Run For Your Light

Whilst we usually think of light as a wave, it's actually made up of billions of tiny particles called photons - researchers are looking for ways to harness photons to develop a multitude of exciting technologies. In these teaching resources, students look at the use of encryption in computer science (KS3); carry out Young's double-slit experiment (KS4) and explore what this means for quantum theory (KS5); and looks at the energy levels of atoms to explain how photon emission can be harnessed for technology (KS5).

KS3 - Encryption
KS4 - Wave or Particle?
KS5 - Artificial Atoms
KS5 - Quantum Quirks
In this computer science lesson students are introduced to encryption. They model the way that information is transmitted by the internet and try and protect their messages using different keys.
Students will apply their knowledge about wave behaviour to explain the results from Young's double slit experiment and get first-hand experience of how scientists use experiments to test hypotheses.
This activity is suitable as a follow-on lesson after students have studied energy levels and photon emission and asks them to explain what quantum dots are and how they can be used.
This activity is suitable as a follow-on lesson after students have studied Young's double slit experiment. It asks them to interpret data from a single photon double slit experiment as an introduction to quantum theory.
