Notes and diagrams on epigenetics for the AQA course, starting from some simple analogies to the real world. I also give the core definition AQA have asked for of epigenetics, which isn’t clearly stated in the textbook but came up on a specimen paper. There’s links to tons of YouTube videos explaining how epigenetics works, and a mnemonic for remembering euchromatin and heterochromatin. Length is two very well-filled pages: you could print it double-sided as a resource for students to keep. Could also be useful for students taking OCR as extension material.

One-page set of notes on differential ultracentrifugation to extract organelles, covering homogenization, the ice-cold, buffered, isotonic solution, extracting different organelles and links to recommended videos. This set of notes is particularly targeted towards revising the practical come exam time-it doesn’t go into a detailed practical methodology for fractionation but gives exam-oriented explanation of how a centrifuge works, what a cold, buffered, isotonic solution is and why it’s needed. These notes should be suitable for all major A-level courses, but they’re particularly designed to help AQA students taking into account points on the mark schemes for the 74011 specimen paper Q1, 74023 2018 Q5 and 74011 2018 Q7, which would be great for practice alongside these notes.

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 AQA 9-1 chemistry GCSE 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, my worksheet on AQA solution electrolysis equations and on extracting metals using carbon and other lesson plans. I also have versions for Edexcel GCSE and Edexcel iGCSE. Update: 13/3/24: added clarification that the cathodes are graphite and added a link to a video showing bauxite mining to show the amount of land needed.

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.

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.

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.

Two-page link-up-the-boxes worksheet and two-page written worksheet recapping definitions of community, habitat, ecosystem and biotic/abiotic factors, along with case study questions. For the Edexcel 9-1 biology GCSEs. The link-up-the-boxes worksheet is deliberately written to be very easy for students with low knowledge and confidence. The written worksheet covers biotic factors, quadrats, transects and competition, along with a calculation question and practice identifying types of habitat. Versions for colour and black and white printing and a mark scheme are included. Could also be suitable as a quick recap exercise for A-level students. These worksheets are very similar to my set for AQA, if you tutor both courses you don’t really need the other version. For the Edexcel iGCSE, I intend to do a version of this worksheet specific to that course in future, but for now this worksheet is fine to use; a few questions (10 and 11 on the written worksheet, 3 on the link-the-boxes worksheet) aren’t things students need to memorise but those questions would still be fine for students to do as “suggest” questions.

Worksheet on one page on when you use less and when you use fewer. Versions both in colour and black and white and a mark scheme. Colourful design with emoji graphics for each question to make it more enjoyable.

Worksheet on homeostasis and thyroid function, covering thyroxine, TSH and nutrient deficiencies as well as revising homeostasis and negative feedback generally. This two-page worksheet has plenty of illustrations and diagrams to help students remember the topic. Targets the Edexcel 9-1 biology GCSE. There’s an in-depth mark scheme and versions for colour and black and white printing. Doing AQA? I have a separate version of the worksheet for the AQA course. Doing the Edexcel iGCSE? This worksheet isn’t needed, that course doesn’t go into so much depth on the topic. 2024 update: following feedback from students, added more space for answers.

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.

Two-page worksheet and mark scheme on the use of positron emission tomography scans in medical imaging of the brain and cancer, a topic on the current Edexcel biology GCSE, with a range of diagrams, pictures and links to recommended videos. The worksheet is also suitable for teaching in physics as a case study. Worksheet assumes a bit of basic knowledge of radioactivity and gamma rays (safety precautions, hazards) so may be worth coordinating with physics that those topics have been covered, although it’s only at a common sense level of knowledge. Specification reference: brain and spinal cord problems, B2.11B and B2.12B, higher tier.
