KimberlyDorffner Posted December 13, 2012 Report Share Posted December 13, 2012 I have a few ideas, very few ideas, of what I can do with my IA. My IA needs to have something to do with water, and I was wondering if anyone could help me. I just need a brief idea, not the entire IA. My teacher says she'll provide us with any necessary equipment. 1 Reply Link to post Share on other sites More sharing options...
khimberleigh Posted December 13, 2012 Report Share Posted December 13, 2012 What ideas have you got already? We might be able to help you build on themWhen I do science IAs I use this basic model: How does___________affect__________. Fill in the blanks and you've got yourself a topic!If that doesn't help, think of any equations you know to do with water. Then just make one of the variables you independent variable and one your dependent.I know I'm being a bit vague but that's because we can't actually give you a topic because you get assessed on it. However, as I said before, we can help improve any ideas you may already have.Good Luck! Reply Link to post Share on other sites More sharing options...
KimberlyDorffner Posted December 13, 2012 Author Report Share Posted December 13, 2012 (edited) I want to do how salt affects its cohesive property (the difference between salt water and distilled) but I feel that is too simple and I don't even know how to test that.

Has your teacher not given you a guideline? Our teacher used to give us a question and we had to figure out a lab by ourselves. If not, I say flip through your text book (that's what I used to do) and see if it can give you any ideas. Reply Link to post Share on other sites More sharing options...
Sandwich Posted December 13, 2012 Report Share Posted December 13, 2012 I want to do how salt affects its cohesive property (the difference between salt water and distilled) but I feel that is too simple and I don't even know how to test that.That is Chemistry, not Biology. I suggest you think about osmosis. Reply Link to post Share on other sites More sharing options...
KimberlyDorffner Posted December 13, 2012 Author Report Share Posted December 13, 2012 Our teacher said it had to have something to do with water's properties, so I kind of just took a shot in the dark there. But thanks, osmosis sounds like a much better idea. Reply Link to post Share on other sites More sharing options...
kim luffy Posted December 14, 2012 Report Share Posted December 14, 2012 If you're going to do it on osmosis. You could do it on potatoes. Like, put a bunch of potatoes in water and the another bunch in water with salt. Measure them before and after etc etc. That could probably be better. 1 Reply Link to post Share on other sites More sharing options...
KimberlyDorffner Posted December 14, 2012 Author Report Share Posted December 14, 2012 Hmm, I think that's a really good idea, but it doesn't seem very...original. Can you lose points for that? Reply Link to post Share on other sites More sharing options...
khimberleigh Posted December 14, 2012 Report Share Posted December 14, 2012 No, most if not all experiments you do will have been done before, and it doesn't matter how basic your experiment is either you won't lose points. Reply Link to post Share on other sites More sharing options...
kim luffy Posted December 14, 2012 Report Share Posted December 14, 2012 What khimberleigh said. You won't lose points for that. If that were the case, most people would fail the IA's in Biology for them not being so original As long as it's an experiment that shows what you're testing for, it should be alright!
