OCR GCSE Combined Science Paper 5 REVISION (Physics topics 1 - 3)

This is a fully-resourced revision lesson that could be used over a series of lessons to help students to revise and assess their knowledge of the content in topics P1 (Matter), P2 (Forces) and P3 (Electricity and magnetism) of the OCR Gateway A GCSE Combined Science specifiction which can be assessed in paper 5. This revision lesson uses a combination of exam questions, understanding checks, quick tasks and quiz competitions to cover the following sub-topics and specification points:

• Describe how and why the atomic model has changed over time
• Describe the structure of the atom and the charges of the particles
• Define the term specific latent heat
• Conversions from non S.I. units to S.I. units
• Explain the vector-scalar distinction
• Recall examples in which objects interact
• Represent forces as vectors by drawing free-body diagrams
• Know the definition of Newton’s three laws of motion
• Define momentum and describe examples of momentum in collisions
• Recall and apply Newton’s third law
• Describe the relationship between force and the extension of a spring
• Calculate the spring constant in linear cases
• Define mass and weight
• Recall that current depends upon both potential difference and resistance
• Recall and apply the relationship between I, R and V
• Show that Fleming’s left hand rule represents the relative orientations of current, magnetic field and force

This lesson contains a big emphasis on the mathematical calculations that will be involved in these exams, and as a result students are challenged to recall the equations and to apply them.

Students will be engaged through the numerous quiz rounds whilst crucially being able to recognise those areas which require their further attention during general revision or during the lead up to the actual GCSE terminal exams. A lot of the tasks have been differentiated so that students of all abilities can access the work and be challenged appropriately.
