Activities
Explain the organisation of the periodic table.
Explain the arrangement of an atom.
Review the organisation of the periodic table.
Highlight the periods. Explain the chemical and
physical properties and trends of the alkali
metals, the alkali earth metals, the transition
metals, the halogens and the noble gases.
Review the structure of the atoms, the charges
and masses of all subatomic particles and electron
structure.

Complete assessment task 1a.
Students to produce a poster on the organisation of the periodic table.
Students to show the electron arrangement of the first 20 elements – Use A3 sheet resource sheet
on electron structure
Explain the bonding present in ionic compounds.
Review ionic and covalent bonding. Students to

example sodium chloride, an organic acid such as
lactic or acetic acid, an inorganic acid such as
hydrochloric acid or nitric acid.
Complete assessment task 1b.
Students to produce a leaflet explaining the bonding present in ionic and covalent compounds. They
must explain the movement or sharing of the electrons, the interactions present and give examples of
a salt, an inorganic acid and an organic acid.

Explain to students how titrations can be used to
assess the accuracy of a standard solution. Work
through some examples with the students.
Complete assessment activities 2a and 2b
Students are to prepare a 100ml 1Mol sodium hydroxide solution and a 100ml 2Mol sodium hydrogen
sulphate solution. Complete the observation sheet on standard solution
Students to titrate 25ml of their sodium hydroxide against a known concentration of hydrochloric acid
using phenolphalein as an indicator. Students to repeat the investigation 3 times to calculate the
mean.
Students to titrate their sodium hydrogen sulphate solution against a known concentration of sodium
hydroxide using phenolphalein as an indicator. They are to repeat 3 times to calculate a mean.
Complete the observation sheet on performing a titration.
Complete assessment activities 2a and 2b
Students to write a report on how they made their standard solutions, highlighting the importance of
using the periodic table in the calculations. They are then to explain how they assessed the accuracy
of their prepared solutions.
Explain how they produce standard solutions and Allow students to carry out research as to how
assess their accuracy in industry
standard solutions are carried out in industry and
how they are different to the procedures that they
have carried out. Explain how standard solutions
are assessed for their accuracy in industry.
Students to complete assessment activity 3.
Write a report on how standard solutions are prepared and tested for their accuracy in industry and
how these procedures differ from that done in the school laboratory.
