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.

Unit 3: Food as a fuel

(0)
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.

A2 Chem: acids, bases and pH.

(0)
This resource is a lesson created for A2 Chemistry OCR syllabus which covers Bronsted - Lowry acids and bases, conjugate acid-base pairs, mono, di and tribasic acids, neutralisation reactions with acid: carbonates, metal oxides and alkalis. Includes theory, is interactive and has questions and answers. It has step-by-step guides to calculations and refers to OCR Chemistry textbook (states page numbers of summary questions to complete at end of teaching a mini-topic). Watch me teach the basics of part this topic at ‘PhysChem with Liz’ on YouTube: weak acids (calculations): strong acids (calculations): https://youtu.be/NTEa1sBThRg
A2 Chem PAG 9.1

A2 Chem PAG 9.1

(0)
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
Unit 19 Spectroscopy - Introduction and Infa-red spectroscopy

Unit 19 Spectroscopy - Introduction and Infa-red spectroscopy

(1)
I created this lesson for the new unit 19 level 3 applied science, assignment B, spectroscopy. This lesson lasts about 1.5 hours including completion of activities and introduces the students to spectroscopy by recapping the electromagnetic spectrum (I have also included some points in the notes section of the powerpoint which you may wish to discuss). The data sheet I used with my students was the OCR A A Level Chemistry one (just what was handy in the lab) and the PowerPoint refers to worksheet A which is part of their assignment. This can be found on the Pearson website, along with answers. I have included a link to a video I created introducing IR spectroscopy, aimed at students :) https://www.youtube.com/watch?v=XxYTIuKYbvc

AS Analysis past paper questions

(0)
Mixed past paper questions on this topic (infra-red, mass spectrometry and elemental analysis) from OCR A which are readily available on past paper finder (still suitable for use for those studying other exam boards). Suitable for AS students. #infrared #massspec #elementalanalysis
AS Revision Board Game

AS Revision Board Game

(0)
AS Module 2 Revision Board Game on bonding, structure, properties, shape, electronegativity and polarity. Students really enjoyed playing this game and it was an excellent way to revise. Teacher will need: scissors, printer, card or a laminator (so the playing cards last), counters (1 per student), dice (1 per group). Included: cards for 1, 2 and 3 point questions with Qs and As blank versions of cards for 1, 2 and 3 point questions so you can adapt/write your own board game About: This is a learner-led revision activity. Recommended group size per board game: 4 Estimated time to complete game based on this group size: 50min - 1 hour (based on experience and length of student engagement). Game can be any length of time as winning is based on number of points rather than reaching the end of the board. Rules: Class to be split into roughly groups of 4 Each group to be given 1 board game mat, 4 counters, 1 dice and a set of 1, 2 and 3 point Q cards. They also need scrap paper and pens/pencils for working out Each group can either nominate a reader for the Q cards or they may take it in turns to read. #bondingstructureproperties #ASChemistryrevisiongame #Chemistryrevision #VSEPRrevision

Plant chromatography method + Qs (with answers)

(0)
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. #plantchromatography

AS Chemistry revision overview workbook

(0)
Overview of AS Chemistry revision workbook. Answers attached. Useful for students to have a go at independently using their textbook and class notes, or from memory closer to the exam/mock. Teachers may also wish to use this during revision sessions together with past paper questions. Include examiner comments at the end which state how to do well on breadth and depth papers. #ASChemistryrevision #ASChemistryoverview

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.
Yoga, meditation and other stress management techniques

Yoga, meditation and other stress management techniques

(0)
I created and wrote this booklet and delivered a session (lasts around 45min-1 hour depending which yoga sequences and meditation you choose to do) to a cohort of stressed out trainee teachers and staff just before the Christmas break. The session was well received and had excellent feedback with several people saying they found it really helpful. The booklet starts with assessing your level of stress, looking at how you spend your week (divided into 30min sections) - this is a good opportunity to discuss and be able to visualise work-life balance. The booklet then takes you through many ideas for stress management techniques, with a couple of mini activities including a page introducing the concept of a gratitude journal and a ‘meditation challenge’. At the end are some books, apps, journal articles and contacts in case people wish to find out more.

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 :-)
