Includes amino acid and plant chromatography for assignment C.
Note amino acid was paper chromatography and basil was used for the plant chromatography, which was thin layer chromatography.
Solvents used for chromatography were as follows: For the amino acid chromatography we used a mixture of solvents in the following ratio: butanol, water and ethanoic acid in 4:2:1, respectively.
For the plant chromatography we used a mixture of solvents again, in the following ratio: cyclohexane, acetone and petroleum ether in 5:3:2.
This is a booklet I’ve put together for anyone interested in doing a little ‘at home virtual yoga retreat’! You can do it alone, with your children or partner, it’s up to you.
if you are new to yoga and/or meditation, you can check out my other resource ‘Yoga, meditation and other stress management techniques’ which may be good to start with
I have included online guided yoga and meditation videos for each day (with a range of instructors, so you may find someone new you wish to subscribe to or in case you prefer some styles of teaching over others!). I have also given each day a theme and included some journalling prompts. Please let me know what you think in a review :)
I will be updating the booklet as I continue adding to it, but wanted to get it uploaded asap for anyone looking for ideas of things they can do at home. Let’s try and make the most of this time :)
PS - I’ve also included a yoga/meditation calendar for May which is from ‘YogaWithAdriene’ (not made by me) x
A PowerPoint lesson for Unit 4 assignment B preparation of an organic liquid. Includes lesson plan, helpful videos, pre-practical questions and starter activity worksheets (with teacher answers). I was observed in this lesson and obtained good feedback.
Includes a worksheet to assist with ideas and a starting point for research tasks/discussion around P4.
Other details: While students are refluxing for 30min, you could get them to look up literature values for the boiling point of the ester (so they know the temperature it should come out at during distillation) and research factors that affect purity and the effect that impurities will have on the boiling point. What are possible impurities and where may they come from etc.
If you have efficient, confident students, this full lesson with the 3 stage practical including activities will take 3 hours. If your students are less confident, I recommend 4 hours.
**note - **recommended videos included are from the RSC
written lesson plan is mine, however the template is from ‘teacher toolkit’ :)
Link to (the familiar!) real world with the question: does adding sugar to tea cause it to cool down?
An informative and step-by-step PowerPoint which guides students through the steps and knowledge involved in constructing a Born-Haber Cycle and calculating lattice enthalpy. Explains why a B-H cycle is used and what lattice enthalpy tells us. Refers to worked examples, questions and exam questions from OCR A syllabus so is ideal if you have a class set of the OCR textbooks too.
Stretch and challenge is (and can be further) incorporated by examples using compounds made of ions with different charges, e.g. alumina.

This includes a mini selection of resources including a crossword on learning aim G (fuels), an independent task where students can get on with preparing presentations on the hazards of fuels (has a checklist, 4 choices of what to present on and is differentiated), a results table including structured calculations and report template, a glossary which can be used throughout and added to each time a new key term is introduced and a scientific investigation card sort (which can be used at the beginning as part of the introduction to the unit).
A booklet covering an intro to buffers, all the equations you need to learn and the main types of buffer calculations with stepwise methods and an answer booklet with all working.
This PowerPoint is most useful for new teachers, teachers who have not taught VSEPR before (ideas for how to structure your lesson) or teachers who want ideas on how to make this topic more interactive and include ideas for kinaesthetic activities.
This PowerPoint includes VSEPR yoga, VSEPR triominoes (I have not included the resource as it is a pack of cards, however I have included instructions and an image example so you can make your own) and VSEPR cut and sticks can also be made to keep your students engaged.
Other interactive ideas could include online quizzes such as Kahoot, Bingo etc.
Designed for Unit 2 Practical Scientific Procedures & Techiques L3 Applied Science.
Lesson activity for part of Assignment A teaching and completed ‘5 min lesson plan’
Credit to ‘teacher toolkit’ for the format of the lesson plan.
A ‘fun’ resource to check your student’s learning on redox and oxidation numbers.
These domino cards can be printed on card/paper and then laminated (especially if printed on paper).
Available in blue and creamy yellow for students with dyslexia.
This is a lab book for unit 2 that will help students greatly once assignments are issued. Students can record their results in here during/after the practicals, either handwritten on a printed version or typed on an online copy.
This saves loads of time with planning lessons :-)
I hope that you find it helpful.
These sheets were created for a class that fell behind and were struggling with unit 4.
2 fool-proof sheets for B and C handy for when students need to finish asap
Created for A Level Chemistry and suitable for all exam boards.
Can also be used on any course that studies benzene and looks at it’s stability compared to that of the Kekule structure.
A booklet that can be done for homework or in class to help consolidate the theory from learning aim G. Includes possible exam questions that may come up in the Part B written paper.
Questions and answers
Designed for AQA A Level Chemistry but can be used for any other course on which students need to understand stereospecificity in enzymes
A resource created to assist teachers and students with delivery of the A2 OCR Chemistry PAGs.
A PowerPoint to help you structure the beginning of the PAG lesson on 10.2 thiosulfate and acid. Can easily be amended and used as a template if preferred. Alternatively, this could be given to students as a guideline to assist them with their planning and calculations.
Example results and graph for thiosulfate (part 1) included, showing the first order relationship.
Possible extension opportunities include monitoring how temperature affects the rate of reaction - an Arrhenius plot could then be done as part of the analysis. Recommended for A-A* students.
Gives students a checklist of what needs to be submitted.
PowerPoint for PAG 9.3 rates attached also. This one includes OCR past paper questions (and answers) at the end as a plenary.
A powerpoint presentation (consisting of activities and answers and a link to the RSC video on NMR) and worksheet (comic strip to help students condense information and remember the main points of NMR) to assist teaching with the new L3 Applied Science Unit 19.
This was created to help teach NMR spectroscopy. It has activities throughout and is step-by-step, I have simplified where possible.
Has a couple of extension/early finishers activities in.
I have created a series of 3 videos in which I teach NMR, the first can be found here and is about chemical equivalency :) https://www.youtube.com/watch?v=-fWA108hr8M
Attached is 2 double lessons (4 hours) worth of activities, lesson is interactive, student-led, exam-focused.
Prior to this, students should choose a contemporary scientific issue of their choice - this can be from a magazine eg New Scientist or Chemistry Review etc. or from online.
They can produce a little written piece introducing this if you wish them to.
The teacher can then go through the PowerPoint regarding part B of the exam -this PowerPoint explains the structure of part B of the exam and describes what to include and how to structure your answers in order to achieve high marks.
In some cases, ideas of how to start answers are given.
Students should answer each of the questions (except the last one) for THEIR chosen contemporary issue (see peer assessment form for how to do this in presentation style. This can be done in a presentation format and communicated to the class, during the presentation, the presenter will be assessed by their classmates using the peer-assessment form attached.
Many skills are addressed in this lesson(s), such as communication, critical thinking, analysis, detecting bias, independent research, ability to give and receive constructive criticism, drawing valid conclusions, making sensible judgements, simplifying complex issues and interpreting graphical and statistical data etc.
