Flow diagram showing the menstrual cycle on one page. Suitable for AQA 9-1 GCSE, Edexcel 9-1 GCSE, Edexcel iGCSE and Cambridge iGCSE exam boards, among others. Clean modern design, easy to follow. Explains roles of follicle stimulating hormone, luteinising hormone, oestrogen and progesterone, the pituitary gland, ovaries and corpus luteum. I have a separate version for OCR Gateway GCSE science-that course has slightly different content.

One-page reference giving a case study of how to answer questions on experiment design. Suitable for GCSE and A-level students. The case study is testing catalase-catalysed decomposition of hydrogen peroxide at different temperatures. This set of notes is oriented towards exam technique and how to answer multi-mark questions on this kind of topic: the need to define and set up an independent variable, to measure a dependent variable, define some control variables, and maybe plot the data and mention some safety precautions. I specifically mention that you don’t need to give too many control variables-students often think they can get more marks listing dozens.

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.

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-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.

Graphic poster listing all the products of combustion and harms they cause. Suitable for all GCSE and A-level courses. Colour and black and white versions included.

One-page set of notes on differential ultracentrifugation to extract organelles, covering homogenization, the ice-cold, buffered, isotonic solution, extracting different organelles and links to recommended videos. This set of notes is particularly targeted towards revising the practical come exam time-it doesn’t go into a detailed practical methodology for fractionation but gives exam-oriented explanation of how a centrifuge works, what a cold, buffered, isotonic solution is and why it’s needed. These notes should be suitable for all major A-level courses, but they’re particularly designed to help AQA students taking into account points on the mark schemes for the 74011 specimen paper Q1, 74023 2018 Q5 and 74011 2018 Q7, which would be great for practice alongside these notes.

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.

Poster showing all the most common ions students need to know about and their charges, and a reminder that negative ions have gained electrons and positive ions have lost them. Clean modern design, great for GCSE and A-level students for all courses. Most courses don’t have phosphate on the list of ions to know, so I’ve left it off the main list. But in case your course does need it, I’ve added a second version of the sheet with the phosphate ion added. If you like this resource, you might want my exercises working out formulas of ionic chemicals. Update, April 2024: added zinc and some hints about iron(II) vs. iron(III)

Worksheet as a reminder of how the ideal gas law works, showing all the unit conversions and with a model calculation. Also includes a diagram of why a cubic metre = 1 million cubic centimetres, something students often have trouble with. Suitable for all A-level chemistry and 16+ exam boards e.g. AQA, Edexcel, OCR, Cambridge. The assumptions the ideal gas law makes are also explained.

Poster naming some of the most common inorganic reactions at GCSE and A-level chemistry: metals reacting with water and acid, metal hydroxides, oxides, carbonates and ammonia reacting with acids. Clean, modern design highlighting similarities between the reactions e.g. water formed. There’s versions both in colour and in black and white. The formulas of the negative ions are given for nitrate, chloride and sulfate ions. Suitable for all major GCSE exam boards (e.g. Edexcel, AQA, Cambridge), and I find it really helpful to help A-level students recap what they learned at GCSE and forgot over the summer!

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.

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.

One-page reference of the most common oxidation numbers for A-level with clear layout. Lists the elements which have particularly unpredictable oxidation numbers and gives case studies of them. Also lists the most common oxidation numbers of transition metals, with half-equations for the reduction of manganate(VII) and dichromate(VI) ions. Versions in colour and in black and white for photocopying. Specification references include OCR A 2.1.5 and AQA 3.1.7.

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.

A-level osmosis required practical notes, targeting courses including AQA 3.2.3 and required practicals 3 and 4 and OCR A 2.1.5. The notes include diagrams on how to plot a graph of the data and some exam technique practice on how to answer questions on getting valid data, and links to good videos. The notes are bullet point style and easy to read. This set of notes is particularly targeted towards revising the practical come exam time and doesn’t include a detailed practical methodology. NOTE: my apologies, the original uploaded version had some words missing explaining the effect of evaporation on water potential, this has now been corrected.

Diagram of Born-Haber hydration, solution and lattice enthalpy laid out at a large size with a lot of space for notes and comments. Two versions, one for AQA which uses the term lattice dissociation enthalpy, the other for OCR and Edexcel which just call it the reverse of the lattice enthalpy. Specification targets include: AQA 3.1.8.1, OCR A 5.2.1, Edexcel 13.1 Changelog, September 2023: more detail on the calculations.
