AQA GCSE Physics – P1 Revision Presentation
One of the most effective ways to learn a subject thoroughly is to teach it to
others – this is why your teachers have so much knowledge about their
subject – so in order to revise for the Y10 examination we are going to create
a revision presentation for the rest of the class on a particular topic from P1.
Remember the stuff about forces and motion that we are doing at the
moment is P2
Each small group will be allocated a section of the syllabus. The table below details the different sections together
with what you need to include in your presentation.
In addition to the presentation, I also want each group to produce a crib sheet with all the essential facts, formulae
and definitions. On this sheet (or sheets) you should try to generate a couple of exam style-questions for the rest of
the class to answer, to test their knowledge.
The section of the syllabus together with things you need to include in your presentation/crib sheet, are below:
