Young scholars perform paper chromatography to determine pigments in plants. For this paper chromatography lesson plan, students isolate leaf pigments, prepare a chromatogram and place their chromatogram in a solvent to separate the...

Young scholars identify the colors in leaves. For this chromatography lesson, students read the book Why Do Leaves Change Color? and construct chromatography strips to identify the colors of leaves.

Students explain the importance of chlorophyll in plants. For this biology lesson, students extract chlorophyll from different plant sources using chromatography. They discover the different factors needed for photosynthesis to take place.

Young scholars explore the process of photosynthesis by identifying chloroplasts and chlorophyll pigments. In a demonstration, they observe a demonstration connecting pigments with sunlight conversion into energy. Using paper...
