Two page set of notes in table format on intermolecular forces, listing the forces, where they come from and how strong they are: van der Waals, 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 van der Waals 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 van der Waals forces/London forces/instantaneous-induced dipole forces, so if you teach multiple courses you’re always covered: AQA, OCR, Edexcel, Cambridge. I sell multiple SKUs of this set of three notes to advertise at teachers teaching different courses, but they contain the same content: all three files in the same pack. 2024 updates: clearer diagrams of the hydrogen bonds and dipole-dipole forces and new explanations based on student feedback.

Worksheet for the Edexcel 9-1 GCSE biology specification on genetic definitions and genetic crosses on two pages. Dominant and recessive, alleles and genes and Punnet squares are all covered. Sensitivity note: the worksheet includes cystic fibrosis as a case study. This pack is almost identical to my AQA pack covering the same content, you could use either if you teach both courses. Specification reference: B3.12, B3.13, B3.14.

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.

One of the hardest questions the examiners can ask at A-level is how to predict the second and third ionisation energy. It’s not clearly labelled in the textbooks how to do this. So here’s a three-page set of notes on how to do this, working through some exam-style questions. Specification references include: OCR A 3.1.1, AQA 3.1.1.3

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.

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!

Two-page worksheet on plant hormones for the Edexcel 9-1 biology GCSE. Covers phototropism, geotropism, gibberellins and their industrial uses, ethene and an experiment design questions. Versions in colour and for black and white printing. There’s an in-depth mark scheme. Doing AQA GCSE? I have a separate version. Doing Edexcel iGCSE? This pack isn’t needed, the course doesn’t go into so much detail.

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.

Notes on the tests for gases and for water for Edexcel 9-1 chemistry iGCSE 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.

Notes on the tests for gases and for water for Cambridge chemistry iGCSE 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, sulfur dioxide and carbon dioxide. The reaction of ammonia with hydrogen chloride is also covered.

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.

Two-page worksheet for students to fill in covering reflex actions, case studies, synapses and drop tests, targeting the AQA 9-1 biology GCSE but suitable for other courses like Edexcel. An in-depth mark scheme is included. Questions consulted include the 84612H specimen paper and the 2018 paper. Update, December 2023: based on student feedback, added more hints and re-ordered some questions to make the pack flow more naturally.

Fill-in-the-blanks two page worksheet covering blood glucose regulation for AQA GCSE 9-1 biology. Topics covered include the meaning of homeostasis, type I and II diabetes, treatments and effects if not treated. The worksheet is particularly written for supporting one-on-one and small group tuition where the tutor can continuously guide the student, as there’s a lot of answers to fill in to practice spelling and writing key words. A diagram of blood glucose regulation and a full mark scheme is included. Based on personal experience, the worksheet was written with a goal of sensitivity to any students who have diabetes or relatives who do; links to trustworthy medical sources are given for students who want/need more information. The worksheet was written based on checking mark schemes such as the 2019 paper.

Worksheet covering the types of radioactivity over two pages. Questions on alpha, beta and gamma radiation, nuclear decay, neutron emission and half-life. There’s a wide range of pictures and diagrams to jog students’ memory and the mark scheme includes links to videos of emitters from the IOP. This worksheet is especially targeted for the OCR 9-1 21st century science physics GCSE, although it could also be used for any other physics GCSE or secondary-level course. A version converted to black and white is included. (Update, 21/2/24: a misprint for the mass of alpha particles in the mark scheme has been corrected; my apologies about this.)

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.
