Method, with link to useful YouTube video demonstrating the practical. Practical-based Qs testing students understanding of the steps in the method, answers at bottom.
Slightly different method for stretch and challenge - can run more than 1 chromatogram simultaneously and some extra Qs at the bottom relating structure to Rf value.

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 Checklist for A Level success, most relevant to those studying AQA Biology, Chemistry or Physics. (The links are to AQA resources and answers)
I have 9 years experience teaching the A Level and my colleague has over 30 - together we have noticed and written down the most effective ways for science students to revise and see the fastest and biggest improvement in their grades. This information is provided in a student-friendly checklist format :)

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
Sample results for practical-based assignments A, B and C for Unit 2 Practical Scientific Procedures and Techniques.
Includes results for calibration of 3 pieces of equipment, 2x titrations (one using indicator, one using a pH probe) and colorimetry for assignment A.
For assignment B includes results for calibration of a glass and digital thermometer in hot and cold water and cooling of both stearic acid and paraffin wax.

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.
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 viscosity worksheet on identifying Newtonian and non-Newtonian fluids and a crossword which can be used as an end of topic/end of lesson activity. Both with answers!
Created for Level 3.
A PowerPoint created for teachers on how to structure the lesson and key things for students to notice. Includes a starter activity and some pointers about citing values, the 2 layers in the separation stage and how to do the yield calculation.
Note that PAG methods and teacher/technician sheets are on the OCR website. Each institution should have one person who is given an OCR login and access to these.
The brief for learning aim A was not provided by Pearson, so this was written by me for assignment A of Unit 19.
Includes brief template, scenario and all criteria and tasks (ie write a PowerPoint to include… and create a typed document to include…).
NOTE -** this resource does not include practical method sheets/instructions.**
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.
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 nice 5-10 minute activity where students sketch and describe the shape of the graph and how k can be found.
Ideal for a starter/plenary.
I have included an answer file too. Ignore my first and second order curves, badly drawn! Second order should be steeper at the start compared to first order.
The first assignment’s lessons planned out and timing of delivery of the other two.
Written in a SOW format. Could be used as lesson plans (depending what you and your centre require). :-)
Laboratory design activity that could be used for an after school STEM club, mini science project, summer project or even a class task. Aimed at school level but can be as simple or challenging as you would like to make it :)
A supporting PowerPoint is attached with ideas for student instructions ie group tasks visiting laboratories, what to focus on/take notes + photos of. This can be quite hands on and you can let students measure things and do conversions, creating keys and grids in their own laboratory design plans, if you have the facility to do so.
Starter worksheet (cloze passage) created for the new L3 Applied Science (from 2016) Unit 3 (I used this for an observation). To recall previous knowledge on fuels. Includes stretch and challenge/early finishers task at the bottom and task objective at the top.
Main lesson task also included which guides students through how to structure and what to write and include for a lab report.
Organic mechanisms worksheets + answers
nucleophilic substitution, nucleophilic addition, addition-elimination and elimination.
Students are given the steps describing each mechanism and they have to put them in the correct order.
Answers included.
Suitable for A2 Chemistry students or applied science students studying #unit14chemistry
