Lesson
Learning Outcomes

Lesson 1
Solids,
liquids and
gases

Activities
understand the

arrangement, movement
and energy of the particles
in each of the three states
of matter: solid, liquid and
gas

understand how the
interconversions of solids,
liquids and gases are
achieved and recall the
names used for these
interconversions
 explain the changes in
arrangement, movement
and energy of particles
during these
interconversions.
Review work on Particle
Theory from KS3. MORE
depth required here for
GCSE – see below.
Students draw diagrams of
particles in the three states
of matter and label with the
processes to change from
one state to another.

Demonstrate sublimation of
iodine and discuss what is
happening to the particles.

Ask pupils to describe what
happens to particles in
melting ice and boiling
water. This could be a peer
assessment activity, ask
students to use the
following ideas in their
explanations, energy, speed
forces between particles

Discuss changes in energy
related to the degree of
movement of particles
associated with each
change of state

Balancing
equations
Learning Outcomes
 write word equations
and balanced chemical
equations to represent
the reactions studied in
this specification
 use the state symbols
(s), (l), (g) and (aq) in
chemical equations to
represent solids,
liquids, gases and
aqueous solutions
respectively

 Learn diatomic
molecules and
formulae of
groups and
their valency.


Practice formulae – some
examples
CaCl2 NaNO3 CuSO4 Na2SO4
NaOH Ca(OH)2 Al2O3 (NH4)2SO4
Explain the use of brackets and
be clear on the use of groups
without breaking them up.
Review diatomic molecules from
yr 8, hydrogen nitrogen, oxygen,
fluorine chlorine, bromine iodine,
astatine. Explain the importance
of these in balanced equations.
Introduce balanced equations by
counting atoms on each side of a
simple equation.
Lesson 4 – review homework
Introduce state symbols and
incorporate in balanced
equations
Practice more difficult equations
from worksheet, writing formulae
first.

Lesson 6




Atoms,
elements
and
compounds

understand that atoms
consist of a central nucleus,
composed of protons and
neutrons, surrounded by
electrons, orbiting in shells

recall the relative mass and
relative charge of a proton,
neutron and electron

understand the terms atomic
number, mass number,
isotopes and relative atomic
mass (Ar)
(Isotopes are studied in the
Mole topic)
 understand that the Periodic
Table is an arrangement of
elements in order of atomic
number

 All atoms of a particular
element have the same
number of protons. Atoms of
different elements have
different numbers of protons.
 Candidates are expected to
be able to calculate numbers
of each sub atomic particle
from its atomic number and
mass number

Periodic Table activity
Pupils colour and label a
Periodic table to show groups
periods, metals, non metals,
and to gain an appreciation of
the symbols of elements.
Discuss and review the
diatomic elements from KS3.
Structure of the Atom
Introduce sub atomic particles,
and discuss the structure of
the atom, complete a table of
sub atomic particles, as in
AQA spec, include relative
mass.
Introduce Atomic Number,
Mass number and their
relationship with sub atomic
particles.
Introduce electron structure
and start to complete atom
viewer w/s. Introduce electron
configuration
Review Periodic Table, use e
science resource, table

Learn symbols
and for all
elements up to Ca,
plus Cu Fe, Zn,
Ag, Au, Br, Pb, I
Test this
knowledge as

Lesson 7
Electron
Structure
 In an atom, the number of
electrons is equal to the
number of protons in the
nucleus. Atoms have no
overall electrical charge.

deduce the electronic
configurations of the first
20 elements from their
positions in the Periodic
Table
 deduce the number of
outer electrons in a main
group element from its
position in the Periodic
Table.
