Notes on one page each covering all the tests for anions and cations for Edexcel GCSE chemistry, including the precipitation equations. Versions both in colour and in black and white for photocopying. With the positive ion tests, I’ve included model equations, both complete and ionic, for the precipitation reactions, with examples for a +2 and +3 ion. With the negative ion tests, there’s both a full and ionic equation for carbonate, sulfate and halide ion reactions to give students good models. To show the differences in formulas between compounds of metals that form +2 and +1 ions, there’s equations for both sodium and calcium carbonate too, and details of what happens if you use different acids.

Notes on gas chromatography for the OCR A-level chemistry A specification on a single page. It particularly emphasises knowing how separation is achieved, a common topic for tough questions where getting the phrasing right is absolutely essential. There’s pictures and diagrams, explanation of a calibration curve and links to three top recommended videos. Questions looked at to prepare these notes (and recommended for revision) included: October 2020 paper 1, question 13 (MCQ) June 2015 paper 4, question 1 June 2012 paper 4, question 5 June 2018 unit 2, question 21 c i)

This two-page resource lists pathogens, transmission routes, disease effects, treatment methods and other facts for the human diseases on the Cambridge International A-level biology course. The large number of disease case studies on the course is something students need a lot of help with. A blank worksheet version is also included for students to fill in themselves. To help students build up a common sense knowledge of the kind of issues surrounding these diseases that could be important in future and likely topics of exam questions, there’s a section on “other things to know” explaining issues like malaria potentially being spread by global warming. That should make this set of notes particularly useful for students aiming high and looking to study medicine, nursing and biosciences degrees in future or getting ready for interviews. Although flu is not one of the “official” case studies on the course, because it’s covered in the vaccination topic notes on it are also included. I’ve had positive feedback from students who found it interesting and felt that it gave them a sense of issues in modern medicine-one student studying history A-level said it really helped put studying AIDS in history in context.

Two-page revision checklist of all the transition metal colours on the OCR A A-level chemistry specification. Also includes list of notable catalysts, half-equations with dichromate(VI) and manganate(VII) ions, lists of the types of stereoisomerism, and links to videos of most of the reactions. There’s versions both in colour and black and white. These notes are inspired by vocab lists you use when you learn a foreign language-you cover the answers and read through. Getting the points to learn into an order you repeat over and over is really helpful for learning everything. Changelog, 12/3/23: a broken link has been fixed.

One of the hardest questions the examiners can ask at A-level is how to predict the second and third ionisation energy. It’s not clearly labelled in the textbooks how to do this. So here’s a three-page set of notes on how to do this, working through some exam-style questions. Specification references include: OCR A 3.1.1, AQA 3.1.1.3

One-page poster and revision notes showing how to work out the formula of ionic chemicals. Includes a list of common ions, and the three scenarios: swap and drop, the ions have the same charge, and there’s more than one of an ion made of more than one atom so you need brackets. Versions both in colour and carefully converted into black and white. Then there’s also a question sheet working out the formulas of 21 chemicals, and the answers on a separate sheet. Suitable for both GCSE and A-level students-I find it really helpful as a recap for A-level students to recap the topic, since they’ve often forgotten it from GCSE. September 2023 update: based on feedback from students, I’ve explained more about what iron(II) and iron(III) are, and turned the part about when you use brackets into a checklist of questions to ask. I’ve also created an additional version of the questions split into two sets so one can be homework. The questions in the homework set 2 are similar at each level but the hardest questions are in set 1.

Two page set of notes in table format on intermolecular forces, listing the forces, where they come from and how strong they are: instantaneous dipole-induced dipole forces, permanent dipole-dipole, hydrogen bonds. Also includes notes on which type of chemical has what forces. Page 2 explains how aldehydes and ketones and esters are hydrogen bond acceptors. Following the example of Chemguide, explains permanent dipole-dipole as more adding a bit of strength on top of instantaneous dipole-induced dipole forces forces than making the molecule highly polar and hydrophilic like hydrogen bonding. Bold, eye-catching typography and careful design sets this lesson plan out. Special bonus! This pack contains three sets of notes depending on what your course calls instantaneous-induced dipole forces/van der Waals forces/London forces, so if you teach multiple courses you’re always covered: Cambridge/CIE, OCR, Edexcel, AQA. I sell multiple SKUs of this set of three notes to show up on searches for teachers teaching different courses, but they contain the same content: all three files in the same pack.
