Worksheet as a reminder of how the ideal gas law works, showing all the unit conversions and with a model calculation. Also includes a diagram of why a cubic metre = 1 million cubic centimetres, something students often have trouble with. Suitable for all A-level chemistry and 16+ exam boards e.g. AQA, Edexcel, OCR, Cambridge. The assumptions the ideal gas law makes are also explained.

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.

Five page revision notes on Gibbs free energy, for the OCR A specification. Covers the standard trick questions, graphs against temperature, and includes a range of worked examples, diagrams of the graphs, types of reactions where ΔH and ΔS have different signs and unit conversion examples.

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.

Flow diagram showing the menstrual cycle on one page. Suitable for AQA 9-1 GCSE, Edexcel 9-1 GCSE, Edexcel iGCSE and Cambridge iGCSE exam boards, among others. Clean modern design, easy to follow. Explains roles of follicle stimulating hormone, luteinising hormone, oestrogen and progesterone, the pituitary gland, ovaries and corpus luteum. I have a separate version for OCR Gateway GCSE science-that course has slightly different content.

Worksheet covering wave speed, frequency, and wavelength, on two pages, targeted for OCR 21st century science 9-1 GCSE physics. Intended to provide a graduated scheme of work from definitions to calculations of wavelength, frequency, wave speed, period, longitudinal and transverse waves and taking in unit conversion. There’s diagrams and power triangles for the two core equations for the student to practice using and a mark scheme.

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 Edexcel 9-1 physics iGCSE, although it could also be used for any other physics GCSE or secondary-level course. A version converted to black and white is included.

Worksheet covering the types of radioactivity over two pages. Questions on alpha, beta and gamma radiation, nuclear decay, neutron emission and half-life. Based on review of past paper questions, I’ve found knowing exactly what blocks different types of radiation is a key topic for practice and there’s a lot of questions on this. There’s a wide range of pictures and diagrams to jog students’ memory, and I mention alternative ways of writing the decay equations. This worksheet is especially targeted for the AQA 9-1 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. Model answers are based on collation of many past paper questions, giving extensive exam tips. Want to know exactly what definition of gamma radiation AQA want? It’s on page 2 of the mark scheme. 2024 updates: links to videos of emitters from the IOP and using beta particles are included on the mark scheme and a wrong number for charge has been corrected.

Worksheet covering the types of radioactivity over two pages. Questions on alpha, beta and gamma radiation, nuclear decay and equations 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 Edexcel 9-1 science physics GCSE, although it could also be used for most other physics GCSE or secondary-level courses (I have versions for other exam boards). A version converted to black and white is included.

A-level osmosis required practical notes, targeting courses including AQA 3.2.3 and required practicals 3 and 4 and OCR A 2.1.5. The notes include diagrams on how to plot a graph of the data and some exam technique practice on how to answer questions on getting valid data, and links to good videos. The notes are bullet point style and easy to read. This set of notes is particularly targeted towards revising the practical come exam time and doesn’t include a detailed practical methodology. NOTE: my apologies, the original uploaded version had some words missing explaining the effect of evaporation on water potential, this has now been corrected.

One page revision notes for AQA explaining the idea of error bars. I include model answers for a range of types of question and explanation of what p < 0.05 means. I list a couple of past paper questions which have good questions to practice from, all from the current specification. AQA want you to say that differences are significant if error bars don’t overlap, even though in reality it’s more complicated than that. I clearly explain this and say that this idea shouldn’t be used if students go on to degree-level statistics. Questions and mark schemes consulted in writing these notes included: significant difference: 74022 2020 2.4 differences that are not significant: 74012 2019 1.2 range error bars: 74023 2017 2.5 no error bars: 74022 2020 7.2 probability and chance: 74021 2019 4.4 Update, 2024: Following feedback from a student, added scale to clarify that the error bar shows mean ± SD. Clarified that the comments on probability/significance are when comparing means (so e.g. wouldn’t apply to the chi-squared test).

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.

Worksheet on making copper sulfate crystals from copper oxide (insoluble base method) covering two pages for Edexcel 9-1 iGCSE chemistry, versions in colour and in black and white for printing with a mark scheme. Covers removing the excess copper oxide and letting crystals form. There’s a link to a recommended video from Pearson. The content is divided over the two pages: the first page is more “directly on the topic” questions and could be used on its own for students at the time they cover copper sulphate or do the practical, the second page is more extension and for “final exam revision”: based on student questions and points that came up from discussing the video, I made the second page cover more synoptic questions making connections with other topics, like temperature and rate of reaction. The worksheet is targeted towards building exam technique and written question skills, so doesn’t include a full practical method. Questions consulted include 2C June 2016 Q7 for technique (I recommend this for exam-style practice) and 1CR June 2019, question 5d for rate of reaction and temperature. I have a similar worksheet for AQA GCSE chemistry.

Worksheet on homeostasis and thyroid function, covering thyroxine, TSH and homeostasis and negative feedback generally. This two-page worksheet has plenty of illustrations and diagrams to help students remember the topic and case-study questions. There’s an in-depth mark scheme and versions for colour and black and white printing. Targets the OCR twenty-first Century Science 9-1 GCSE Biology course. I also have versions for AQA GCSE biology and Edexcel GCSE biology.

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.

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.

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.

Notes on purifying an organic liquid, including links to RSC YouTube clips of the processes. These notes are oriented towards exam technique and don’t include a complete practical method. The notes are particularly targeted towards the AQA chemistry A-level and required practical but could be used for other courses or as a basis for other lesson plans. 2018 AQA paper 3 question 3 was consulted writing the notes.

Image on how people can stop and slow down climate change using vivid photos from around the world. As four answers, I’ve chosen four things that children can realistically do themselves: avoiding using cars, using energy less like heating and air conditioning, recycling and eating less meat and dairy products. There’s also a version with blank spaces for students to fill in their answers. Useful for geography, chemistry and science, plenary and general citizenship lessons. If your teaching prefers the wording “climate change” rather than “global warming”, I also have a poster saying this, content is otherwise identical.

You get a much better response explaining cyclic AMP when you draw it as a hat that makes enzymes happy when they wear it! One-page revision notes on cAMP for the AQA specification, with links to YouTube videos of some of the processes discussed. I am thinking of expanding this into a more full set of notes including details of the adrenaline receptor and with more diagrams-please comment if that’s something you’d want. It’s offered for free in the meantime.
