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?

If you have access to a liquid chromatograph and can squeeze beaucoup lemon, lime, orange, tangerine, and grapefruit juice, maybe. Alternatively, you might do the same with paper chromatography. You would have to have a reagent that develops the vitamin C spot preferentially. You'd have to get longer strips of filter paper than can be cut from coffee machine filters. And you need development containers. Intermediate in expense might be thin-layer chromatography. You'd have to buy the thin-layer plates from a supply house.

hi Nectarine. you will possibly be able to evaluate comparing the diet c status of organic and organic as against non-organic and organic culmination. This has been executed for oranges, with the looking that diet c content textile in organic and organic oranges is significantly better than 'prevalent' oranges. the better value of organic and organic produce may be justified by way of the better nutrient content textile (extra bang for the dollar!). additionally, study point out that fifty% of human beings eat under the RDI for diet C, so it is an substantial wellbeing subject. superb desires and sturdy good fortune.
