issue that my method had was the evaporation of water.
Too much heat from the light for a long period of time will start Waterweed sim dry out the leaves of the plant and will start to damage the chlorophyll. This happens because after too much intensity the light will lose its effect on the plant. So to conclude too much light intensity is not harmful to the plant if the light intensity is that strong for a short period of time, however, when it is like that for a long time it can kill the plant.
My method fulfills the aim because it had enough information to answer my aim as it answered how my independent variable, which was the light intensity, affected by dependent variable, which was the number of oxygen bubbles that the waterweed released.
My data shows that as the the light intensity increased the amount of bubbles produced did increase however only to a certain point, and I did not state this in my hypothesis.
This happened because the waterweed only needed a certain amount of light to photosynthesize. My results show that as the light intensity increases the amount of oxygen bubbles produced also increase, this is evident through my positively correlated graph, however, the graph also shows that by the time it got to 8 lux the graph started to plateau.
I think that my method is very reliable because it was a fair test.Waterweed Simulator I do not know the original source of killarney10mile.com file, and I have been unable to locate its original owner.
This simulator can be used with the Waterweed Simulation Worksheet. Photosynthesis Summative Lab-Waterweed Simulation Research Question: The aim of this experiment is to investigate how the light intensity (lux) affects the number of oxygen bubbles produced when a weed is placed into water and tested for a controlled time period of 30 seconds (in the simulation).
Water Weed Simulation 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.

Waterweed Simulation of Photosynthesis: Lab #_____ 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. 4. Based on the simulation experiments, what factors can affect the rate of photosynthesis in a plant?
