Paper Chromatography-Chemical and Mechanical
Students perform paper chromatography to determine pigments in plants. In this paper chromatography lesson plan, students isolate leaf pigments, prepare a chromatogram and place their chromatogram in a solvent to separate the pigments....
Curated OER
Chromatography
Learners use chromatography to separate substances in Kool-Aid, Crayola markers and leaves. In this chromatography lesson plan, students make chromatograms to separate substances in a mixture through absorption. Learners find the Rf...

Plant Pigments
Students investigate the components of chlorophyll. They use paper chromatography to separate the many pigments of chlorophyll from one another.
Curated OER
Pigment Plucking
Young scholars examine pigments found in different fruits and vegetables and practice the processes for extracting the pigments. Pigments are used to create artwork and a class PowerPoint presentation is made on the different types of...
Curated OER
Flower Pigments
Pupils experiment with Thin Layer Chromatography to separate pigments found in flower petals.
Curated OER
Chlorophyll
Young scholars explain the importance of chlorophyll in plants. In this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take...
Curated OER
Molecular Evolution in Plants
Learners examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
Curated OER
Thin-layer chromatography
Students produce chromatograms of various vegetable extracts and standards. Using a flat bed scanner, they create a database of the results.
