These student friendly handbooks are for the NEW AQA (9-1) Chemistry GCSE . These follow a similar layout and pattern I have used for the free revision and paid revision mats from my shop.
All required practicals from each science has 2 booklets for each exam for AQA.
Samples of the booklets can be found using the following link:
https://www.tes.com/teaching-resource/sample-new-aqa-science-required-practical-handbook-9-1-11945258
These include a how to guide for each practical, practical information and questions regarding the methods and techniques used in each practical. There is also graph paper included in this booklet. References for the ‘working scientifically’, ‘mathematical skills’ and ‘apparatus and techniques’ requirements for each practical.
