Hi fellow IB students, I reaallyyy need you help!! I was told today that my BIO IA is too easy to be an IB IA. My project is on weather different concentration of soap better eliminate or kill bacteria found on our hands. Since it was too easy we started talking about changing my project to finding out how long does it take for bacteria to be eliminate on a wet rag put in a microwave (it is known that that method eliminates bacteria). However since that study has been done before I would have to add another factor... We thought about putting it in a microwave where we can adjust the
