Grade 10 Chemistry
Pre-IB Curriculum Outline
(adapted from IB Chemistry SL)
Stuart Gilmer
Introduction
The Grade 10 Chemistry Pre-IB course encompasses carefully selected content from the Standard Level IB programme, with an emphasis on skills
acquisition in order to scaffold progression towards the IB Diploma in Grade 11/12. This course will advance pupils understanding of concepts in which
they should already be familiar with, working to develop the breadth and depth of knowledge to provide a solid preparation for the demands of the IB
Diploma programme.
Course Content Overview
As with Physics and Biology, the Chemistry course will run for 12 weeks and is split into three units; Unit One - Atomic Structure, Unit Two - Stoichiometric
Relationships and Unit Three - Chemical Bonding & Structure, details of each can be found on the pages which follow.
Assessment
Student knowledge will be assessed internally through homework and end of topic tests. Skills acquisition will be assessed through two experimental
reports and a homework assignment on “Using Elements in Industry”, which will be introduced during Unit Two.
Unit 1 Atomic Structure
Atomic theory lies at the centre of chemistry. The atom is the smallest unit of matter and it is from this building block that all living organisms and non-living objects are
made. In this unit pupils will look at; the structure of the atom as well as examining the theories and models that have lead to our current understanding and the
structure/arrangement of the periodic table.

Unit 2 Stoichiometric Relationships
The mole concept is fundamental to chemists, allowing a universal understanding in relation to the number of particles, mass and volume of a gas. Stoichiometry is
a quantitative method used to examine the relative amounts of reactants and products in a chemical reaction.
