Light

Science Year 5/6 Theatre Lighting Technicians

A job opportunity has arisen at the National Theatre for a lighting technician and you have been asked to apply! You will need to put together a portfolio for the interview demonstrating that you have the skills and knowledge to put on a colourful and effects-driven show. You will need to make sure you have the technical know-how as well as a sound understanding of the science behind the behaviour of light.

Session 1 Shadow puppets: angles, shape, definition

  2. Taking measurements, using a range of scientific equipment, with increasing accuracy and precision, taking repeat readings when appropriate
  3. Recording results using scientific diagrams and labels and tables
  4. Using test results to make predictions to set up further comparative and fair tests
