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 for AQA A-level biology plant tropism on two pages, covering IAA, phototropism, gravitotropism, the acid growth hypothesis and an experiment design question. Versions for colour and black and white printing and a detailed mark scheme. Written for the new 2015 specification.

Worksheet covering wave speed, frequency, and wavelength, on two pages, targeted for AQA 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. There’s diagrams and power triangles for the two core equations for the student to practice using and a mark scheme. Particularly suitable for 1:1 tuition. Questions consulted include 8463/2H 2021 Q5, 84652H 2020 Q5 and 8464/P/2H Q3. Update, June 2024: following feedback from students, I decided that including unit conversions in the worksheet made calculations too long, so removed this, also put power triangles on both sides of the worksheet to make them easier to find.

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.

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.

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 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.

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 on capture mark, release and recapture population estimates, suitable for courses including A-level biology and Edexcel GCSE statistics. Covering one page, the assumptions and the idea of a reciprocal are explained and there’s two model calculations.

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.

Some of the hardest questions for many GCSE chemistry students are the long answer written questions, explaining things like why the rate of reaction increases when you increase the temperature, and how the position of equilibrium shifts.

A version with colour pictures is included. 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. This set of notes was written against the current AQA GCSE science specifications. Past paper mark schemes consulted include: ionic bonding: 4.3 from 8464/C/2H, 2018, specification reference 5.2.2.3. giant covalent bonding: 5.1 from 8464C1H 2018, specification reference 5.2.3.1 3.4 from 8465/3H 2019, specification 4.8.1.1 simple molecular bonding and intermolecular forces: 4.4 from 8464/C/1H 2019, 5.1.2.6 and 5.2.2.4 7.1 from 84644C2H specimen, 5.2.2.4 concentration and rate: 5.5 from 8464/C/2H 2019, specification reference 5.6.1.3 temperature and rate: 6.4 from 8465/3H 2019, reference 4.7.4.3 metallic conductivity: 2.6 from 84643C1H specimen paper, reference 5.2.1.5/5.2.2.8 equilibrium: 4.3 from 8465/3H 2019, 4.7.4.8 4.7.4.10 7.2 from 84644C2H specimen, 5.6.2.4

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.

Simple worksheet on two pages covering electrolysis of aluminium for students to fill in. Covers the equations at the cathode, anode, redox, why the process is environmentally damaging and why recycling aluminium is a good thing to do. There’s also links to recommended YouTube videos from Fuse School and the RSC. This plan targets the Edexcel iGCSE 9-1 course. Versions both in colour and black and white. This lesson plan is given away for free in order to encourage recycling! But if you like it please check out my lesson plan on metallic bonding and other lesson plans. I also have versions of these questions for Edexcel GCSE and for AQA. Update: 16/3/24: added clarification that the cathodes are graphite and added a link to a video showing bauxite mining to show the amount of land needed.
