    Biology IA

    I would like to do an IA on the effect of antacids on neutralizing stomach acid, using diluted HCl, but I've been told it's siding more towards Chemistry. Are there any ways that I could make this more of a biology related IA, and how can I do so? Someone told me to involve an enzyme, like pepsin, but I'm not sure of what to do with it. Thanks!
  2. Hi! I just wanted to pop in and ask out of curiosty -- how would you perform the IA as a biology one? How can I get pepsin? And how would the experiment go?
