The lesson plan is about teaching 9th standard students about chromatography through discussion and experiments. It involves observing how ink, a mixture of many colors, separates into its different color components when placed on a filter paper. Students will see for themselves how chromatography works to separate mixtures and will learn that it uses the principle of different substances traveling at different rates through a solvent. They will develop an understanding of chromatography and mixtures.
