The GCSE PAG Tracker helps teachers to with the apparatus track learners’ opportunities and techniques, and to ensure that the practical activities chosen fully cover the requirements. The first set of OCR PAG activities are now available on the qualification pages under the Practical Activities section (; ). These activities are: PAG 1.2 Reactivity of metals PAG 2.2 Microscale electrolysis of copper(II) chloride PAG 3.2 Chromatography of leaf chloroplasts PAG 4.1 Extraction of limonene PAG 5.2 The march of the precipitANTs PAG 6.2 The vinegar dilemma PAG 7.1 Prussian blue investigation PAG 8.2 The disappearing cross Note this set of PAG activities does not fully cover all of the required apparatus and techniques. For full coverage, the following practicals are additionally suggested. Practical activity sheets covering these activities are currently in production, and will be available soon. Alternatively, the weblinks below are to suitable Royal Society of Chemistry activities or CLEAPSS activities. A rate of reaction experiment involving gas collection and heating reagents with a water bath e.g. the effect of temperature on the rate of reaction between hydrochloric acid and – magnesium - Synthesis of salt with purification by crystallisation e.g. synthesis of copper sulfate – – Investigating enthalpy changes e.g. mixing pairs of chemicals and measuring the – temperature change - Flame test on metal salts – Titration of a strong acid and alkali - Suggested activities for each Practical Activity group and each type of activity: PAG Traditional/bench Microscale Kitchen-chemistry
