emphasis
 understand that metals
can be arranged in a
reactivity series based on
the reactions of the
metals and their
compounds: potassium,
sodium, lithium, calcium,
magnesium, aluminium,
zinc, iron, copper, silver
and gold
Starter - ask pupils to work in
pairs and put a set of given
metals into a reactivity series.



Review – use Reactivity Series
in e science. How has this
order been worked out?
Which reactions can we use to
test it?
Focus on Metal + Water
Metal + Acid
Displacement
reactions in solution and with
metal oxides.
Write general equations for
these reactions.
Activity – consider which
reactions could be used to test
which parts of the Reactivity
Series. Use their prior
knowledge for this. Consider
things such as copper water
pipes, Thermit reaction etc.
Plan a series of reactions
suitable to test the series. Try
to let students have as much
ownership as possible but also
advise them which reactions
will need to be demonstrated
by a teacher.
Students complete
their plan for
homework.

lesson.
Students carry out Ca in water
and test for hydrogen.
Demo Mg with steam, consider
the reactivity of zinc in the light of
this – very slow in cold water but
will react with steam to produce
ZnO and H2
Plenary – place these metals in a
reactivity Series based on these
reactions. Predict the reactivity of
Fe and Cu from their prior
knowledge ( common sense!)

Metals with Acid
Student react Ca, Mg, Zn and
Cu in 1.0 moldm-3 HCl.
Test for hydrogen
NB Zn must be started as
early as possible in the
lesson and left with a bung
in to stand any chance of
producing H2. It may be
prudent to have one set up
earlier to demo if students
have no reaction.
Write word equations for the

Properties
of iron and
steels
Learning Objectives

The properties of pig iron
and how this limits its
usefulness.

That iron can be alloyed to
make it more useful.

understand that a metal
can be described as a
giant structure of positive
ions surrounded by a sea
of delocalised electrons
Most students should be able to:
• List the properties of iron produced
from the blast furnace.
• Explain why steels are produced.
Some students should also be
able to:
• Explain why alloying changes the
properties of a pure metal in terms
of its structure.
• Give examples of different types of
steels, their chemical content and
how their differ.properties
Activities

Starter - get pupils to list
as many properties of iron
as they can and link them
to uses.
