Resource produced to visually illustrate how a mixture is separated into pure substances during chromatography. Designed initially for a low ability year 9 group (2017 Edexcel GCSE Combined Science).

Students use different colours to show particles present in ink and dies involved in chromatography; then identify mixture / pure substances and calculate Rf values.
