Unit 6 student checklists, action plan and project proposal structure

(0)
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.

BTEC L3 Applied Science: Introduction to Unit 7 Contemporary Scientific Issues

(3)
Attached is a full introductory lesson created for the new BTEC Unit 7: Contemporary Scientific Issues. It is activity based, with instructions and answers, a recent case study to get students started, points for discussion, a video on the case study, explanation of terms ethical, environmental, social and economic along with reliability and validity. Gets students thinking about reliability of sources, bias, etc. Homeworks during the first few months of teaching (and tutorial sessions, if you have these) could include watching documentaries on scientific issues to broaden student’s knowledge of contemporary issues in general. You may wish to select these yourself (from Netflix, Youtube etc.) or ask the students to find 1 each for homework and bring to next lesson (to minimise your workload!) then you can decide which to watch as a class and use as a point for discussion etc. Link to video introducing Unit 7: https://www.youtube.com/watch?v=AMFkvxYIVfU
Unit 4 Assignment B - ethyl ethanoate

Unit 4 Assignment B - ethyl ethanoate

(0)
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’ :)
NEW L3 Unit 2 Applied Science: sample results

NEW L3 Unit 2 Applied Science: sample results

(0)
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. supporting videos for assignments: A plotting and annotating pH curve: https://youtu.be/mgNhkUipZw0 Plotting and annotating colorimetry curve: https://youtu.be/IXXOmPygKXY Writing chemical foon a computer: B plotting cooling curves: https://youtu.be/92zysOBqKP8 Finding and referencing a literature value: https://youtu.be/b4jkipDtO9k Drawing a tangent to a curve: https://youtu.be/Ne-cxsjHPIM 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.

NEW L3 Applied Science Unit 19 - PRACTICAL - nitrate from soil UV spectroscopy

(3)
Attached is a full lesson 5 page worksheet containing a detailed step-by-step method (including how to use the UV-vis), introduction including theory on Beer’s Law, space for students to tabulate and record their results, questions around the topic, answers and sample results. There are a couple of photographs (taken by me when I was trialling this) to help students visualise how things should look when they are carrying out the method. This can take around 1 hour - 2.5 hour lesson depending on equipment availability and how you wish to deliver it. :-) Please leave a review!
A2 CHEMISTRY - PAG 10.2 + 9.3 RATES

A2 CHEMISTRY - PAG 10.2 + 9.3 RATES

(0)
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.

Calculations (step by step) for unit 19 learning outcome A - Analyte determination

(0)
Attached are step-by-step calculations with equations, ratios, units etc which were created for the new unit 19 in the level 3 applied science course (new from 2016). The calculations are for the determination of bicarbonate in bottled water, the amount of copper in brass and the amount of iron in iron tablets. There are 3 stages to the bottled water practical, the end answer states the concentration of bicarbonate in water (tap water was used to save money!) in moles per decimetre cubed.

U19 Applied Science AsB help for teachers - Quantitative IR spectroscopy

(1)
Some pointers and ideas to help you devise a method and practical for the new unit 19 applied science unit. This practical is one of the 4 options for assignment B. I know that the use of IR for quantitative analysis is uncommon, but it can be done. Find attached a journal article of a similar experiment and a short outline of a method (word doc). Journal is obviously not my own work, I have just uploaded these to help centres devise their own methods for this assignment. I hope this is helpful for you. Please take a look at my other resources :-)
