Biology IA help?

Recommended Posts

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.

What ideas have you got already? We might be able to help you build on them

When 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!

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.

Hi! Okay so, we can't give you ideas, you need to come up with them then we can help you refine it.

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.

That is Chemistry, not Biology. I suggest you think about osmosis.

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.

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 :P

As long as it's an experiment that shows what you're testing for, it should be alright!
