Question

Now that the lab is complete, it is time to write your lab report. The purpose of this guide is to help you write a clear and concise report that summarizes the lab you have just completed. 
The lab report is composed of two sections:
Section I: Overview of Investigation 					
Provide background information.
Summarize the procedure.

Section II: Observations and Conclusions					
Include any charts, tables, or drawings required by your teacher.
Include answers to follow-up questions.
Explain how the investigation could be improved.

To help you write your lab report, you will first answer the four questions listed below based on the lab that you have just completed. Then you will use the answers to these questions to write the lab report that you will turn in to your teacher. 
You can upload your completed report with the upload tool in formats such as OpenOffice.org, Microsoft Word, or PDF. Alternatively, your teacher may ask you to turn in a paper copy of your report or use a web-based writing tool.

### Lab Report #### Section I: Overview of Investigation The purpose of this lab was to investigate the effect of different light conditions on the rate of photosynthesis in aquatic plants, specifically Elodea. Understanding how light intensity influences photosynthesis is crucial for comprehending plant growth and ecosystem dynamics. The primary objective was to determine the correlation between varying light levels and the amount of oxygen produced by the plant, which serves as a proxy for photosynthetic activity. To carry out the experiment, we first set up several beakers filled with equal amounts of water and Elodea cuttings. We then placed each beaker at different distances from a light source, creating varying light intensities. Over a set time period, we observed the rate of oxygen production, which was indicated by the number of oxygen bubbles released from the plant. After taking measurements at each distance, we compiled the data and analyzed it to draw conclusions about the relationship between light intensity and photosynthesis. #### Section II: Observations and Conclusions To effectively summarize our findings, I created a table titled "Effects of Light Intensity on Photosynthesis Rate," which includes columns for the distance of the beaker from the light source, the estimated light intensity, and the average number of bubbles produced per minute. Each column is appropriately labeled to reflect the relevant information, providing a clear and concise representation of the collected data. | Distance from Light Source (cm) | Estimated Light Intensity (lux) | Average Bubbles per Minute | |-----------------------------------|----------------------------------|----------------------------| | 10 | 1000 | 30 | | 20 | 500 | 20 | | 30 | 250 | 10 | | 40 | 100 | 5 | If I could repeat the lab, I would consider using a more precise method to measure light intensity rather than relying on estimated values. Additionally, I could increase the duration of the experiment to gather more data, allowing for a better understanding of any long-term trends in photosynthesis across various light conditions. These changes would help refine the results and enhance the overall accuracy of the conclusions drawn from the investigation. In conclusion, this lab provided valuable insight into the influence of light on photosynthesis, revealing trends that underscore the importance of light availability for plant growth and productivity.
