Unit 3 Fuels: Alcohol combustion practical and results

(0)
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
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.

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.

Chemical formulae test (with answer sheet!)

Chemical formulae test (with answer sheet!)

(0)
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
Unit 7 contemporary issues - full 2x double lesson

Unit 7 contemporary issues - full 2x double lesson

(0)
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
