Practical Skills
There are three types of practical task all provided by OCR. Generally
tasks are 1 hour in length. They are done under exam conditions and
marked by your teachers.
1. Qualitative task [10 marks]
2. Quantitative task [15 marks]
3. Evaluative task [15 marks]
There are strict rules on how we administer these tasks. Make sure you buy
a white lab coat ready for September.
Holiday Homework
You have purchased a copy of Head Start to AS Chemistry. If you haven’t
got one go to the CGP web site or Amazon and order. It retails at £5 and
has an ISBN: 978 1 84762 116 0.
It recaps all the tricky topics from GCSE that AS builds on… so you won’t
have to! Ideal preparation for September no matter what GCSE option you
have followed. It will also be useful for reference throughout the course.
Holiday homework is to read and learn this book and come in
prepared for a test first lesson back in September:
Focus on the following:







The properties of sub-atomic particles
Ar (relative atomic mass) and Mr (relative formula mass)
Isotopes and calculations of average atomic mass
Calculating moles of solid
Electron arrangements and the Periodic table
The three types of bonding and simple bonding diagrams
How to work out the formulae of simple ionic compounds including use
of the five main compound ions: hydroxide, carbonate, sulphate,
nitrate and ammonium.
 Types of structure; giant ionic lattices, giant covalent structures
(especially diamond and graphite) and simple molecules.
Please do make sure you read the entire book.
Have a lovely summer…Mrs Lile, Mrs Faulkner, Mrs Cibangu and Mrs
