Check
Date
Revise assumed knowledge:
SC4-16CW
describes the observed properties and behaviour of matter, using scientific
models and theories about the motion and arrangement of particles
□
SC4-17CW
explains how scientific understanding of, and discoveries about the properties
of elements, compounds and mixtures relate to
their uses in everyday life
CW2 The atomic structure and properties of elements are used to organise
them in the Periodic Table. (ACSSU186)
5CW2a. identify the atom as the smallest unit of an element and that it can be
represented by a symbol
5CW2f. outline some examples to show how creativity, logical reasoning and
the scientific evidence available at the time, contributed to the development of
the modern Periodic Table
Recall that the periodic table is organised by atomic number
Introduce the format of the current periodic table and compare it to previous
versions developed throughout history
Recall that each element has a particular location i.e. group and period
and what that location signifies for each element
Explain that the current periodic table is the product of developments
over time through history with many changes and modifications having
been made in that time
Activity 2.1.1 Discovery of the elements Oxford pg 51
Checkpoint 2.1
Complete questions as homework, a mid-topic test or as a class activity.
Use individual student scores to assign support, consolidate or extend
checkpoint worksheets from the Teacher obook as required
5CW2b. distinguish between the atoms of some common elements by
comparing information about the numbers of protons, neutrons and electrons
5CW2c. describe the organisation of elements in the Periodic Table using their
atomic number
Distinguish between metals and non-metals according to their properties
First hand investigation 2.2.1 Reactivity of metals Oxford pg 56
Distinguish where on the periodic table the alkali metals, alkali earth
metals, transition metals, metalloids, halogens and noble gases are located.
Recall the name, symbol, colour, features and uses of at least three
common metals
Recall the name, symbol and special properties of at least two metalloids
and their location on the periodic table.
Recall the name, symbol and characteristics of at least two non-metals

Checkpoint 2.2
Complete questions as homework, a mid-topic test or as a class activity.
Use individual student scores to assign support, consolidate or extend
checkpoint worksheets from the Teacher obook as required
5CW2d. relate the properties of some common elements to their position in the
Periodic Table
5CW2e. predict, using the Periodic Table, the properties of some common
elements
Explain the link between periodic table groups and the number of
electrons in valence shells
Explain why ions form.
Write formulas of ionic compounds given the starting ions, e.g. Mg+2 and
Cl- and recall three properties of ionic compounds
Explain why metals are good conductors
Recall three properties of covalent compounds
COSMOS. Students to research and locate an article in COSMOS. Read,
review article and write questions for peers.
Checkpoint 2.3
Complete questions as homework, a mid-topic test or as a class activity.
Use individual student scores to assign support, consolidate or extend
checkpoint worksheets from the Teacher obook as required
