Student (and teacher!) friendly assignment checklists for the first 2 assignments of Unit 18 (Industrial Chemical Reactions) in the Level 3 Applied Science.
I have created these using my own interpretations of the brief and teacher guidance.
Useful for teacher as can help speed up the marking process.
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 guide to PAG 9.1 suitable for students and teachers. This assumes a basic understanding of what is going on.
PowerPoint includes the lesson/PAG aims, what you should be recording, how to set up your apparatus (ie fill burette first and keep tap closed), how to calculate volume of oxygen and concentration of hydrogen peroxide.
PowerPoint also shows how your graph should look and what to include with your PAG submission.
The starting exercises at the beginning refer to the A2 textbook and the RSC starter for 10 worksheets which are readily available online: https://edu.rsc.org/resources/kinetics-starters-2-16-18/4010281.article
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.
A lab book created for Applied Science students studying Unit 2: Practical Scientific Procedures and Techniques.
This can be used as an electronic lab book to store results and calculations or can be printed and issued to students at the start of the unit.
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.
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.
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.
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.
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’ :)
Structured PowerPoints which can be used to structure your lesson and/or guide and help students.
Teaching videos (from me) on q=mc∆T and Hess’ Law https://youtu.be/BjbXJTB0JdA:

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.
