Hi, my name is Patricia Humer. I live in Kelowna B.C. I am in grade 7 at Ecole KLO Middle School in French immersion. This is my first time going to the Canada-Wide Science Fair. I got the inspiration for my project browsing the website my science teacher recommended, Science Buddies. There I saw something about candy, chromatography and colours. Candy and colours had always interested me, but I did not know what chromatography was, so I became very interested and researched it and put my own spin on the project . For further investigation I think I would try to get a bit more information about the dyes in the M&M's (ingredients) or testing different candies. If I had to give advice to other students thinking about doing a project it would be that, you have to pick a project or topic that interests you because it is a lot more fun if you enjoy the project you are doing. My hobbies include playing soccer, sailing and Irish dance. In band I play the french horn and the trumpet. Out of school I play the piano. My dream job would be a cardiologist.

La chromatographie des bonbons
Région:Central Okanagan
Ville:Kelowna , BC
École:KLO Middle School
Sommaire:Avez-vous déjà demandé combien de colorants différents sont dans votre couleur préférée de bonbons M&M? J’ ai extracté un peu de colorant et après j’ ai utilisé chromatographie pour séparer les colorants et trouvé la réponse. Pour identifier les différents colorants j’ ai calculé le facteur de rétention de chaque colorant (la distance parcourue par le colorant / distance parcourue par le solvant)
