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. YouTube videos: Introduction https://www.youtube.com/watch?v=oLGUA_EssMY&list=PLaD6fcqFKTWju1PsWNzEjMXZ3bCJ32ikf&index=13 Worked example for NaCl: https://www.youtube.com/watch?v=kjkdsaP8fPA&t=39s Worked example for MgCl2: https://www.youtube.com/watch?v=OUgKByeZg0c&t=48s

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 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

Attached is 2 double lessons (4 hours) worth of activities, lesson is interactive, student-led, exam-focused. Prior to this, students should choose a contemporary scientific issue of their choice - this can be from a magazine eg New Scientist or Chemistry Review etc. or from online. They can produce a little written piece introducing this if you wish them to. The teacher can then go through the PowerPoint regarding part B of the exam -this PowerPoint explains the structure of part B of the exam and describes what to include and how to structure your answers in order to achieve high marks. In some cases, ideas of how to start answers are given. Students should answer each of the questions (except the last one) for THEIR chosen contemporary issue (see peer assessment form for how to do this in presentation style. This can be done in a presentation format and communicated to the class, during the presentation, the presenter will be assessed by their classmates using the peer-assessment form attached. Many skills are addressed in this lesson(s), such as communication, critical thinking, analysis, detecting bias, independent research, ability to give and receive constructive criticism, drawing valid conclusions, making sensible judgements, simplifying complex issues and interpreting graphical and statistical data etc. Link to video introducing Unit 7: https://www.youtube.com/watch?v=AMFkvxYIVfU

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
