Does anyone know about the IB Diploma course? We're supposed to make a project or investigation and analyze the physics, chemistry and biology aspect of it... the theme of the project is 'Go Green' and it can be literal (do things involving green things, paint green stuff)... I'm confused of what project should my group do (my group consists of 3 people). We were planning on focusing on energy efficiency or clean energy source, and we wanted to investigate manure or feces as an energy source... but I don't think anyone would do that. Can anyone give an example of a topic that involves physics, chemistry and biology?
