Be able to produce word
equations to describe the
reactions of metals and acids
Be able to use symbol
equations to describe the
reactions of metals with acids
Recognise that it is dangerous
to try and react some metals
with acids
Know that a salt can be made
when a metal reacts with an
acid
Know that a salt can be made
when a relatively reactive
metal and an acid are reacted.
Know that the test for
hydrogen is that it will burn
with a squeaky pop
.
Know how to extract a sample
of salt from the reaction
between a metal and acid
Be able to know a variety of
methods of extracting a salt
from reactions of acids
Acid + metal
Acid + metal oxide
Acid + metal carbonate
Acid + alkali
Be able to produce word and
symbol equations for these
reactions and work out the
name of the salt produced from
the reactants used
Foundation
Understand that a more
reactive metal will displace a
less reactive metal from a
solution of one of its salts
Understand that some metals
are more reactive than others
and this allows us to place the
metals in order of reactivity
Understand that the reactivity
of a metal affects what it’s
uses are
Intermediate
Construct a table to show
patterns clearly
Describe displacement
reactions using word
equations
Advanced
Identify patterns in
observations and use a model
to explain these results
Describe displacement
reactions using symbol
equations
Be able to remember where
common metals are found in
the reactivity series
Use a combination of reactions
of metals to construct a
reactivity series for metals
Know that the reactivity of a
metal is linked to when it was
first used
Be able to interpret where an
unknown metal would be
placed in the reactivity series
based on its chemical reactions
Understand that 2 different
metals can be used to create an
electrochemical cell using a
type of fruit
Understand that the reactivity
of a metal is linked to the
method by which it is extracted
Understand that the value of
the voltage cell depends on the
difference in reactivity of the 2
metals used
Know that the voltage of this
cell changes when you use
different combinations of
metals
Be able to plan and carry out an
investigation to determine the
factors that can affect the
voltage of a fruit cell
Be able to recognise all the
variables that need to be
controlled in an investigation to
conduct a fair test

carbon and sulphur will react
with oxygen

with oxygen to form acidic
oxides
Use word equations to describe
these reactions

oxygen to form acidic oxides
and be able to use symbol
equations to describe these
reactions

oxides, sulphur dioxide, carbon
dioxide and nitrogen oxides are
acidic

cause a pollution problem
caused “acid rain”

warming is linked to the
amount of CO2 in the
atmosphere
Know some of the effects of
global warming on the
environment
Know that these non metal
oxides are soluble in water
Explain some of the effects of
acid rain on the environment
Know that these non metal
oxides form acid solutions
when dissolved in and these
cause acid rain
Understand how the
greenhouse effect works
Understand why the level of
CO2 in the atmosphere has
increased in recent times due
to burning of fossil fuels
Know that there are other
gases that can cause a
greenhouse effect and
contribute to global warming

using data to provide evidence
for suggesting scientific
theories

different substances contribute
to air pollution

they cause in the environment

important resource that is
needed to make a range of
fuels and chemicals
Know some uses of each
fraction
