Born-Haber Cycles and Lattice Enthalpy

Born-Haber Cycles and Lattice Enthalpy

(0)
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.

OCR science only: Checklist for A Level success

(0)
A Checklist for A Level success, most relevant to those studying OCR A Biology, Chemistry or Physics. (The links are to OCR 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 :)

VSEPR lesson

VSEPR lesson

(0)
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.
Calculations (step by step) for  unit 19 learning outcome A - Analyte determination

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.
Feasibility, thermodynamics, redox, reduction potentials

Feasibility, thermodynamics, redox, reduction potentials

(0)
This bundle includes an assignment brief (created by me), lesson on thermodynamics and feasbility (can be easily adapted for what level/content you would like to teach) and answers to the last 4 assignment questions. This was created for a level 4 course where I taught chemistry to biology apprentices (ages 18+). The title of the unit was ‘chemistry for applied biologists’ and this is one of 4 assignments set in that unit. It could also be used for A2 Chemistry as there are some worked examples and practice questions on Gibbs free energy and 2 redox practicals which include half equations and observations.

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.
Viscosity crossword and worksheet

Viscosity crossword and worksheet

(0)
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.

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
PAG 5.2

PAG 5.2

(0)
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.
A2 Chem conc-time graph worksheet

A2 Chem conc-time graph worksheet

(0)
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.
