The following document gives a possible method of planning a module for Module 1: People Moving, Moving People. It gives a breakdown of how the content for this unit could be taught, it indicates how topics can be clustered together with an approximate teaching duration and resources required. Details of some possible actives to support teaching are provided in the right hand column. If you have additional activities that you would like to share with teaching colleagues please contact the subject team who will update this document periodically.

Activities Description Identify quantities from present knowledge Review GCSE knowledge Train journey times from national rail timetable Determine speed using light gates or web cam Acceleration using 2 gates + slope Test v2 = u2+2as with one gate + dl; measure known distance Measure g demo(not in exam as required practical) Modellus modelling (free software) Measurements of acceleration from falling chimney video (You Tube) or Cambridge multimedia Motion Non-uniform acceleration examples from video / You tube.

Now decide on a teaching order and identify possible resources / experiments / activities available.
