a.The observation that I observe is that light source is needed for the plants to thrive and glow, the darker environment the least like it was for the plants (spinach) to grow with inthis case the would not float verse the lighter solution, they would. Which in turn the solution would be 6CO2+6H2O→C6H1206+6O26.During Part 2, what were you actually observing? Relate your answer to the process of cellular respiration; be sure to reference the equation of cellular respiration.a.The observation I made with the cellular respiration experiment was the more of a regular product use the more the cells will react. In this case, regular sugar yielded more results than other sugars used. Which in turn the solution would be C6H1206+6O2→6CO2+62H20+ATP7.For both Parts 1 & 2, identify your independent and dependent variables.a.Part 1 Independent variable are the active yeast, warm water. The dependent variable are the types of different sugarsb.Part 2 Independent variables are the baking soda, dish soap, water and spinach. The dependent variable was the light source and food coloring.
8.For both Parts 1 & 2, did anything surprise you about any of your results? Be sure to comment on what your finding are in Part 2 indicate about the use of different sweeteners in your own diet?a.What surprised in Part was how the light source really affect how photosynthesis and how with a lighter light source the spinach disk floated to the top and with a darker source they did not.b.I really liked Part 2, it was amazing to see how the different type of sugars could have an affect if the yeast would react and rise. Personally I do not use any of the sugars used in the experiment, I currently use brown sugar which is a sugar we did use in this experiment. I might give it second thought and conduct the experiment with brown sugar to see the results.
