These are links to a whole lot of prac write ups which include videos of the pracs being performed. Might be handy for those of you who (like myself) have either missed pracs or not payed attention. Hope it helps:

Testing for reducing sugars using Fehling's solution
Biuret reaction - protein in egg
Separation of Food Dyes by Thin Layer Chromatography (TLC)
Separation of Lipohilic Dyes by Thin Layer Chromatography
Separation of Plant Pigments by Thin Layer Chromatography
Separation of Plant Pigments by Column Chromatography
Starch test
