Versions for colour and black and white printing and a detailed mark scheme. October 2024 update: added more space for writing answers.

Worksheet on two pages covering plant disease for the AQA 9-1 biology GCSE specification. Topics include tobacco mosaic virus, Agrobacterium tumefaciens and rose black spot, as well as one calculation practice. Level is fairly basic, without many complicated questions. Versions of the worksheet are included for colour and black and white printing. Pictures, diagrams and mark scheme are included.

Helping students understand chemistry, I’ve realised you have to hold a lot of things in your head to even know what a chemistry textbook is talking about. A lot of students find they just can’t hold together all the things they have to know at once. Back in 2015, I realised what students can benefit from is a concentrated set of notes, like a dictionary or a glossary but in full sentences, that fits as much of chemistry as you can on a single page that you can keep referring back to to decode what’s going on. My students liked it, and I’ve worked to create definitions that are concise and clear to fit as much as possible on one page. It’s helpful for giving students just starting the course to have to refer to every now and then, and for students who need remedial help because the concepts are slipping out of reach. The notes include quick basic definitions of: structure of an atom how to read the periodic table ionic, covalent and metallic bonding properties of ionic chemicals oxidation and reduction properties of ionic chemicals acids, bases and alkalis the idea that in neutralisation the salt name depends on the acid

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)

Two-page link-up-the-boxes worksheet and two-page written worksheet recapping definitions of community, habitat, ecosystem and biotic/abiotic factors, along with case study questions. For the AQA 9-1 biology GCSEs: based on collating past paper questions I’ve found the definitions of the terms are important for students to know, but suitable for other courses. The link-up-the-boxes worksheet is deliberately written to be very easy for students with low knowledge and confidence. The written worksheet covers biotic factors, quadrats, transects and competition, along with a calculation question and practice identifying types of habitat. Versions for colour and black and white printing and a mark scheme are included. Could also be suitable as a quick recap exercise for A-level students.

Revision notes for A-level chemistry on cracking for the AQA A-level specification in comparison table format, and the same table but empty for students to fill in themselves. An example cracking equation is given for students to fill in and suggest names for the products and there is an emphasis on practicing the unit conversions and working out the formulas and names of products. Update for 2023: expanded resource based on student feedback, with a link to a video demonstration and bullet-point list of products.

Notes on one page covering all the tests for cations for Edexcel GCSE chemistry, including the precipitation equations, and links to videos of them being done. I’ve also included model equations, both complete and ionic, for the precipitation reactions, with examples for a +2 and +3 ion, and the equation for the ammonium ion test. Versions included both in colour and in black and white for photocopying. Update: a missing 2 in a formula has been added. My apologies for the mistake.

Notes on the tests for anions for AQA GCSE chemistry courses on a single page. A lot of work went to squeezing everything in! 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. There’s versions of the resource for colour and black and white printing. This set of notes was particular written targeting the AQA GCSE chemistry course, but it’s suitable for most GCSE courses as well as recap for students coming in to A-level.

Revision notes of the negative ions for Edexcel GCSE chemistry on one page, including both complete and ionic equations for the reactions. Versions both in colour and for black and white printing. 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.

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.

A famous painting proves a jumping-off point for examining ecology and national heritage in this worksheet for students applying to study biology, environmental sciences and geography at university. There’s two formats: a worksheet for students to take home, but also if you want to replicate the format of a university interview with an interviewer posing questions, a sheet containing the painting to show the student as stimulus material and a set of questions and answers for the interviewer, with some possible extra hints if the student’s struggling. There’s questions about experiment design and statistical test to choose too. On a difficulty scale, I’d put this as about a three out of five: it’s an interesting case study with a nice, evocative stimulus material to get students thinking, but doesn’t really go beyond the A-level courses.

Worksheet and worked examples with two intuitive stories of how people could need to use a reciprocal to find a whole quantity when they only know a fraction of it. Could be suitable for KS2, KS3 or advanced KS1 students. There’s versions in poster form, a problem sheet and (probably most useful for students) a version with notes and worksheet merged onto one page. (The answers are 30 minutes and 12 minutes.) To make it approachable for students in a range of countries I have versions where the money is UK pounds, the Euro or dollars-with appropriate Emoji images! Comment if you’d like a version in a different currency, I’ll add it.

Some of the hardest questions for many GCSE chemistry students are the written questions, explaining things like why the rate of reaction increases when you increase the temperature, and how the position of equilibrium shifts. So I’ve written a one-page set of notes that covers all these questions, fitting them onto a single page. These notes cover: how temperature and concentration affect rate of reaction melting point of ionic, molecular and giant covalent chemicals equilibrium position conductivity It makes chemistry so much easier for students having everything on a single page. Particularly intended for GCSE chemistry but I think it’s also pretty helpful for A-level students just starting the course who need to recap what they did last year, many will have forgotten these topics. Purchase includes a “general” set of notes not written for any particular exam board, and specific versions for students taking Edexcel iGCSE and the AQA 9-1 GCSEs. Changelog: a missing ‘no’ has been added in conduction. My apologies for the glitch.

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.

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.
