PAPER 3 FT REVISION (Edexcel Combined Science FOUNDATION TIER)

This is a fully-resourced lesson which uses exam-style questions, quiz competitions, quick tasks and discussion points to challenge students on their understanding of the content in topics C1 - C4, that will assessed on PAPER 3. It has been specifically designed for students on the Edexcel GCSE Combined Science course who will be taking the FOUNDATION TIER examinations but is also suitable for students taking the higher tier who need to ensure that the fundamentals are known and understood.

The lesson has been written to cover as many sub-topics as possible, but the following have been given particular attention:

• The relative mass and charge of protons, electrons and neutrons
• Using the Periodic table to calculate numbers of the sub-atomic particles
• Writing elements and compounds in chemical symbol equations
• Simple and giant covalent structures
• Explaining the difference in conductivity of graphite and diamond
• Drawing dot and cross diagrams for ionic compounds
• The transfer of electrons during the formation of an ionic bond
• Writing chemical formulae for ionic compounds
• Conservation of mass and balancing symbol equations
• Calculating the relative formula mass
• Electrolysis of molten salts and aqueous solutions
• Extraction of metals

In order to maintain challenge whilst ensuring that all abilities can access the questions, the majority of the tasks have been differentiated and students can ask for extra support when they are unable to begin a question. Step-by-step guides have also been written into the lesson to walk students through some of the more difficult concepts such as drawing dot and cross diagrams, diamond and graphite and writing chemical formulae.

Due to the extensiveness of this revision lesson, it is estimated that it will take in excess of 3/4 teaching hours to complete the tasks and therefore this can be used at different points throughout the duration of the course as well as acting as a final revision before the PAPER 3 exam.
