Revision notes on the Arrhenius equation for the OCR A A-level chemistry specification on two pages. A lot of students by the second year of A-level have forgotten how to do things like find the equation and intercept of a straight line graph, so this set of notes has a lot of recap. There’s also a lot of detailed breakdown of the log equation and how it’s a straight line graph. I explain what ln(A) is and how to calculate it. Includes a lot of model calculations, recap of straight line graphs and explanation of the confusing units of the H432/01 2018 paper’s graph. Update, 13/05/24: a missing 0 in the explanation of the 2018 paper’s units has been corrected, my apologies for the glitch.

Notes on one page covering all the tests for cations for Edexcel iGCSE 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. Versions included both in colour and in black and white for photocopying.

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.

Gases covered are tests for hydrogen, oxygen, chlorine, ammonia, sulfur dioxide and carbon dioxide. The reaction of ammonia with hydrogen chloride is also covered.

Worksheet covering the equations and rules for solution electrolysis for AQA 9-1 GCSE higher chemistry on two pages. Covers electrolysis of sodium chloride solution (brine/saltwater), copper sulfate solution with inert graphite electrodes, and electrolysis of pure water. Diagrams, a mark scheme and links to recommended videos from Fuse School and ChemJungle are included. Versions in colour and converted to black and white.

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.

Notes on the tests for anions for OCR Gateway GCSE chemistry on a single page. 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. A lot of work went to squeezing everything in clearly! There’s versions of the resource for colour and black and white printing.

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 on one page each covering all the tests for anions and cations for AQA GCSE chemistry, including the precipitation equations. Versions both in colour and in black and white for photocopying.

Notes on the tests for gases and for water for AQA 9-1 chemistry GCSE, with notes on one page and a table on a separate sheet. 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.

When doing tuition using an online platform like Zoom or Skype, you often need to put formulas into the chat box or onto an online whiteboard that wasn’t designed for scientific use and doesn’t support constructing superscript and subscript characters. Also, you may need to write out formulas very quickly if your student asks something unexpected. So this is a list of a huge number of formulas for the major GCSE and iGCSE chemistry courses using the Unicode superscript and subscript characters, indexed and ready to go for tuition. (For other countries, it should be suitable for tuition of students up to around age 16.) Covering thirteen pages, sections include: common ions organic chemistry: combustion, alkene hydration, alcohol oxidation acid-base: acids with metals, carbonates, oxides, hydroxides, ammonia reactions common reversible reactions: Haber process, syngas, the Contact process inorganic reactions: thermal decomposition of calcium carbonate, electrolysis (water, sodium chloride, copper sulfate with graphite or copper electrodes), displacement, thermite, metals reacting with oxygen and water, halogen displacement, both with overall and ionic and half-equations) the chemical tests: precipitation, hydroxide tests the chemical reactions of biology: respiration and photosynthesis core maths equations that might be needed in science, such as area of a circle, volume of a sphere, volume of a cylinder etc. some prebuilt unit conversions Versions of important equations are included in multiple forms, such as with or without state symbols, so you can select one that matches the level you’re working at with the student and keep the lesson flowing. I’ve used these formulas for a huge number of paid tuition jobs, and couldn’t do anything without them-they’ve really helped me make things clear to students, keep lessons moving and give a professional impression. Many students have asked me how I make equations appear looking good in the chat of a call, or even asked me for this document to use themselves! The document is an editable rtf and docx file with the equations and all the superscripts and subscripts and some common symbols at the start. You can build your own equations if you need them or edit or reorganise the document to suit your way of working.

Lesson plan on ionic bonding, featuring a lesson plan presentation, one-page notes for students to take home and a question sheet for students to do. Covers ionic bonding, state at room temperature, common properties, conductivity of electricity, strength and dot and cross diagrams for forming ions.There’s diagrams, pictures and links to two recommended YouTube videos. The question sheet is intended to be a graduated scheme of work with first fill-in-the-blank and then written questions. Written for AQA 9-1 GCSE chemistry and also for Edexcel GCSE and iGCSE chemistry, but suitable for all the major exam boards. It’s also good for introduction to A-level as a recap.

Combined lesson plan for Edexcel iGCSE chemistry: 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. Also suitable as a recap for A-level students. 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 and types of steel. 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 videos for revision. Besides covering metallic bonding and content like specific types of steel, the presentation introduces themes for future lessons, like that metal recycling saves energy and rust prevention.

Revision notes of the negative ions for Edexcel iGCSE 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.

Two page set of notes in table format on intermolecular forces, listing the forces, where they come from and how strong they are: London 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 London 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 London forces/van der Waals forces/instantaneous-induced dipole forces, so if you teach multiple courses you’re always covered: OCR, Edexcel, AQA, Cambridge. I sell multiple SKUs of this set of three notes to advertise at teachers searching for different courses, but they contain the same content: all three files in the same pack.
