This is end of Module 2 Assessment which has been typed up from inside the OCR textbook as there was no electronic version available. This covers all of the topics below:
Atoms, compounds, molecules and equations
Amount of Substance
Acid-base and redox reactions
Electrons, bonding and structure
This assessment includes a range of multiple choice and longer answer questions to get students ready for the summer exams. Spaces can be typed in for students to write under the questions or they can also answer on another piece of paper. The corresponding markscheme is available as well.
I use this at the end of Module 2 to inform progress before larger assessment week exams.

Second Lesson I use as part of the topic Atomic Structure and Isotopes in Module 2 - Foundations in Chemistry.
The lesson reviews Isotopes and ions from the first lesson then goes onto relative isotopic mass and relative atomic mass. It also covers how to identify an element from its mass spectrum and calculating RAM.
OCR new spec does not need to know how a mass spectrometer works but I have some basic information in there to help understanding of what happens.

This is the fourth lesson in the Amount of Substance topic in Module 2 - Foundations in Chemistry.
After PAG 1.3 has been performed I teach this lesson. The powerpoint covers moles, volume and concentration calculations and re-arranging the equations. converting between units and making up a standard solution using equations.
The worksheets help practice equation and calculation practice and there is a practical sheet for making up a standard solution for students and teachers.

These are lessons 7 and 8 in the Amount of Substance topic in Module 2- Foundations in Chemistry.
The Stoichiometry powerpoint covers how to use the molar ratio to calculate an unknown and various examples using the equations taught in the topic so far with various degrees of difficulty and answers. I often mount these onto card with the answers underneath around the room to encourage discussion and group work.
The yield and atom economy powerpoint covers how to work out % yield and atom economy calculations as well as comparing the difference and which is more favourable.
