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.
Here are 4 sets of sample results that students can use to practice the calculations or in case they lost their results.
There is also a video which they can follow along with as a guide while they do their calculations, which explains each step: https://www.youtube.com/watch?v=kb3f_9rxcac
The other document is a task list, which tells the student step by step how to structure their report (what headings in which order), where to put their results and where to follow along with the video :)
This resource is ideal for an online lesson or cover lesson task.
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.
I created YouTube videos with instructions and activities in, a demo of the practical and results that students can use to analyse. I also explain and guide them through the calculations:
Risk assessment: what and how to and guides students through how to write their own and what to include https://www.youtube.com/watch?v=6XRQfdqygTk&t=10s
Practical: includes explanation, demo, activities throughout - how to write up and structure a lab report and how to tabulate results and do the first lot of calculations https://www.youtube.com/watch?v=8NqUFSO5Ck0&t=199s
Method attached
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 student-friendly checklist that is not overwhelming. This was created for Unit 6 Investigative Project Assignments A, B and C/D. These are preliminary checklists to get students started and on the right track.
Checklist for P, M and D criteria for assignment A and just P criteria for assignments B and C/D.
I have also made 2 short summary videos which may be helpful for students or new teachers; one is an intro to what Unit 6 is about https://www.youtube.com/watch?v=3gVKhB_3jiM and the other is aimed at students and explains how to get started with the literature review in assignment A. https://www.youtube.com/watch?v=7r-dWTxqI9M
Audit and action plan template also included, along with a suggested structure for the project proposal.
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
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’ :)
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.
