Science Buddies: "Ask an Expert"

I am doing my science project on flower pigment chromatography. I am going to compare 3 colors of 3 different types of flowers using the paper chromatography and the thin layer plate method ( I am going to make my own using cornstarch&water). At first I was going to use as a problem: Do different flower species use the same pigment molocules, but now I am wondering if I should use a different problem. Any suggestions?

Hi!
I think your project sounds great!

The molecules are of the same kind essentially, although, of course, you will get pigments will slightly different colors and patterns, etc. Good luck!
