Introducing the particle
theory
• Determine prior knowledge
of states of matter
• Distinguish between the
properties of solids, liquids
and gases in terms of shape
and volume
Measuring phase changes
(Lab)
• Conduct an investigation to
measure phase changes
• Analyse the results to
determine the melting point
and boiling point of a
substance
Comparing boiling points of
mixtures (Lab)
• Compare boiling points of a
pure substance and mixtures
• Represent these results
graphically with IV (salt
concentration) on the x-axis
and DV (boiling point temp.)
on the y-axis
Grade 8
LESSON
Familiarising students with
the laboratory (Lab)
• Review laboratory rules and
procedures
• Apply safety procedures
involving fire extinguisher
and fire blanket, chemical
shower, eye bath and
evacuation procedures
Introducing the particle
theory
• Determine prior knowledge
of states of matter
• Distinguish between the
properties of solids, liquids
and gases in terms of shape
and volume
Comparing properties of
fluids (Lab)
• Use fair testing principles to
compare properties of
various fluids
• Investigate viscosity
• Investigate diffusion rates
Elaborating on fair testing
(Lab)
• Use principles of fair testing
to design an experiment to
compare boiling points of
pure substances and mixtures
(e.g. dH2O and 5%, 10%,
15%, 20%, and 25% salt
solutions)

LESSON
LESSON
Familiarising students with
the laboratory (Lab)
• Laboratory equipment
Familiarising students with
the laboratory (Lab, Lab
Report Format)
• Identify and draw scientific
diagrams of common
laboratory equipment
Introducing the particle
theory (Lab)
• Measure experimentally the
properties of states of matter
Explaining particle theory
• Determine prior knowledge
of changes to states of
matter due to heating or
cooling and that these
changes are reversible
• Understand the five
aspects of particle theory
Exploring elements as
particles
• Understand that elements
are made up of particles
• Recognise that all the
particles in one element are
the same so it is a pure
substance
Lab Report Write Up/Control
and Variables
• Go over how to write an
effective lab report
 What are the types of
variables in a lab
(independent, dependent,
controlled variables);
sponge bob activity
Explaining particle theory
• Draw particle diagrams
using a variety of shapes to
model different types of
particles in the three states
Researching and Revision
(Computers)
• Research to apply phase
changes to everyday
situations
• Revision of the states and
properties of matter and
particle theory
Combining elements
• Use particle diagrams to
compare structures of
elements, compounds and
mixtures, as well as multiple
shapes both combined and
separate to represent
compounds and mixtures
EID BREAK
ASSESSMENT/
DUE DATES
Exploring elements as
particles
• Recall names and symbols
of some of the elements
found on the periodic table
• Relate common uses of
elements to everyday
scenarios

MEASURING PHASE
CHANGE
Sunday, Sept 20th
Elaborating on combining
elements
• Design a peer worksheet
using particle diagrams to
compare structures of
elements, compounds and
mixtures
Elaborating on combining
elements
• Identify elements and the
number of particles in
complex chemical formulas
Combining elements
• Describe uses for these
substances
• Identify elements and
number of particles in simple
chemical formulas
Elements, compounds and
mixtures in the real world
• Applications of elements,
compounds and mixtures to
the real world
Organising the periodic table
(webquest activity)
• Briefly discuss the history of
the periodic table
• Define physical properties
• Classify similar physical and
chemical properties of
elements in columns
Elements and compounds
(Lab)
• Learn the names of each
family (groups) of elements
• Relate the organisation of
rows to the increase in
number of smaller parts in
the particles until the
arrangement is stable
Remembering the first 20
elements
• Organization of the periodic
table
 Properties of metals, nonmetals, metalloids
Remembering the first 20
elements
• Design a memory tool to
remember the elements on
the periodic table
• Use techniques such as
mnemonics, songs or poems
Revision
• Revise the periodic table
• Applications to the real
world
• Periodic table Quiz
