Waves CPD videos

CPD for 11-14 14-16 16-19 IOP RESOURCES

Essential in our everyday life, waves are used in many forms of communication. Wave phenomena such as rainbows and interference patterns inspire awe and wonder. This series of videos provides useful ideas and practical tips for teachers. We also address some common misconceptions that often surface and how best to deal with them.

The short CPD videos below can be used alone or as preparation for a session in our online  IOP DOMAINS CPD Programme.
