I. Processing and presenting data: Time (minutes) - Time (minutes) Time (minutes) - Time (minutes) Trial 1 2 Trial 3 - Average High light intensity 11.37 15.11 9.81 12.1 (Syringe A) Low light intensity 22.32 26.54 21.82 23.56 (Syringe B) Transformed data: Average of the photosynthesis rate of leaf discs under high light intensity in three trials: (11.37 +15.11 + 9.81) / 3 = 12.1 Average of the photosynthesis rate of leaf discs under low light intensity in three trials: (22.32 + 26.54 + 21.82) / 3 = 23.56 Difference between the photosynthesis rate averages of leaf discs under low light intensity and the leaf discs under high intensity : 23.56 – 12.1 = 11.46 How much shorter in times does the photosynthesis of leaf discs under high light intensity took to occur compared to the leaf discs under low light intensity? 23.56/12.1 = 1.9 times ≈ 2 times J. Conclusion: 1. Was your hypothesis supported by your results or not? Explain by describing the trends or patterns of the data and discussing the results with scientific reasoning. My hypothesis was supported by my results because all of my predictions from the beginning were quite close the final data. According to my hypothesis, I clearly stated that the higher the light intensity is, the more effect it will take on the photosynthesis rate of the leaf discs, making it process faster as the light energy excites the chlorophyll molecules. As you can see from the data table and graph, there is a specific pattern involved in the results: The amount of time it took for the leaf discs to rise up in “Syringe A” is always lower than the ones in “Syringe B” for all the three trials that were recorded. For example in average, the leaf discs in “Syringe A” took only 12.1 minutes to go pass the halfway point, while in “Syringe B”, it took 23.56 minutes for the leaf disc to reach 5cc.
