Core practicals Study guides, Revision notes & Summaries

This document is a detailed and extensive guide for all of the 12 required practicals for AQA A level and AS Level chemistry. Revising the core practicals for exams can be difficult, so I prepared a resource which not only contains the method for each practical but also highlights where specific equipment/techniques/chemicals are being used and explains WHY it is being used (learning these will make core practical-related questions significantly easier). Key observations have additionally been h...

A complete summary of core practicals 1-18 from the Edexcel SNAB A Level Biology course. Includes mark scheme specifics and key details for each procedure. Includes the following practicals: Effect of caffeine on HR in Daphnia, Vitamin C content of food and drink, Membrane permeability (beetroot), Enzyme and substrate concentrations, Observing stages of mitosis, Identifying structures in a stem, Plant mineral deficiencies, Tensile strength of plant fibres, Antimicrobial properties of pl...
