Notes on one page covering all the tests for cations for OCR Gateway GCSE chemistry, including the precipitation equations. I’ve also included model equations, both complete and ionic, for the precipitation reactions, with examples for a +2 and +3 ion. Versions included both in colour and in black and white for photocopying.

Flow diagram showing the menstrual cycle on one page, suitable for OCR Gateway GCSE biology. Clean modern design, easy to follow. Explains roles of follicle stimulating hormone, luteinising hormone, oestrogen and progesterone, the pituitary gland and ovaries, as well as the hormonal contraception methods. Two versions are included. One includes details of contraception methods, one doesn’t to give you a version with less text. This version of these notes is designed for OCR Gateway GCSE biology. I have an alternative version of this diagram for the AQA and Edexcel courses (amongst others) which contains some extra content, including more details about progesterone.

Notes and worksheet on series and parallel circuits covering voltage, current and resistance for the Edexcel 9-1 GCSE. There’s a version filled in for revision and a blank worksheet for students to fill in themselves. The notes aim to put all on one page all the rules of potential difference, current and resistance for series and parallel circuits, something students have a lot of trouble managing. In particular, it shows the way that the rules of series and parallel circuits for current and PD are opposite to one another, something also stressed in a “how do I remember all this?” guide at the bottom. A power triangle for Ohm’s law is also included to help students know what calculation to do. These notes should be suitable also for teaching OCR Gateway GCSE physics. Please note that this set of notes isn’t needed for Edexcel international GCSE which doesn’t go as far into the topic.

I’ve found respiration is one of the most important things for students to get right studying biology. The equations are so important, but many GCSE and even some weaker A-level biology students can’t instantly give them. I explain to students that they’re an instant grade boost. Here’s a worksheet and set of notes on one page on the most common respiration questions. There’s the word equations, a guide through the standard question about how your heart and breathing rate change with exercise, and there’s links to some recommended videos. Versions included for colour and black and white printing. Full mark scheme included with the worksheet. Remembering the equations for respiration is one of the last things I always go over with students just before their exams, because it’s such a morale booster to instantly get full marks on one of these questions. I will never forget what one student told me in 2021: “It came up! Exactly what you said, it came up!” Although this worksheet and set of notes works for students taking any exam board and A-level students who need a recap, it was particularly written with an eye to AQA 9-1 GCSE mark schemes. Questions consulted included: 8461/1H 2021, question 7 8461/1F 2020, question 4 8461/2F 2018, questions 7 and 11 BL2HP 2017, question 5 I’ve got a separate set of notes for Edexcel iGCSE which uses the term “lactate” instead of lactic 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)

Poster showing how you divide by a fraction. There’s two case studies, one simple, dividing a fraction by another fraction, and another more complicated, starting from a whole number. Suitable to be printed large on a classroom wall or at small size for students to stick into their exercise book or folder. Suitable for students around KS2 to KS3 and weaker GCSE students. As an advanced point for students doing well, it introduces the idea of reciprocals.

Explanation of what “per” means: that it means you need to divide. Two stories are given as examples. Suitable for primary school maths and science. Because people have a lot of trouble learning this, this could be useful across a lot of ages, KS1, KS2, KS3 or weaker GCSE students who need a bit of help.

One-page set of notes on confocal microscopy targeting A-level biology (especially OCR A) with some selected images and a link to a recommended video. Although suitable for other courses, these notes were specifically targeted at OCR A-level biology A. The focus is on the images produced by confocal microscopy rather than on the details of how the mirror system works. Questions studied writing this pack (and recommended for exam technique) included: AS-level unit 2, question 1 from 2017 AS-level unit 2 specimen, question 6 (MCQ) A-level 2020 paper 1, question 2 (MCQ)

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.

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

Combined lesson plan: a presentation on metallic bonding, simple fill-in-the-blank questions questions and a harder sheet of written questions linked to the presentation, and a take-home set of notes on one page. Covers metallic bonding, conduction of electricity and heat, the fact that metals are malleable/ductile and alloys. Starts with a mixer exercise covering uses of metals and also includes some properties and uses of the most common metals. Need to use this lesson plan in a hurry and want to deliver a polished lesson? I’ve got you covered: each slide ends with a full stop marking that it’s the last point on the slide so you know when the slide’s going to change. Also, each exam question slide has a spare line before the answer is revealed so you don’t accidentally show the answer too early. Included is a fairly easy fill-in-the-blanks worksheet and an exam-style written questions worksheet matching questions on the presentation, and the mark schemes for both. Both worksheets have pictures and diagrams to stimulate students. The notes have diagrams and also links to two recommended YouTube videos for revision. The pack is suitable for all specifications for GCSE and is useful for recap for students coming into A-level. It’s particularly been written for the AQA trilogy and synergy chemistry GCSEs and hits specific phrasing from their mark schemes. Doing Edexcel iGCSE? I now have a specific version for that course covering things like the types of steel. Besides covering metallic bonding, the presentation introduces themes for future lessons, like that metal recycling saves energy and rust prevention.

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.

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.

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.

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.
