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.

A test on chemical formulae that can be given to AS Chemistry students or students studying a level 3 science course that involves chemistry, e.g. will be useful for the new BTEC Applied Science Unit 1.
PowerPoint includes full list of ions that need to be learned in year 1 and also includes Roman numerals 1-10 which are often used in transition metal ions to indicate the positive charge on the ion formed.
Activities in formulae lessons (not included) include ionikits and ionikit worksheets (I think these worksheets are copyrighted and I’m not sure where they came from as they are quite old now).
A video I created to help students understand and learn formulae of ions. Explains from beginning what ions are, the general rules/trends and uses cards similar to the old ‘ionikits’ to illustrate the balancing of the charges. https://www.youtube.com/watch?v=pOsMci_o2dU
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 resource for Unit 5 Chemistry for A2 topic on the Level 3 Applied Science course
These can be printed and laminated to be done as a card sort
or they could be printed and used as a cut and stick activity

Alkene electrophilic addition mechanism worksheets
Created for #level3appliedscience #unit5chemistry but can also be used for #ASChemistry or any other #organicchemistry course
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.
