Ok, so I need some ideas for my science fair project.

Hm...I don't know about that...Wait, isn't that the place where red blood cells are produced?
We did an experiment that drained calcium from bones. Are they somehow related?

Hmm...Well, that would be kinda difficult, seeing that we'd have to go get a piece of chicken bone...

Well, thanks anyway. You guys are really appreciated.

try this. Test what liquids/foods are most damaging to your bones. It's like teeth.

So put a bone in milk, a bone in water in water (as a control, or make two waters: one hopefully distilled/bottled, and one tap water), in vinegar, in soda, in orange juice...etc

The bones will start to loose their rigidness and will be able to bend. You can bend them each day, and use a protracter to measure the degrees of the angle of the bend. So after a few days (I hope at least a week), check which liquid was the most harmful to your bones.

(Use chicken bones. Chicken leg bones.)

Then explain why this happened.

Good luck!

Did you actually perform it? Just wondering, and wondering what results you got. (Though I have a set of results in my head, I want to see how it compared to yours.)
