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.

These sheets ask questions which when answered summarise all of the Chemistry topics covered on the iGCSE Coordinated 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

This lesson was planned as a stand alone investigation lesson for KS3, designed to allow students to work on their practical skills. When observed it got an ´Outstanding´ (for what it is worth), and I have attached the lesson plan. It involves a ´poisoning´ scenario where students are asked to identify an unknown powder used to poison someone. Students are asked to choose the equipment that they will use, test some named powders and use this to identify the unknown powder. They are then asked to write a letter to a detective (using a level ladder as a guide) explaining how they identified a poison. They should then peer assess against the level ladder.

These PowerPoints were planned as part of the IB scheme of work on Structure and Bonding and cover the necessary content for both the Standard and Higher Level topics. They would also be suitable for other post-16 courses. Included are fully completed PowerPoints, student versions of the PowerPoints with sections to complete independently and some exam style questions. Topics included are: Ionic Bonding What is ionic bonding? Common positive and negative ions Working out the formula of ionic compounds Giant ionic lattices Properties of ionic substances Covalent Bonding What is covalent bonding? How to draw Lewis structures How to tell if a substance will be ionic or covalent The Octet rule and how it can be broken Coordinate bonds and compounds which contain them Resonance structures VSEPR theory Shapes of molecules with up to 6 bonding pairs Shapes of molecules with up to 6 bonding and lone pairs Giant covalent bonding - diamond, graphite and silica Intermolecular Bonding - London forces - Permanent dipole-permanent dipole forces - Permanent dipole-induced dipole forces - Hydrogen bonding - Solubility and intermolecular forces Metallic Bonding How do we describe a metallic structure? How to predict which metal will have the high melting point Properties of metals Properties of alloys Advanced covalent bonding, electron domains and molecular geometries Assigning formal charge Exceptions to the octet rule Formation of sigma and pi bonds The composition of single, double and triple bonds Resonance hybrids and delocalisation The structure of benzene - Kekule and delocalised Absorption of UV light in the atmosphere Catalysis of ozone depletion by CFCs and NOx gases Hybridisation sp3, sp2, sp hybridisation: how it happens, resulting shapes and how to identify molecules with each type of hybridisation.

This 86 slide PowerPoint was planned as part of the IB scheme of work on Periodicity, and covers the necessary content for Standard Level topics. It would also be suitable for other post-16 courses. Included are the fully completed PowerPoint, a student version of the PowerPoint with sections to complete independently and some exam style questions. Topics included are: - The development of the Periodic Table - The structure and arrangement of the Periodic Table - How metallic/non-metallic properties change as you go left to right across the periodic table - How atomic radius of elements changes across periods and down groups, and why this occurs - How ionic radius of ions changes across periods and down groups, and why this occurs - How first ionisation energies of elements changes across periods and down groups, and why this occurs - How electron affinity of elements changes across periods and down groups, and why this occurs - How electronegativity of elements changes across periods and down groups, and why this occurs - Properties and reactions of the Group I metals - Properties and reactions of the Group XVII non-metals - The acid-base character and reactions of the period 2 and 3 oxides

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 2 week KS3 scheme of work was designed to take 4x100 minute lessons. The aim of the project is to guide students to research, test, ´market´ and evaluate their own handwarmer. The lessons are broken down as follows: Lesson 1 - Research and Planning Lesson 2 - Testing hand-warmer options Lesson 3 - Product Design Lesson 4 - Pitching the design to peers and evaluation Originally designed to link Science with Business and Enterprise, it could also be used to encourage the use of transferable skills in science, and would make an independent and interactive ´end of year´ activity.
