Demonstrating Physics: Radioactivity

Produced by Teachers TV, this video illustrates demonstrations of radioactivity suitable for Key Stages Three and Key Stage Four students. The techniques shown could be adapted by teachers working with post-16 students.

David Richardson from the Institute of Physics shows three teachers from different backgrounds how they can handle radioactive resources safely, and carry out effective experiments in the classroom.

David shows a range of experiments using alpha, beta and gamma ionising radiation. Supporting animations help explain what is happening on an atomic level. David also gives the teachers some suggestions for starter activities to help their students engage with the lesson.

Additional safety points are covered by John Ellis from CLEAPSS, the school science support service.
