The Technology Rocks Show
Scientific Sue received to honour of performing this show as part of Institute of Physics Tyndall Schools’ Lecture Series in 2015
Join Scientific Sue on this historical and energising scientific journey and find out about some of the really cool science and engineering behind her electric guitar.
This show is aimed at audiences of 14+ years.It covers 2600 years of scientific discoveries based on electricity, magnetism and electromagnetism which will ultimately bring some hard rock sounds to your ears! Deep Purple eat your heart out!
However before the magical world of electricity and magnetism is explored we have to investigate the science of sound. How can a straw be turned in a oboe? What happens if the length of the straw is changed or if a paper cup is added to the end?
What is a gramophone? A record player? How do they work?
We then find out how the invisible electric and magnetic forces can be used to, first of all make items levitate, then how we can visualise the effects of these magical forces and finally how they can be used to create vibrations will ultimately lead to sound.
200 years ago Scientific Geniuses such as Volta, Orsted, Ampere, Sturgeon, Ohm and Faraday brought the ideas of electric charge, electric and magnetic fields, triboelectricity, electrostatic discharge and induction to the scientific table – these forefathers of science are the ones who are responsible for what Sue considers to be ‘the’ major event of the 20th Century, the invention of the Electric Guitar!
A simple electric motor made using a key, battery, magnet and length of wire – the snail acts as a load as well as bringing a wee bit of humour to the sketch.
Static electricity demonstrations making objects fly and levitate are explored using a Van de Graaf machine, a Wandarama stick (supplied by Sue) and balloons.
Electric guitars revolutionised the sound of music and they are the very definition of rock music.
Although the science extends into areas beyond KS4, this show can be adapted to suit all audiences.
Technology Rocks Tyndall 1
Apologies are made now for her musical abilities however don’t worry… volunteers will be invited on to the stage to strum out their favourite tunes and even if their playing isn’t so hot we are then shown how technology can come to the rescue.
The science and engineering used in this show can be used to make amazing Jitter bugs, robots and other critters.
This show covers the following themes and topics:
- Science behind an electric guitar
- Energy and energy changes
- Static, DC and AC electricity
- Force fields: gravitational, electric and magnetic
- Sound: pitch and loudness
- How loud speakers work
- How motors work
- How electricity is generated
- The impact on engineering and technology on our lives today
