    My RQ is "Is there an effect of carbonated beverages on the number of lactobacillus.casei and bifidobacterium.animalis found in human digestive tract?” I am taking two beverages, coke and sprite. First I will culture them, and then test them to different concentrations to coke and sprite. The methodology is very time consuming as it involves sterilizing and waiting for the culture to grow etc.

    And after that, I will do graphs, statistical tests etc.
    Is this sufficient in terms of the variables and the amount of experimentation?

    Thanks a lot!

    I think your bigger question is will you have the time and resources to do this? Have you discussed it with your tutor?
