Leaf chromatography
In association with Nuffield Foundation
Investigate leaves using paper chromatography with this classroom experiment and follow-up questions
In this practical, learners carry out paper chromatography to find the pigments present in leaves. The downloadable resources include two levels of student worksheet (scaffolded and unscaffolded) with practical method and follow-up questions. Learners will calculate Rf values, identify different phases in paper chromatography and build confidence describing and explaining the process. Lesson slides, technician and teacher notes containing answers to the questions on the student worksheets are also included.
