Lady Cecily's Soundbox

A Victorian Music Hall Melodrama on Sound and Waves

The Fair Emily

“My dearest Emily’s grandmother died recently (and rather unexpectedly I’d say….) and she left to her a box of curious gadgets. I’m sure the contents would be of interest to Mr Marconi or Thomas Edison as they seem to have something to with sound and communication.

Elizabeth, Emily’s identical twin sister who, in my opinion, is perfectly ghastly, seems to be after the box too – goodness knows why. I only hope it has nothing to do with Queens Victoria’s impending visit to London or the disappearance of that gaudy but harmless flower girl Maria….”

The tale involves mistaken identities, murderous shenanigans with all the fun and gusto of the Victorian Music Hall!

“Fab – as usual! Thank you! Love the jokes that keep the staff involved too, plus the interaction between the actors, pupils and staff.”

Carly Lauder, Mayfield Middle School

Science Content Lower KS2 / KS1

Emily's twin sister, Elizabeth

Vibrations, frequency, speed of sound & light, microphones, loudspeakers

  • The children are shown that sounds are created as the result of vibrations
  • Frequency is explained as the number of vibrations each second and is related to how we hear sounds (demonstrated with the use of a signal generator)
  • How sound travels through air is illustrated and its speed compared to that of light is shown with particular reference to thunder and lightning
  • The basic functions of the microphone and loudspeaker are explained

Science Content Upper KS2

Boo hiss

Range of human hearing, amplitude, how sound travels, telephones, measuring time and distance

  • As KS1 but in greater detail…
  • Frequency is measured in Hertz and the range of human hearing
  • Amplitude is defined and its relation to the amount of energy carried by a wave is demonstrated
  • The children are shown how sound travels through air
  • The carbon microphone and its use in the telephone is explained
  • The children learn that time (or distance) can be measured using the speed of sound
