Oreo Posted December 14, 2014 Report Share Posted December 14, 2014 I am starting to think of bio ia topics, and my next one has to be about the human body (enzymes or people). I want to test heart rate,reaction time, or something similar on people. My teacher told me that my controls have to be really specific. I'm completely lost on how I could control factors like the subject's athletic ability. Any ideas? Thanks! Reply Link to post Share on other sites More sharing options...
