Created by an IB Assistant Examiner, this Guided Experiment / Lab Guide includes everything you and your students need for completing the IB Required Practical 4: Chromatography (Separation of photosynthetic pigments by chromatograph).
IBDP Biology Teachers can use this Guided Investigation to support students as they:
Organise the equipment and materials needed to separate plant photosynthetic pigments.
Conduct a plant chromatography experiment to produce a chromatogram.
Use their chromatogram to calculate the retardation factor for each pigment (Rf).
Use the calculated Rf factor and the included table to identify the pigments in the leaves of the plant.
Also suitable for other curriculum programs - any kind of High School Biology course that focuses on scientific inquiry, such as AP Biology or Honors Biology.
Skill (from IB Biology Guide):
Separation of photosynthetic pigments by chromatograph.
This Guided Lab Investigation has everything you need to prepare your IB SL and HL students to be ready to answer the many plant chromatography questions on the IBDP Biology Examination.

IB Biology Required Practicals Student Guides
Created by an IB Assistant Examiner, this 58 page BUNDLE of Required Practical Lab Guides provides full instructions for completing the IB Bio Required Practicals 1-7, with everything students need to complete the experiments, write their lab reports, and to practice the skills required for writing their Higher Level and Standard Level Internal Assessments (IB Biology SL and HL IAs). IBDP Biology teachers can use this Required Practical bundle to assign their HL and SL students the IB Diploma Biology required practicals, as students are guided through the laboratory experiments and the writing of scientific investigations (lab reports) which meet the IB DP Assessment Criteria: Exploration, Analysis, Evaluation, and Communication. These experiment guides have everything you need for your students to be successful completing their practice IB Bio Internal Assessments (IAs). No other resources are required (other than laboratory materials and equipment). Every year, Paper 3 Section 1 of the IB Biology Exam has included questions on these Required Practicals. These practice investigations (lab guides) would also be suitable for any other High School Biology curriculum with a focus on scientific investigation and experiment lab report writing, such as Honors Biology or AP Biology. Features: Links to IB Assessment Criteria and Rubrics Key Terms Organised with clear subheadings (using IB Assessment Criteria) Easy to Follow Set-up suggestions based on IB Bio classroom experience Tips for success with IB Biology Internal Assessment Bullet Points and diagrams for clarity Sample data tables Clear Instructions for writing a lab report (scientific investigation) List of related IB Exam question numbers from past papers Save yourself time - don't recreate the wheel. Ready to use as-is with no effort needed from you, other than lab prep! All my resources are informed by my more than two decades experience teaching IB DP Bio, so you can be sure you are getting quality resources with everything you need included. IBDP Biology Skills Covered: Practical 1: Use of a light microscope to investigate the structure of cells and tissues, with drawing of cells; Calculation of the magnification of drawings and the actual size of structures and ultrastructures shown in drawings or micrographs.
