The resources include knowledge organisers, cue cards, revision quizzes, mind maps, worksheets, cut and stick, group work activities, co-operative learning activities, quizzes, differentiated worksheets, interactive PowerPoints etc. These resources can be used to accompany a lesson on the topic or as part of a revision lesson. Due to the large quantity of files they have been attached as a Zip file.

A complete set of 9 lesson resources on the A-Level Chemistry topic of Born Haber cycles. In our college, this content is taught over three double lessons. Includes resources on sketching the cycle, (including interactive animations), how to perform the calculations using data from the cycles, definitions of lattice energy, enthalpy of formation, enthalpy of atomisation and electron affinity. Also includes the teaching of charge density (ionic radii & charge), how we use the value of lattice energies to determine complete ionic character/degree of covalent bonding and polarisation. Accompanying the Power Points, are worksheets (with answers included) and homeworks.

An A-Level Chemistry differentiated revision resource on calculating the ideal gas equation pV = nRT. Contains 8 different sections of questions, section 1 starts with the basics, practicing conversions of pressure, volume and temperature into the correct units, the last few sections contain exam style questions. Takes about an hour to complete. The resource is editable with an answer sheet included. Suitable for A-Level Chemistry across all syllabuses.

A resource applicable for the current AQA A-Level Chemistry specification on TOF Mass spec calculations. The questions test students on how to calculate velocity, distance of flight tube, time taken and atomic mass. Answers are included to every question including a hand-written extended answer sheet showing each step of the calculations to assist students who get stuck. The resource usually takes about 60 – 90 mins for students to complete depending on their ability.

A GCSE Chemistry knowledge organiser on topic 2 structure and bonding suitable for the new 2018 GCSE AQA syllabus. Contains information on the structure and bonding of ionic, simple covalent, giant covalent, graphene, fullerenes, metals and alloys. Includes descriptions and diagrams of their structure and explanation of how their strucutre links to their physical properties (melting & boiling points, conductivity etc.

A knowledge organiser on the A-level chemistry practical “preparation of aspirin" from 2-hydroxybenzoic acid and ethanoic anhydride using a phosphoric acid catalyst. The knowledge organiser includes the method and apparatus diagrams and goes into more depth about filtration under reduced pressure, recrystallisation and reflux. I use it in my lessons to go through the procedure in greater depth and then students refer to this when practising questions.

A worksheet on the GCSE Chemistry topic of electrolysis. Contains questions on the apparatus used, oxidation & reduction, ionic equations, electrolysis of lead bromide, aluminium oxide and aqueous solutions. Answers are included.

An A-level chemistry resource on drawing of Born Haber cycles. Each slide is animated showing step by step how to draw Born-Haber cycles for NaCl, LiF, MgCl2, Na2O, CaO and AlCl3.

This is a differentiated A-level chemistry revision resource covering the different types of Ecell questions. There are 8 sections, each one increasing in difficulty. The resource is editable and the markscheme is provided. Could be used in a revision lesson at the end of the topic. There is also useful tips on how to calculate Ecell and writing of cell diagrams. There is one of every type of Ecell question that students could be tested on in an exam. Takes about 2 hours to complete. I also have several other resources like this one in my shop on moles, pV=nRT, redox titrations, entropy, Equilibrium Kc & Kp, pH calculations and also buffer calculations. Each one covers all the different types of calculations they need to revise for the exams.

A lesson on Grignard reactions consisting of a PowerPoint and a worksheet. Suitable for all A-level exam boards. covers the 3 steps in the Grignard reaction and includes information on how to get the reaction started, solvent, conditions and relevant equations. The editable worksheet comes with answers.

An A-Level Chemistry resource on titration calculations suitable for all specifications. The worksheet is differentiated with each section increasing in difficulty. Students complete titration calculations on determining volume, concentration, Mr of a compound, percentage purity, formula of a compound (working out the value of n in Na2CO3.nH20) etc. The resource contains one of every type of titration question they need to answer in an exam. Answers are included. There are 6 different sections and the worksheet takes a standard double lesson for students to complete.

Some A-Level Chemistry resources on the thermodynamics topic of Gibbs free energy. The first resource contains 6 sections of calculations with each section increasing in difficulty. This resource is differentiated and takes about an hour to complete. Is excellent revision on Gibbs free energy calculations and nicely prepares students for the exam with relevant exam standard calculations including a graph. Answers are included. Also included are Entropy worksheets (with answers) on calculating Gibbs and how it is related to the equilibrium constant.

A revision resource with questions on calculating entropy of the system, surroundings, total entropy and entropy of solution for dissolving ionic salts. Answers are included within the editable worksheet which allows students to mark their work and monitor their progress. The questions get more difficult as each section progresses.

An A-Level Chemistry resource on proton (1H) NMR (nuclear magnetic resonance). I use it as a group work activity, students are given the cards and have to solve the spectra using the data table given. Answers are included on a Power Point enabling feedback to the the class.

An Alevel Chemistry resource on calculating very low concentrations of solutions. The worksheet includes questions (and also worked examples which help the students complete the worksheet). Questions on calculating concentration in ppm (parts per million), mass of ions, avagodro’s constant, number of ions etc.) Answers are included.
