KS3 CHEMISTRY:
Periodic Table
This is one of a series of documents designed to support science departments to integrate engaging and purposeful practical and investigative science activities within their current schemes of learning.
They highlight opportunities throughout the KS3 National Curriculum and identify possible purposes for each activity relating to the ‘Getting Practical’ project.
About this section of the curriculum
Pupils should be taught about:
• the varying physical and chemical properties of different elements
• the principles underpinning the Mendeleev Periodic Table
• the Periodic Table: periods and groups; metals and non-metals
• how patterns in reactions can be predicted with reference to the Periodic Table
• the properties of metals and non-metals
• the chemical properties of metal and non-metal oxides with respect to acidity.

Learning demand
The key concepts in this section of the curriculum are the development of the periodic table, elements, families of elements,
periodicity and the properties of matter: physical and chemical.
The structure of the Periodic Table appears very complex to young scientists. The more opportunities that pupils have to
undertake practical activities and identify patterns and trends in the groups and periods, the quicker their understanding will
develop. For further information and support, see the Secondary National Strategy materials: ‘Strengthening teaching and
learning of particles’.

Where this section of the curriculum fits in
This section of work covers some aspects of several QCA topics. The most significant links are:
8E Atoms and elements
This section of work follows on from the KS2 curriculum where pupils are taught to:
•e
xplain that some changes result in the formation of new materials, and that this kind of change is not usually reversible,
including changes associated with burning and the action of acid on bicarbonate of soda (Y6)

Expectations
Within this section of the curriculum in terms of working scientifically
all pupils will: find information from selected secondary sources about elements and their properties
most pupils will: select information about elements and their properties from a range of secondary sources; identify an
approach to finding out whether a material is an element or not and explain how their results provide appropriate evidence
some pupils will have progressed further and will: select secondary sources to provide the information needed
about elements and their properties; identify limitations of evidence obtained about whether a substance is an element or
not, where appropriate, suggesting alternative explanations
in terms of Chemistry: Periodic Table
all pupils will: name some elements and represent these by symbols; distinguish between symbols for elements and
formulae for compounds; name a wide variety of materials
most pupils will: recognise that there is a small number of elements and name some of these; explain that compounds
are made when atoms of different elements join together; begin to use symbols for elements and to represent reactions in
word equations
some pupils will have progressed further and will: identify elements whose properties do not fit the general
pattern of metals and non-metals; begin to represent compounds by formulae; make links between this section of the
curriculum and others

• discuss and question what they are learning
•u
ndertake independent research using knowledge of how texts and databases are organised and using appropriate
reading strategies

• use the internet to research the ideas of elements by Döbereiner, Newlands and Mendeleev.
• research the history of how scientific ideas have changed over time with regard to the similarities and differences between
Mendeleev’s Periodic Table and the modern Periodic Table

each element:
- its symbol
- its state at 20°C
- density
- whether it is described as a metal or a non-metal
- whether it is described as magnetic or not
- hardness
C1
- conductivity
- melting point
Element cards

- solubility in water
- its appearance (including colour)
- any other information they might think important
This activity involves pupils in researching and recording the required information, describe
some differences between elements and make some generalisations about elements
http://www.rsc.org/periodic-table
http://www.chemsoc.org/viselements /pages/data
Using fact cards to identify similarities and trends between elements in the same group
of the periodic table
This activity allows pupils to build upon each other’s ideas and hence develop their
own understanding further, and to identify trends and patterns
Possible misconceptions:
-
the Periodic Table has always been the same as it is now
it was agreed that there was only one way to categorise the elements
science provides absolute truth rather than being evolving
we know all there is to know about atoms and elements

Researching the Mendeleev Periodic Table to identify:
- patterns
- periodicity
- how it was underpinned by ideas and evidence

Classifying elements by physical properties
This activity involves pupils in researching and making first hand observations
through investigations of physical properties to identify trends and patterns.
