Explore our collection of curriculum-linked science practical guides for GCSE and A Level Biology, Chemistry and Physics. Each guide supports teachers, technicians and students with clear methods, apparatus lists, safety guidance, scientific explanations, results analysis and practical teaching resources.
Investigate how pH, temperature and substrate concentration affect catalase activity, with clear guidance on measuring and analysing reaction rates.
View Enzymes Practical →Investigate photosynthetic activity using isolated chloroplasts and DCPIP, comparing relative reaction rates at different light levels.
View Photosynthesis Practical →Use volumetric analysis to determine an unknown concentration, including standard solutions, burette technique, concordant titres and calculations.
View Acid–Base Titrations Practical →Construct metal–metal ion half-cells, measure cell potentials and explore how electrode combinations and experimental conditions affect voltage.
View Electrochemical Cells Practical →Investigate initial rates using an iodine clock reaction, calculate relative rate and analyse how changing concentration affects reaction speed.
View Rates of Reaction Practical →Separate and identify mixture components using thin-layer chromatography, calculate Rf values and assess the purity of samples.
View TLC Practical →Produce standing waves on a stretched string, identify nodes and antinodes, measure harmonics and determine wave speed.
View Standing Waves Practical →Investigate force and extension for a spring, determine the spring constant and distinguish proportional, elastic and non-linear behaviour.
View Hooke’s Law Practical →Investigate osmosis in potato cylinders across a range of sucrose concentrations and estimate the isotonic concentration from percentage mass change.
View Osmosis Practical →Compare the effectiveness of antimicrobial treatments using zones of inhibition while reinforcing aseptic technique, controls and safe incubation.
View Antibiotics Practical →Compare metal reactivity using metal-salt solutions, identify displacement reactions and use observations to construct a reactivity series.
View Displacement Reactions Practical →Carry out flame tests safely and use characteristic flame colours to identify selected metal ions while controlling contamination.
View Flame Tests Practical →Prepare hydrated copper(II) sulfate crystals from an insoluble base using heating, filtration, evaporation and crystallisation.
View Making Salts Practical →Measure trolley acceleration on a ramp using light gates and a data logger, then examine how force or mass affects motion.
View Acceleration Practical →Determine the density of regular and irregular solids using mass, dimensions and water displacement, with calculations and uncertainty considered.
View Density Practical →Map magnetic fields around bar magnets using plotting compasses and iron filings, including interactions between like and unlike poles.
View Magnetism Practical →We are continuing to expand this collection with practical experiments covering more GCSE and A Level Biology, Chemistry and Physics topics. Each guide is designed to support safe preparation, effective teaching, accurate practical work and confident analysis of results. Please contact us if you would like us to produce a particular practical guide or if you have any feedback on our existing guides, we'd love to hear from you.
