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.

Five page revision notes on Gibbs free energy, for the OCR A specification. Covers the standard trick questions, graphs against temperature, and includes a range of worked examples, diagrams of the graphs, types of reactions where ΔH and ΔS have different signs and unit conversion examples.

One-page resource on electronegativity, covering a bullet point definition of electronegativity, polar bonds, the effect of dipoles cancelling, and which elements are most electronegative. Links to other areas of the course are made by explaining that although electronegativity is what you see in covalent bonded molecules, it correlates with higher first ionisation energy. Suitable for all A-level specifications, but particularly ties into the AQA and OCR content. An extract of a table of electronegativity is included covering all the common non-metals.

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.

Diagrams showing conjugate acid-base pairs with a bold, vibrant, eye-catching design that would look good for revision notes. Suitable for courses such as the Edexcel A-level chemistry specification, section 12.1, AQA, OCR and others. Covers dissociation of strong and weak acids, and a strong acid protonating a weaker acid. Versions of the resource in colour and in black and white for better photocopying are included.

Notes with diagrams and video links on the Rutherford/Geiger/Marsden gold foil experiment. Explains the plum pudding model, why they used alpha particles, what Rutherford expected and finishes with a bullet point list of features of the modern view of the atom. Covering one page, the notes are suitable for GCSE physics and particularly targeted at AQA GCSE physics. It could also be used for OCR Gateway GCSE chemistry and physics and Edexcel 9-1 physics.

This free resource shows how people tend to get their eye diverted by an eye-catching big diagram or graph or picture, and not read the text above it. I regularly show this to my students to help them understand that examiners write exams downwards, and that often the very start of the text before a picture or diagram hides vital information that they can easily skip over. It really helps them visualise what’s going on and the importance of looking everywhere for the information to solve questions. They often burst out laughing when they get the joke. This image was based on a popular meme distributed without copyright statement whose original author I have not been able to trace, so I’m making it available for free. A couple of different versions are included in colour and black and white.

The two main types of Hess cycles shown on a poster: cycles with combustion enthalpy data and formation enthalpy data. There’s versions both in colour and black and white. The diagram focuses on teaching them using a vector method which shows which arrow needs to be reversed. The answers of what to do are on the side of the poster.

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

Colourful revision notes in checklist form of all the bond angles for the AQA course over two pages. It’s very helpful to be able to run quickly down a list of all the bond angles and check you remember them-this is very common in foreign languages where you have to learn lots of vocabulary: you cover the answers and run through them one by one. Lists of both the standard case study chemicals from the textbooks, and also others students may run into e.g. organic chemicals, which the textbook doesn’t link to this topic but exam questions may do. There’s also an explanation of the key points to make in explaining why bond angles exist based on past paper questions. There’s versions both in colour and black and white.

You get a much better response explaining cyclic AMP when you draw it as a hat that makes enzymes happy when they wear it! One-page revision notes on cAMP for the AQA specification, with links to YouTube videos of some of the processes discussed. I am thinking of expanding this into a more full set of notes including details of the adrenaline receptor and with more diagrams-please comment if that’s something you’d want. It’s offered for free in the meantime.

Ready reference notes on the group 7 elements, covering their colour and state as elements, their colours dissolved in water and organic solvents, the precipitation reactions with silver nitrate, and their redox reactions with concentrated sulphuric acid. Both an attractive, colourful version showing all the colours and a version in black and white for photocopying. Suitable especially for the AQA exam board. I’ve also added a version squeezing everything onto a single page. It looks very compact but won’t photocopy well as well as the text gets quite small.

You get a much better response explaining cyclic AMP when you draw it as a hat that makes enzymes happy and working harder when they wear it! One-page revision notes on cAMP for the OCR specification, combining the different places it’s used on the course (adrenaline receptors, ADH in the kidney collecting duct, lac operon of bacteria). Also has links to YouTube videos of some of the processes discussed. I’m thinking of expanding this into a larger resource covering this topic-contact me if that’s something you’d particularly want. It’s offered for free in the meantime.

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.

One-page poster of the transition metal formulas and colours of aqua ions and reactions with hydroxide ions, ammonia, carbonate ions and HCl. Covers Fe2+, Fe3+, Al3+, Cu2+ and Co2+ ions. Versions in full colour and black and white. For AQA A-level chemistry. These notes are inspired by vocab check 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. UPDATE, October 2023: based on feedback from students, more details on the cobalt complexes and the problem of what you are and aren’t asked to know, the half-equation for oxidation by dissolved oxygen in alkaline solution has been added, the equation of ammonia acting as an alkali in water, and an explanation that on non-course materials you may see the hydroxide formulas without showing that they’re hydrated.

Image on how people can stop and slow down climate change using vivid photos from around the world. As four answers, I’ve chosen four things that children can realistically do themselves: avoiding using cars, using energy less like heating and air conditioning, recycling and eating less meat and dairy products. There’s also a version with blank spaces for students to fill in their answers. Useful for geography, chemistry and science, plenary and general citizenship lessons. If your teaching prefers the wording “climate change” rather than “global warming”, I also have a poster saying this, content is otherwise identical.
