So I'm trying to come up with a topic for my SL math IA and I'm currently working with the idea of modelling the population decrease of nesting leatherback sea turtles in Las Baulas. I plan on creating an equation to predict the further decrease of the population if humans do not intervene, and possibly seeing what type of graph this population matches. The only issue is I can't decide if it is more of a science IA or a math IA. Any thoughts??
