Juan Fernando Muñoz Arenas Posted February 7, 2017 Report Share Posted February 7, 2017 (edited) Hello, I'm currently working on my Bio IA (standard level) and need some help brainstorming some good ideas. I have two ideas... - Comparison of the rate of germination between different bean seeds that have been exposed to different types of fertilizers. - Look at how much time it takes for bacteria to contaminate food when it’s dropped in order to prove the 5 second rule. Either feedback on my current ideas or new ideas are welcomed!!! Thanks!!! Edited February 7, 2017 by Juan Fernando Muñoz Arenas Reply Link to post Share on other sites More sharing options...
