A series of three lessons prepared for the AQA GCSE C3.2 unit of work about hard and soft water, the process of water softening and the purification of water. Includes PowerPoints, lesson plans, practicals, activities, worksheets, exam questions and videos to accompany the topic.

These sheets ask questions which when answered summarise the whole of the iGCSE Chemistry course, with one sheet per topic. They can be used one at a time, at the end of a topic, or at the end of the year as a revision resource Obviously they don´t go into as much detail as past paper questions but they do provide a basic summary of questions that students must know the answers to in each topic The answers to this exercise are now also available in my shop

This booklet and accompanying PowerPoints covers the Moles topic for iGCSE Chemistry. It would also be useful for other courses, as it covers all of the topics in the list below. The booklet is designed to be interactive and to be filled in by the students, accompanied by the PowerPoints. It includes spaces for worked calculations, exercises, past paper questions (taken from the Cambridge iGCSE papers) and two practicals. The answers to the exercises are also provided for the workbook and are shown on the PowerPoints. What exactly is a mole? How can we convert between masses and moles? How do we deal with diatomic molecules? Converting between mass and moles in compounds Calculating the % by mass of an element in a compound Balancing Equations Reacting Masses Limiting Reagents Percentage Yield Practical - How much copper sulphate can we get from malachite? Percentage Purity Empirical Formula Moles in Gases Moles in Solutions Titrations Practical – What is the concentration of sodium hydroxide? I also have another scheme of work where this booklet has been altered slightly for the Co-ordinated Science Chemistry moles unit.
