ibstudent77 Posted October 14, 2015 Report Share Posted October 14, 2015 Hey guys! I'm planning to do my Biology IA on how different wavelengths of light affect the rate of photosynthesis. My RQ would be: How do different wavelengths of light affect the rate of photosynthesis in Cabomba Carolinesis? I'd use red, green, blue, and orange. I have 2 questions: 1. Is this IA idea too simple? Is there anything that can lend an element of complexity to it?2. For the controlled, should I use white or yellow light? Please respond ASAP as my previous experiments have failed and I'm starting to panic! 1 Reply Link to post Share on other sites More sharing options...
IBsurvivor98 Posted October 14, 2015 Report Share Posted October 14, 2015 Hey buddy! I recommend that you ask your bio departmental head as they will probably have a better idea of the needs of your experiment. Let me know how it goes! Reply Link to post Share on other sites More sharing options...
MuskanKararha Posted October 16, 2015 Report Share Posted October 16, 2015 Hey! So if your teacher is as strict as mine, she will tell you that a third grader can do that IA and it's more like ESS than Biology, but if your teacher is okay with that topic, I think the best thing you can do for yourself is to keep it simple. For the control you should use white light, because sunlight is basically white light. Good luck Reply Link to post Share on other sites More sharing options...
