Notes on gas chromatography and GC-MS for the current Edexcel A-level specification. There’s pictures and diagrams, explanation of a calibration curve and links to three top recommended videos in this one-page resource.

Notes and diagrams on epigenetics for the AQA course, starting from some simple analogies to the real world. I also give the core definition AQA have asked for of epigenetics, which isn’t clearly stated in the textbook but came up on a specimen paper. There’s links to tons of YouTube videos explaining how epigenetics works, and a mnemonic for remembering euchromatin and heterochromatin. Length is two very well-filled pages: you could print it double-sided as a resource for students to keep. Could also be useful for students taking OCR as extension material.

This two-page resource lists pathogens, transmission routes, disease effects, treatment methods and other facts for human diseases on the OCR A-level biology A 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, and multi-drug resistant TB. 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. I’ve mentioned recent developments since the specification was published that would be worth knowing for interviews. 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 helped put studying AIDS in history in context.

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.

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.

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.

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.

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.

Notes on the tests for gases and for water for Edexcel 9-1 chemistry GCSE on one page. The notes include an explanation of what the tests tell you about the properties of each chemical and links to recommended videos. Versions both in colour and in black and white for photocopying. Gases covered are tests for hydrogen, oxygen, chlorine, ammonia, and carbon dioxide.

Worksheet covering wave speed, frequency, and wavelength, on two pages, targeted for Edexcel 9-1 iGCSE physics. Intended to provide a graduated scheme of work from definitions to calculations of wavelength, frequency, wave speed, time period, longitudinal and transverse waves and taking in unit conversion and significant figures. There’s diagrams and power triangles for the core equations for the student to practice using and a mark scheme.

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!
