I need to come up with a few ideas for science fair, but I'm drawing a blank. I'm interested in nutrition, and so far I have: Which citrus fruit (out of lime, lemon, orange, tangerine and grapefruit) provides the greatest quantity of vitamin c? This is high school science fair for honors students, and last year I competed at the state level, so no "baking soda volcanos". This science fair is pretty extreme (in other words, up until 2 am from now until january), so I need generally advanced topics. Any suggestions?
