Science Buddies: "Ask an Expert"

hey, my project is The Effect of Artificial Sweeteners on Yeast Reproduction. The levels of my IV were 4 tbsp. of Pure Cane Sugar (C), 1 tbsp. of Splenda brand sweetener (sucralose), 1 tbsp. of Equal brand sweetener (saccharin), and 1 tbsp. of Aspartame sweetener. The amounts vary because it takes 4 tbsp. of sugar to equal the sweetening power of 1 tbsp. of Artificial Sweetener. My question is about further analyzing my data. I have 2 graphs, my formal data table, and my summary data table of the Independent Variables. I was wondering if there is any way that I could further analyze my data, to improve my project.

I was also wondering if you knew the chemical formulas for Sucralose and Saccharin, because I was not able to find a credible source for that information. (I have Googled it, Asked Jeeves, and even went to my dad )

Thank You Very Much!

Hey!

I looked up the information on formulas for you:
Sucralose - C12H19Cl3O8
Saccharin - C7H5NO3S

I'm not sure on how you would further analyze your data. I never did this experiment before, so if you tell me what your procedure is then I will be able to help you.

Have fun!

Hi Erika,

If you have made graphs showing the relationship between your independent and dependent variables, then your data analysis is probably complete. Your graphs should include a title and a description on both the x-axis and y-axis. You should go back and read the rules for your science fair and make sure you have included all of the required sections in your project. Judging is usually done on a point system, and you will lose points if an entire section is missing. One common mistake is not including a bibliography. You should make sure that your conclusion is related to the hypothesis and supported by the results. Don't just say, for example, "my hypothesis was correct." Go ahead and explain why your results do/do not support the hypothesis. Include a suggestion of what you would do differently if you were to repeat the experiment.

If there is a problem with your data and you are having a hard time making a conclusion, then let us know what your results were and we'll give you more suggestions. This sounds like it was a well designed project, and I suspect your results were clear.
